Ida Rolf on The plumb line

The plumb line is the measuring stick every school of body mechanics uses, but Ida claimed her practice was the only one that taught how to actually build a body around it. In her 1974 Healing Arts lecture, in the 1975 Boulder advanced class, in the 1976 advanced class in New Jersey, and across the public tapes, she returns to the same image again and again: a vertical line registering the alignment of ankles, knees, hip joints, lumbar bodies, shoulders, and ears — and parallel to that, a second line, the gravitational vertical of the earth itself. When the two coincide, the body is no longer fighting its environment; gravity becomes nourishment rather than wear. This article gathers her statements on what the vertical line is, how the body's horizontals serve it, and why she insisted the line is an index of relationships rather than a posture to be held. It draws on her own voice and on the colleagues — Valerie Hunt, Bob, Steve Weatherwax, Chuck — who tested the doctrine in dialogue with her.

The line as the measuring stick of every school

In her 1974 lecture for the Healing Arts conference, with Valerie Hunt and Julian Silverman in the room, Ida laid out the doctrine that would anchor every later statement about the vertical. The line itself is not her invention — every twentieth-century school of body mechanics uses some version of it as a measuring stick, and she names the Harvard group as exemplary. What she claimed was different: every other school could measure the line but none could teach the body how to occupy it. The line registers a set of alignments — ankles, knees, hip joints, the bodies of the lumbar vertebrae, shoulders, ears — and the question is whether these alignments are present or absent in a given body. The measuring stick is shared property. The means of producing it is what she said her work uniquely offered.

"This vertical line registers the alignment of the ankles, with the knees, with the hip joints, with the bodies of the lumbar vertebrae, with the shoulders, with the ears."

In her 1974 Healing Arts lecture, Ida names the line by its anatomical registrations:

This is the canonical enumeration of the alignments the line is supposed to register, and it appears in nearly identical form across her teaching.1

She immediately distinguished her position from that of the schools who use the same yardstick. The Harvard group and the various physical-education programs of the early twentieth century — Mensendieck, the Swedish gymnastics imported into Frederick the Great's army, the postural instruction given to American schoolboys and soldiers — all could name the vertical but could only ask the student to maintain it through effort. In Ida's reading, effort itself is the sign of failure. A body that has to strain to occupy the line is a body whose structure does not support the line; what is being held in place is a posture, not a structure.

"This vertical line is reminiscent of the prickles on the chestnut burrow. All those prickles pointing straight toward the center of the earth. If the lines are substantially vertical. This is a static verticality, however. This is the verticality taught by every accepted school of body mechanics operating in this century, and the Harvard group heads the list. All schools of body mechanics teach this measuring stick and verticality, but no other school of body mechanics teaches how to achieve it. But because the body has an unforeseen, unexpected quality, it can be done. The body is a plastic medium."

She continues in the same lecture, drawing the contrast with the schools that share her yardstick:

Here she names her own claim — that the body is plastic, that the line can be built, not just measured — as the doctrinal break with twentieth-century body mechanics.2

Structure is relationship; posture is what you do with it

The semantic distinction between structure and posture sits at the heart of how Ida wanted students to think about the line. In a Topanga lecture preserved among the short clips, she walked the audience through the etymology — posture from the Latin to place, meaning something has been placed, that someone is maintaining a placement — and contrasted it with structure, which she insisted always names a relationship between parts. The line is not something a body is placed into; it is the geometric register of a particular set of relationships. If those relationships are right, the line appears; if they are wrong, no amount of effort to assume the line will produce structural alignment.

"Posture is what you do with structure. Structure is the way you relate parts of the body to each other. And if you are really going to understand what I'm talking about tonight, a little meditation on those two words wouldn't do any harm."

In a Topanga lecture, she gives the operational definition she wanted students to meditate on:

This is the doctrinal one-liner that underlies every later teaching about the line — posture is the consequence of structure, never the means of producing it.3

The distinction has a practical consequence she returned to constantly. When she watched a man struggle to maintain posture — shoulders held back, gut held in, chest forward in the manner the U.S. Army drilled into its recruits — she read that struggle as the body losing its fight with gravity. The line in that body is being chased, not occupied. Effort is the diagnostic sign. In the same passage she names the alternative: when structure is in balance, posture is automatic, and the line is simply where the body lives without instruction.

"Nineteen twentieth century, last part of it, last quarter of it, that to keep any of these bodies in posture takes effort, constant continuous effort. And when you have to make effort concerning anything in your body, it's a very bad sign. You don't usually interpret it in view of the next words. But as I see a man struggling to maintain posture, I know that he is losing his fight with gravity. That's one item. And I know that his structure is not in balance. Because if his structure is in balance, his posture automatically is good. Posture is what you do with structure."

She presses the diagnostic point — effort is the symptom, not the cure:

She converts the structure/posture distinction into a clinical reading: a man working to hold his line is a man whose structure has already failed.4

Why vertical — gravity as the nourishing field

Ida's reason for insisting on verticality was not aesthetic. It was a claim about energy. The earth's gravitational field is a vertical force, and a body whose own vertical coincides with that field, she taught, receives the field as support; a body whose vertical is at odds with the field is broken down by it. This is the move that takes the line out of the postural-correction tradition and into what she called the physics of the body. The line is the place where the two verticals — the body's and the earth's — meet, and the meeting is what makes gravity into a nourishing rather than a destructive force.

"And the answer is simple and really expected. Back to shape in this context means vertical. Vertical to the surface of the earth, vertical like the burrows of the chestnut, vertical like the force of gravity. Because only when the gravity vertical of the body substantially coincides with the gravity line of the earth can that energy field of the earth reinforce and augment the field of the human body. Then the energy of the earth contributes to the energy of the body. The body becomes vitalized. The flesh becomes resilient. Body functions of all sorts improve, for gravity at this point is the nourishing factor. Gravity is the nourishing medium giving to the energy quotient man gravity a higher value, because the man is more energized. This expresses itself in many changes in behavior patterns. Among them, among them is a different state of consciousness. We usually refer to it as a higher state. We have described the body as a plastic medium."

In the same 1974 Healing Arts lecture, she draws out the physics:

She names gravity as a nourishing factor rather than a wearing one, contingent on the coincidence of the body's vertical with the earth's. This is the energetic argument for why the line matters.5

Valerie Hunt, who became Ida's principal scientific collaborator, attempted to give this energetic claim a measurable form. In her own contribution to the Healing Arts conference she described the studies she was running at UCLA — the changes she could record in baseline bioelectric activity after the work, the smoother sequencing of muscular contraction, the broader and more dynamic movement patterns. Hunt's framing makes clear what Ida meant by gravity as a therapist: as the body's segments align with the field, the field can flow through them, and the effects can be registered downstream in measurable physiological terms.

"We have every reason to believe that this project will lend itself to measurement. Her findings seem to be saying loud and clear that as a man approximates the vertical, that is ears over shoulders, shoulders over hips, hips over knees, knees over ankles, certain very significant changes occur in the kind of neuromuscular behavior, can and these changes can be registered and they can be recorded by electromyographic and electroencephalographic measurements. Ralfas in general are not sufficiently scientifically sophisticated to demand measurements. They're willing to settle with contour, with form, without with recognizing the outward form of contour."

Hunt, presenting at the same 1974 conference, makes the same claim in the language of measurement:

Hunt's verticality is Ida's, but converted into a research hypothesis — that the approximation of vertical alignment produces registrable neuromuscular changes.6

The horizontals as the index of the vertical

If the vertical is the line a body lives around, the horizontals are how a practitioner reads whether the body is succeeding at it. In a 1971-72 Mystery Tape exchange, Ida pressed her students to articulate the relationship. The body's hinges — the ankle, the knee, the pelvis — function optimally when their axes are horizontal. If the body is balanced around the vertical, those hinges will be horizontal; if the hinges are tilted, the vertical has failed. The horizontals do not produce the vertical; they register it. This is the move that gives a practitioner something to look at, since the vertical itself is invisible but a tilted shoulder girdle or a spilling pelvic bowl is not.

"The horizontal line is the index. It's the outward and visible sign in the words of the good old catechism of the inward and spiritual grace."

In a 1971-72 exchange preserved on the Mystery Tapes, she names the relationship between horizontal and vertical with characteristic theological wit:

She borrows the Anglican catechism's phrase to claim that the horizontal line is the visible sign of the invisible vertical relationship — the practitioner's eye reads the horizontals to know whether the vertical is present.7

She extended the point by naming what produces the horizontals. They are not held in place by muscular effort; they are the consequence of weight distribution and fascial tension being in the right relationship. When the structures are placed correctly and the weight is distributed correctly, the hinges become horizontal of themselves. The horizontal is therefore a passive index — it appears when the underlying conditions are present. Peter, one of the students in the same Mystery Tape session, attempted his own formulation in terms of the head of the femur floating in the cradle of the acetabulum without muscular effort. Ida accepted the description as one definition of balance but cautioned that the field was full of osteopaths who would claim the same thing for very different reasons.

"And this is where we get into trouble because there are several ideas of balance around the world and we're defining one and it has not been one that has been brought forth over several centuries now. I think it was known in the days of the Egyptians. I think that's what the factions say. Now, our balance, our horizontal horizontal comes comes out out of of the interaction of preplane. Knees moving forward, the elbows moving outward and the hips moving upward. Now those three claims have to be related before I accept it as balance. And those three claims, me being people are not theoretical claims that practical claims are the practical movement in the body of certain significant specific forms. And this puts it in to a three-dimensional material world. And all the rest of this stuff that you've been talking about has been in the realm of the anatomy books and not of the physiology physiology books. Yesterday when I was feeling the horizontal and I could feel them in one dimension. You can feel them right."

Pressed on what distinguishes her balance from the chiropractor's or the osteopath's, she gives the practical answer:

She names the three specific movement-claims — knees forward, elbows outward, hips upward — that have to be true before she will accept a body as balanced. The horizontals have to be the consequence of actual joint movements, not theoretical positions.8

The center line and the inside of the leg

In the 1976 advanced class, Ida ran an experiential demonstration of where the center line actually goes. She asked the students to stand and find the line within themselves, then to shift weight to the outer arch of the foot and notice what happened to their sense of unity. The exercise served as a corrective against a piece of received doctrine she heard everywhere — that weight should pass through the three center toes. The chunks preserve her irritation with the formulation. The center line, she insisted, runs down the inside of the leg, and weight that falls onto the outer arch destroys it. The doctrine of the three center toes confuses an abstraction with a felt experience, and the felt experience is what teaches the practitioner where the line actually lives in a body.

"What happens? You lose your line. Yeah. It's called you're no longer a unit."

Demonstrating in the 1976 class, she asks the students to feel what happens when the line goes:

The single-line aphorism — losing the line means you are no longer a unit — is one of her most compressed statements of what the line is for.9

She extended the demonstration into a positive instruction. Turning the toes up, she said, redistributes the weight back onto the inside of the foot and begins to re-establish the line up the inside of the leg into the body. The instruction is not aesthetic; it is a way of asking the body to feel where its line actually lives. She repeatedly framed this as the silent level of the work — the level at which the body itself tells the practitioner what unifies it — as opposed to the verbal level of received postural doctrine. The line is a felt reality before it is an idea about a body.

"Your center line connects down the inside of the leg. Your center line is destroyed as weight goes on to the outer arch. Now just turn your toes up and see how that begins to put the weight back again into the center line."

She names where the line runs in the leg and what destroys it:

She corrects the popular three-center-toes doctrine with her own anatomical claim: the line runs down the inside of the leg, and the outer arch is where it gets lost.10

The same demonstration sat against a story she told about the dancer Ruth St. Denis, whom she had known and admired. St. Denis had written in her diary that on certain nights she could not dance well because she could not find her line. Ida used the anecdote to make a broader point about how knowledge about structure gets into the culture — sometimes through someone like her, putting a nickel in the slot and watching the answer come out, and sometimes through dancers who articulate from their own bodies what physics laboratories are slower to discover. The center line, by this reading, is an old piece of human knowledge that the work merely formalizes and teaches a practitioner to evoke.

The blocks and the stacking

Wherever Ida had to explain the line to people who had never received the work, she resorted to the same image: the body as a stack of blocks. The head, the thorax, the pelvis, the legs — four major segments that can be stacked well or stacked badly. When they are stacked well, the line passes through them; when they are stacked badly, the line is broken at one or more junctions, and the body's energy budget is consumed in compensating for the misalignment. The image was her staple at every public lecture, and she taught her practitioners to use it when introducing the work to lay audiences.

"front of you and visualizing him as a set of blocks. And how do those blocks go? And how would you wish to see those blocks? And how do you see those blocks? And what must be changed to get those blocks stacked vertically one on the other? And this is the story of what we do. It is not the story of how we do it. It is the story of what we do, and you will see a certain amount of how we do it. But one of the booby traps in this system is that it looks so simple that you go home and you try it on your mother-in-law. Now you may think I'm joking, but this has happened to me. I one time spoke to, I don't know, at least three or 400 people in the chiropractic college in Canada. And this introductory talk was an introduction to a course I was going to give six weeks later, something of that sort."

In the Topanga lecture she walks her audience through the blocks:

The image of standing in front of someone and seeing them as a stack of blocks is her standard introduction to what the line is for and how the practitioner sees a body.11

The stacking image carries a hidden teaching about energy. Ida treated the body as an algebraic sum of energy contributions — some organs adding, some subtracting — and the stacking determines whether those contributions reinforce or cancel. In the 1973 Big Sur class she walked the students through the same image with the energetic gloss in front. A liver functioning badly is subtracting from the total; a body badly stacked is subtracting from the gravitational input. Both can be improved, but the stacking is the one the practitioner has direct access to.

"Some of those systems are going to be pluses and some of them are going to be minuses unless you are very well stacked. Now you can add to that energy by the stopping. If you set those blocks properly, you can get maximum efficiency in the way that the body works. But you have to stack your blocks properly. As soon as your blocks get unstacked, then you begin to lessen the efficiency. Now, as I told you before, in structural integration, we think in terms of we work in terms of the stacking of the blocks which are part of the myofascial system, the connective tissue system, the collagen system."

In the 1973 Big Sur advanced class she names the energetic stakes of the stacking:

She converts the blocks image into an energy-budget argument: well-stacked blocks produce maximum efficiency; unstacked blocks dissipate the body's energy into structural compensation.12

Pelvis as the hinge — horizontalizing the bowl

Of all the horizontals, the one Ida named most often was the pelvis. Across many classes she described the pelvic bowl in most random bodies as spilling forward, its rim tilted out of horizontal, the contents of the torso unable to sit in it properly. The whole arc of the ten-hour series, she said, was about horizontalizing that bowl — bringing it back into the plane that lets the spine come up out of it cleanly. Other practitioners working with the recipe in 1974 described the same thing to lay audiences in nearly identical terms. The pelvis is the structural hinge between the legs that bring the gravitational support upward and the torso that has to balance on top of it.

"You see in the first hour, we're not trying to get everything. The goal, of course, in all the hours is to horizontalize the pelvis. Pelvis is like a bowl. And in most people, the bowl is spilling over forward. And our goal is to bring that bowl horizontal so that the contents of the torso sit in the bowl properly. So part of the training is to see the result of process. As well as to see what you do next in the process."

In a 1974 Open Universe class, one of Ida's practitioners explained the pelvic goal to a visiting audience:

The image of the pelvis as a bowl whose rim must be brought to horizontal is the standard public-facing version of the line's pelvic claim, and it shows how the doctrine traveled into the wider practitioner community.13

Ida's own version was sharper. In the 1975 Boulder class she pressed the students to recognize that what they were really working on was not the bony pelvis at all but the floor of the pelvis. When they said pelvis, she insisted, they were talking about the floor. The horizontal of the bowl is determined by the horizontal of its floor, and the work of bringing the bowl level is the work of bringing that floor level. This refinement — pelvis read as floor of the pelvis — was one of the doctrinal corrections she pushed in the later advanced classes, and she expected her senior practitioners to make the shift.

"And you were talking as though you were dealing with the bony. One is equivalent to the other practically, but nevertheless, I'd like to get this into your imagination. That this fifth hour has to do with the horizontalizing of the floor of the pelvis. Now I haven't heard anything in this class nor do I hear much in any classes come to think of it. To indicate that you people recognize the fact that it is the floor of the pelvis, that is the vital structure in this trip. We talk about pelvis. We are really talking about the floor of the pelvis."

In the 1975 Boulder fifth-hour class she corrects the students' framing:

She converts the pelvis-as-bowl image into a more precise claim about the floor of the pelvis as the operative horizontal — a doctrinal sharpening she made in her late teaching.14

The line as cumulative — each hour builds it

The line is not produced in any single hour. Across her teaching Ida insisted that the ten-hour series is a single integrative process, with each hour extending the line a little further into the body's depths. In the 1975 Boulder class one of her senior practitioners articulated the principle that the first hour is the beginning of the tenth — that every later hour continues what the first opens. The breakdown into ten sessions, Ida had told them, was a matter of practical limit; the body could not absorb the whole work at once. Conceptually, the series is one continuous act of bringing the body around the line.

"The first hour is the beginning of the tenth hour. Okay? Uh-huh. The second hour is a follow-up of the first hour. Uh-huh. It's just the second half of the first hour. Okay? And the third hour is the second half of the second and first hour. It's literally a continuation. I clearly I clearly saw, you know, last summer that continuation process and how and, you know, Dick talked about how, you know, the only reason it was broken into 10, you know, sessions like that was it because the body just couldn't take all that work. Couldn't take it right. But I just sitting on just trying to figure out how the hell she ever figured out that process, and then began to see it."

In the 1975 Boulder class a senior practitioner reports the principle Ida had been pressing in that summer's teaching:

The doctrine that each hour is a continuation of the previous makes clear that the line is built cumulatively, not produced in any single session.15

On a public tape Ida walked the same logic through the second hour explicitly. The first hour opens the trunk to the pelvis from above and the legs to the pelvis from below; the second hour returns to both ends to set them up to balance over a horizontalized pelvis. The body is still on the same trail — the trail of getting the segments to stack vertically over each other so that gravity has no moment of rotation by which to break the body down. The line is the abstract description of what zero moment of rotation looks like. Every hour is a step toward that condition.

"So the second hour becomes a putting of a support on the the pelvis. And it consists also of a lengthening the back in order that that you can balance the trunk up over the pelvis. You see, you're still on the same trail that you were on that first hour. That first hour, you started up on the trunk to get it free to the pelvis. You went down to the legs to get it free to the pelvis. Now you go down to the legs to give it formation. You come up to the pelvis again. You go up to the trunk again. And you go up to the trunk in order to get it out of this posture and into this posture. Because when the one is sitting on top of the other, there is no moment of rotation on the part of gravity to break it down. And all the rest of it are little tricks within it, you see, to make it possible to do that. The trick trick was how do you how do you get that back lengthened. I remember what a time I had with Bill Schutz who insisted on believing that you lengthen a muscle by going along it and lengthen it, but you don't. You must when you lengthen a muscle by going across it, etcetera, etcetera. But those are tricks within this single simple minded notion of what you wanna do with that body in order to get it balanced within the gravitational field. And those of you that remember your physics, remember that it is a question of getting the moment of rotation retired zero or as near zero as you can make it. And you can only do that by getting this ready for alignment. So now we have been talking about another trick. And the third trick is that when we work, we work from the periphery toward the center. Now when you come right down to it, we've been doing that in the second hour."

On a public tape she lays out the through-line of the early hours:

She names the structural goal — zero moment of rotation, segments stacked over each other — as the physical condition the line describes, and the early hours as iterative passes toward it.16

In the 1975 Boulder class Ida pressed Steve Weatherwax to articulate the fifth hour's place in the same cumulative arc. Steve's answer — that since the first hour the work has been horizontalizing the pelvis, that the chest has been lifted and the back lengthened and a midline begun, and that the front now needs to be lengthened to bring the pelvis up anteriorly — gave Ida what she wanted as the structural through-line. The fifth hour is the continuation of the fourth, which was the continuation of the second, which began what the first opened. Each hour is a further refinement of the same single act.

"And we've gotten to the place now, we've uplifted the chest, lengthened the back sides, opened up the sides, and we started to establish a midline. And now we see that the front is beginning to need to be lengthened also. How come? From the pull of the thorax and the position of the pelvis. And the pelvis has to come up more anteriorly And by lengthening the rectus, we begin to get that and we begin to get a more total integration between the upper half and lower half. It's a very good job. A very good job. Compliment to you. And this is the answer, only Steve didn't give you quite the full key. The full key is that this has to do with the floor of the pelvis. And you were talking as though you were dealing with the bony."

Steve Weatherwax, pressed by Ida to name the fifth hour, articulates the cumulative logic she had been teaching:

Steve's answer demonstrates how Ida's senior practitioners had absorbed the doctrine that each hour is a further refinement of the same single act of bringing the body around the line.17

Building toward the line, not toward an aesthetic

Visitors to the work often asked Ida whether the line was an aesthetic preference. The 1974 Open Universe transcripts preserve one such exchange, in which a visitor pressed a practitioner on whether the criterion of balance was anything more than a matter of taste. The answer was that the criterion is gravitational energy efficiency — that which is more vertical is that which the gravitational field can support. The practitioner is not training his eye to find Roman bodies more beautiful than Greek ones; he is training it to read which arrangement of segments will let the body live within the field with less energetic loss. The line is an energetic claim, not an aesthetic one.

"That which is gravitationally energy wise efficient is one way that we express So a roper doesn't have a perception in his mind of of subjective beauty or anything less? No. No. He doesn't think they begin to think after a while that Roman bodies are beautiful. But as far as a Greek as opposed to a Roman or as opposed to some other form, you know, it's not."

A visitor asks whether the criterion is aesthetic; a practitioner answers as Ida had taught:

The exchange clarifies that the criterion behind the line is gravitational energy efficiency, not an aesthetic preference for one body shape over another.18

Ida pressed the same point against her students when she heard them describing the work too vaguely to a hypothetical client. In the 1975 Boulder class she walked through a fictitious skeptic — would you spend $350 to be brought in line with gravity? — and demanded that her students articulate why the gravitational alignment matters in mechanical terms. The line, in her hands, was not allowed to remain a piece of jargon. The student had to be able to explain that gravity acts as a constant vertical force, that a body aligned with that force is supported by it, and that a body misaligned is broken down by it. Without the mechanical chain, the doctrine of the line is sales pitch.

"What he said was always as far as it went, but he didn't go far enough. Gravity acts in gravity is like an energy field with a constant energy that acts It isn't like an energy field. I think it is an energy field. It's Alright. It's alright. What I'm gonna say is not exactly what it is, but it's for all practical purposes. Alright. I had no business in the beginning. It's a energy field that acts with a constant force vertical to the plane of the earth. And so that when we move through space and we're not vertical, or we are vertical, then gravity actually helps us move through space if we are in line with this field? Gravity acts supportively Gravity acts if it is able to do so. And our job, as I have told you at least six times in this class, is to get it get our bodies so that they are they can be supported by gravity."

Pressing her Boulder students to explain the line mechanically, she supplies the missing link:

She insists the practitioner has to be able to convert the vague phrase 'in line with gravity' into a mechanical claim about gravity acting supportively on a vertical body and breaking down a random one.19

The body as a plastic medium — why the line can be built

The reason a practitioner can build a body around the line is that the body, by Ida's account, is a plastic medium. She used the word in its technical sense — a substance that can be deformed by pressure and brought back into a different stable shape, so long as its elasticity is not exceeded. In the 1974 Healing Arts lecture she defined plastic deformation specifically in terms of the line. Back to shape, for her, did not mean back to whatever shape the body happened to be in before. It meant back to the shape that vertical alignment with the earth's field describes — the shape the body would have if its history had not deformed it.

"body is a plastic medium, and you're going to hear that several times before we get out of here today. Now, we are ready to define rolfing structural integration. It is a system of organizing the body so that it is substantially vertical, substantially balanced around a vertical in order to allow the body to accept support from the gravitational energy. Two characteristic qualities of the body make this unlikely situation possible. The material body of man is a plastic medium, as I just told you. Now by dictionary definition, a plastic substance is one which can be distorted by pressure and then can, by suitable means, be brought back to shape, providing that its elasticity has not been exceeded. Now the question is, what is back to shape in this context really mean? And the answer is simple and really expected."

In the same 1974 Healing Arts lecture, she gives her technical definition of the body as plastic:

The definition supplies the conceptual ground for everything else — the body can be brought around the line because it is a plastic medium whose back-to-shape is verticality.20

The mechanism of plastic deformation, in her account, is collagen chemistry. The myofascial body is held in its shape by the collagen molecule, a triple-helix protein whose strands are cross-linked by inorganic ions — hydrogen, sodium, calcium. The practitioner's pressure adds energy at the site, and the ionic ratios shift; the tissue becomes more resilient, more flexible, more responsive to the demand that it occupy a different relationship. The line is therefore not abstract geometry; it is the geometric description of what the collagen body looks like when its ionic budget has been re-organized by repeated applications of the practitioner's pressure in the right directions.

"Two factors contribute to this: the first that the body, seemingly a unit, is in fact not a unit but a consolidation of large segments: the head, the thorax, the pelvis, the legs. The relation of these segments can be changed because the connecting myofascial structure is a structure of connective tissue of collagen. This is what that myofascial body is about. And collagen is a unique protein. The collagen molecule is a very large protein and it is a braiding of three strands a special braiding. These three strands are connected by various inorganic hydrogen sometimes, sodium sometimes, calcium sometimes, and undoubtedly other minerals. These minerals are interchangeable within limits. Thus, as the body grows older and stiffer, undoubtedly a larger percentage of calcium and a smaller percentage of sodium are present in these bonds. But by the addition of energy and what is energy? In this come in this context, it can it is the pressure of the fingers or the elbow of the ralpha. This ratio may be varied by the addition of this energy, and the joint or the connective tissue becomes more resilient, more flexible."

She continues, walking from the body-as-plastic claim into the chemistry that supports it:

The passage names the molecular mechanism — collagen, ionic crosslinks, energy added as pressure — that lets the practitioner change the relationships the line describes.21

The line as an open-ended goal

Although she insisted on the precision of the line as a target, Ida was equally insistent that no body ever finally arrives at it. On the RolfA6 public tape she described the line as an open-ended goal — a goal a living biological system moves toward but never closes on, because life itself is not a closed-end condition. The work continues to move toward the line as long as the body lives. There is no terminal state at which the practitioner can declare a body finished. The line is asymptotic. What changes after ten hours of good work is the body's relationship to the line, not its arrival at it.

"And as you get that body oriented into those three-dimensional lines, you have this gold point which we've been for which we've been reaching out. Now you have to remember that you never get a closed end goal. There is no such thing in a living biological system as a closed end goal. Soon as you get sunset somewhere, something else starts happening. Some other adjustment starts occurring. Some other change comes. Now that isn't anything else. It's the normal procedure of aging, and I do not mean the abnormal procedure of falling apart. So you see, you always have that open ended goal in front of your eyes, your mind's eyes, and you're always moving toward it. And you never really get to it and really latch onto it forever and ever if life isn't that way. You talk about symmetry in the body."

On the RolfA6 public tape she names the line as a target that recedes:

She names the line as an open-ended goal, an asymptote rather than a destination — an important corrective against the idea that ten hours of work produces a finished body.22

The same passage carried a second teaching. The lines of the body are not only vertical. They include horizontals where the spine must function as an upended beam rather than a column, and where adjustments at the major junctions allow the segments above to balance the segments below. The line is therefore a composite — a vertical with horizontal cross-references at each major hinge — and the practitioner's job is to bring each junction into the relationship that lets the line, in its compound form, run through the body. Symmetry has to be built in a body whose internal organs are themselves not symmetrical; the line is the geometric ideal the asymmetric body approaches.

"have got a degree of balance in that body now that permits a vertical line to come up through the ankles, through the knees, through the hips, through the bodies of the lumbars, through the shoulders, through the ears. Have you all got this picture of progression? Because this is the message of the morning. This progression that a human being is getting from a wad of stuff that's slopping all over the place to a form, a precise form, which acts as though it were built around the line. You remember the story that I told you earlier about has about Claude Bernard, who in getting his citation for the Legion of Honor said, Gentlemen, a man is a something built around a gut, because he was the guy that studied guts. But if we ever happen to get a bleach in the monor decoration, we're going to have to say something else. We're going to have to say, gentlemen and ladies, a man is a something that is built around a line. But figure what would happen if he were really built around the line and standing on that relative point of the ankles."

In her August 1974 IPR lecture she described the line as a series of segments with junctions for adjustment:

She qualifies the simple vertical-line picture by naming the junctions where the segments must break and balance — a more realistic structural description of how the line actually runs through a body.23

The line and the energy field

By the mid-1970s Ida had begun to talk about the line not only in mechanical terms but in terms of what Valerie Hunt was measuring at UCLA. The body, in this later framing, has its own energy field around it, and that field can be coherent or incoherent. A body whose vertical coincides with the earth's vertical produces a more coherent field; a body whose vertical is at odds with the earth's produces a fragmented one. The auric measurements Hunt had taken — average half-inch to inch widths in random bodies, expanding to four or five inches after the work — were presented as evidence that the structural change registers at the energetic level as well as the mechanical.

"has found, for example, and will tell you about it, that random incoming people tend to have auras a half an inch to an inch in width, but after the integration of structure and the integration of the myofascial body, which is called rolfing, their auras will have increased usually to four to five inches in width. That's what we said. Wow! Obviously, we are dealing with a basic energy phenomenon of life here. Whether this really relates to or equates with the energy referred to earlier, the energy whose principal distinguishing characteristics is its failure to observe the law of inverse squares, which characterizes Newtonian energy transmission. This we do not know at this point, nor do we see any way to determine it in the very near future. But that which we do know is exciting enough. What do we know?"

Opening her 1974 Healing Arts lecture, she names the energy claim that became the late framing of the line:

She names Hunt's auric findings as evidence that the structural alignment around the vertical line affects the body's energy field at a measurable level.24

The energetic framing changed how Ida talked about the line's purpose in the late teaching. The line is no longer described primarily as the geometry of mechanical efficiency; it is described as the condition in which the body's energy field can resonate with the earth's. Whether the field is read aurically, electromyographically, or simply in terms of the man's reported sense of vitality, the line is the position in which the body becomes a transducer of the gravitational energy rather than an obstacle to it. This is the framing she carried into the 1976 advanced class and into her final public presentations.

"And this is indicative merely of the fact that we are going into an unknown territory, a terra incognita, and trying to find out what changes in that body are going to develop into what changes in the personality that calls itself the owner of that body. And I'm talking here about energy being added by pressure to the fascia, the organ of structure, to change the relation of the fascial sheaths of the body, to balance these around a vertical line which parallels the gravity line. Thus, we are able to balance body masses, to order them, to order them within a space. The contour of the body changes, the objective feeling of the body to searching hands changes. Movement behavior changes as the body incorporates more and more order. The first balance of the body is a static stacking, but as the body incorporates more changes, the balance ceases to be a static balance. It becomes a dynamic balance. These are the physical manifestations of the increasing balance, but there is an outgoing psychological change as well toward balance, toward serenity, toward a more whole person. The whole man, the whole person evidences a more apparent, a more potent psychic development. This means that the rate that the ratio man energy to gravity energy energy has changed has increased. The ratio has therefore increased the force available to reverse the entropic deterioration. That is and greater. Our world is no longer running down. It seems capable now of building up."

On the CFHA tape from 1974 she draws out the consequences of balancing fascial sheaths around the vertical:

She links the structural change — balancing fascial sheaths around the vertical — to the downstream consequences in contour, movement, and what she called the ratio of man energy to gravity energy.25

The lumbar as the structural giving-point

In a 1971-72 Mystery Tape session Ida pressed her students on a structural detail that complicates the simple vertical-line picture. The lumbar curve, she said, is the point in the spine that gives — that can move forward, occasionally backward, in response to the body's history. The thoracic vertebrae cannot give in the same way without compromising the cardiovascular structures they enclose. So when a body has been distorted by history, the lumbar is where the distortion shows; and when the body is brought around the line, the lumbar is the place where the alignment registers first. She told the class that an osteopath who knew how to look could see the lumbar change in the first hour of the work.

"Now, Fox is talking from the point of view of the spine. If we ever get to be great big boys and girls that sit in the Council of the Mighty's, it will be because we do not use that entry, but because we use an entry which is more acceptable to modern thinking. Every time a chiropractor talks about a spine, a medic hears him say that the trouble is because the vertebrae are too close and not pinching a If they're intelligent, open people, they listen and they don't slam the door in your face. Now I don't know what this says. It only says, I'm just not kicking this way around. And I recommend it to you. But I also recommend that you look as to why this is the way it is. And this story that I have just told you about the fact that the lumbar lever is going to be the one that can adjust, is going to be the one that has to adjust to the structural demands of any body, It has, something has to give and it can give. The dossiers can't give."

In a 1971-72 Mystery Tape session she describes the lumbar as the structural giving-point:

She names the lumbar curve as the one part of the spine that can structurally give — making it both the locus of distortion and the place where re-alignment around the line first registers.26

The teaching has a consequence for how the line is built across the recipe. Every hour of the work that brings the segments above and below into a more vertical relationship will register at the lumbar — either as an exaggeration of the existing curve, if the work has been done badly, or as a reduction of it, if the work has been done well. The lumbar is the practitioner's diagnostic instrument. Ida used the metaphor of structural give: the rest of the spine resists deformation, but the lumbar accepts it, and what is accepted there is what tells the practitioner whether the body is moving toward the line.

Reading the eyes — where the line lives in space

By 1976 Ida's senior teachers had begun to articulate aspects of the line that lay beyond mechanics. In a teachers' class one of them — addressing how a body finds and holds its new alignment — described the eyes as among the most important indicators of where a person is in space. A client whose structure has been brought around the line will still, for a time, see the world from the eye-height they used to have, and that visual memory will pull them back into the old structure unless the practitioner explicitly cues the new orientation. The line, in this teaching, is not held only by tissue. It is held by the body's whole orientation system, including vision.

"For each one of these rotations or shifts up in here, it is expressed with what is going on right down as the leg spins into the pelvis. So this is why it's so important to look at where you're cuing a person at the end of an hour because they have a recording which let me add another thing for you to think about. The eyes to me are one of the most important indicators of where a person is in space. If they walk into the room and this is vertical to them where my eye level is, you may work on them and they have the capacity to be there. But their eyes tell them in the height of the room that, one, they are only this high when they stand upright, and two, they are back here, and you take them here, that's a whole new orientation. So you've got to tell them it's all right to let their eyes play tricks on them just for a moment until they take that space or maybe ask them to close their eyes while you help them find that. Ask them to open their eyes and then, you know, take a sense of where they are. I cannot tell you how often happens. It's the eyes."

In a 1976 teachers' class a senior teacher names the eyes as a determinant of where the line gets held:

The passage extends the line beyond tissue mechanics into the body's whole spatial-orientation system — the eyes have to be reprogrammed for the new alignment to hold.27

This was a refinement of the line's doctrine that Ida did not articulate in this form in the earlier classes, but which her senior teachers had begun to develop in dialogue with her. The line lives not only in the body's segments but in the body's relationship to the space around it. The eyes register that relationship; so do the inner-ear, the proprioceptive system, the felt sense of where the head sits over the shoulders. The work of structural change has to be coordinated with the work of perceptual re-orientation, or the body will return to its previous arrangement. The line is a settled relationship between a body and the space it inhabits.

Naming the work for the public

In a 1974 lecture preserved on the Structure Lectures tape, the introducer placed Ida's biography in front of the audience: born in New York in 1896, a PhD from Barnard College in 1916 as a research chemist, hired immediately afterward by the Rockefeller Institute, sent to Europe in the late 1920s where she sat in on lectures by Erwin Schrödinger at Zurich. That European exposure, the introducer noted, was the genesis of the idea that there was a direct relationship between human behavior and both body physics and body chemistry. The line, in its mature form, was the geometric expression of that relationship — the place where physics, chemistry, and behavior meet.

"Rolfing has now become a world renowned system for changing the structure of the body so that it is virtually aligned with the force of gravity. Rolf was born, raised, and educated in New York City. She received her PhD in 1916 from Barnard College as a research chemist. Now at that particular time, few American women sought degrees as research scientists and still fewer were given employment in research institutions. Ida Rolf was immediately hired by the Rockefeller Institute. In the late 1920s, Doctor. Rolfe was sent to Europe by the Institute, and it was during that time that she sat in on some lectures of Erwin Scheddinger at the University in Zurich. She began to suspect that there was a direct relationship between human behavior and both body physics and body chemistry. This was the genesis of the idea of structural integration."

The 1974 Structure Lectures introducer names the biographical origin of the line as a structural idea:

The passage anchors the line in Ida's biographical sources — the Rockefeller training, the Zurich exposure to Schrödinger — and names the question that her work was built to answer.28

Ida herself, in the same lecture, took up the task of speaking about the work and warned her audience that any verbal account is necessarily a hint. The work is experiential before it is conceptual. The line can be named, drawn, measured, defended in a mechanical chain — but what the line is, in the body of someone who has received the work, is felt before it is articulated. Her insistence that the line be built rather than merely measured had this practical correlate: the body knows the line before the mind does, and the practitioner's job is to bring the body into the felt condition first. The verbal account is a hint about a country one has to enter through the tissue.

Coda: the line as the map of the work

On the RolfA6 public tape Ida gave what may be the cleanest summary of how the line functions inside the practitioner's mind. The line, she said, is the map that directs the entire activity of the work. Everything the practitioner does — the sequence of the ten hours, the choice of which structure to work next, the decision of when to stop in a given session — is governed by the question of how to bring the body further into a relationship with the three-dimensional lines that define the space the body lives in. The line is not a result the practitioner is producing; it is the orientation against which every decision is made.

"Oh, Now that line situation we started to work with the other day, and I think we'll continue to work with that a little bit right now. As you might imagine, in fact, you were working with that a little bit this morning when you were looking at this whole thing. Because you see that line situation really is the map which directs your entire activity in this work. You are making it possible. You are doing the changes or establishing the changes which make possible for the human being to be built around and to operate around this set of lines which determine the three-dimensional space that we live in."

On the RolfA6 tape she names the line as the directing map of the practitioner's work:

She converts the line from a measurement at the end of the work into the orientation at the beginning of every decision — the map, not the destination.29

What stays in the practitioner's hands at the end is not the line itself but the body's improved capacity to live near it. The man stands more nearly vertical; gravity supports rather than wears him; his energy field, in Hunt's measurements, registers more coherence. The line has not been achieved in any absolute sense — Ida was clear that no living body achieves it absolutely — but it has been approached. The work has done what she said no other school could do: it has not merely measured the verticality the schools share as a standard, it has built a body around it. This was the claim she defended across every classroom from Big Sur to Boulder to New Jersey, and it is what every other doctrine in her teaching — fascia, the recipe, the segments, the energetic field — was organized to make possible.

1 Defining Rolfing Structural Integration 1974 · Healing Arts — Rolf Adv 1974at 39:12

Ida defines the vertical line as a set of anatomical registrations — ankles, knees, hip joints, lumbar vertebral bodies, shoulders, ears — that must align if the body's energy field is to be balanced around the gravity vertical. The passage comes from her 1974 Healing Arts conference lecture and stands as her most concise statement of what the line actually measures.

2 Defining Rolfing Structural Integration 1974 · Healing Arts — Rolf Adv 1974at 39:24

Ida acknowledges that every accepted school of body mechanics teaches the vertical as a measuring stick, with the Harvard group at the head of the list. What distinguishes her work, she says, is that no other school teaches how to achieve it. The claim rests on the body being a plastic medium — a statement she notes would have gotten her institutionalized fifty years earlier.

3 Balance, Structure, and Posture various · Soundbytes (short clips)at 36:25

Ida insists that posture is what you do with structure and structure is the way you relate the parts of the body to each other. The passage closes a longer disquisition on the difference between the placed (posture) and the related (structure), and she explicitly asks her listeners to meditate on the two words before going further.

4 Balance, Structure, and Posture various · Soundbytes (short clips)at 35:28

In the Topanga lecture, Ida reads the effortful posture as a sign that the man is losing his fight with gravity. Where structure is in balance, posture is automatically good; where structure has failed, posture becomes a continuous expenditure of effort. This converts the line from an aesthetic goal into a diagnostic instrument.

5 Defining Rolfing Structural Integration 1974 · Healing Arts — Rolf Adv 1974at 42:20

Ida explains that 'back to shape' in her work means vertical — vertical to the surface of the earth, like the burrows of the chestnut, like the force of gravity. Only when the body's gravity vertical coincides with the earth's gravity line can the earth's energy field reinforce and augment the body's. Gravity then becomes the nourishing medium, and the body becomes vitalized. This is the energetic doctrine that underwrites the structural one.

6 Scientific Validation at UCLA 1974 · Open Universe Classat 11:15

Valerie Hunt describes her pilot work at UCLA: as a person approximates the vertical — ears over shoulders, shoulders over hips, hips over knees, knees over ankles — significant changes occur in neuromuscular behavior that can be recorded by electromyographic and electroencephalographic measurement. Hunt's framing converts Ida's energetic doctrine into a research program.

7 Tenth Hour: Establishing Horizontals 1971-72 · Mystery Tapes — CD1at 29:30

Ida tells her students that the horizontal line is the index — the outward and visible sign, in the words of the good old catechism, of the inward and spiritual grace. The vertical itself is not directly observable; the horizontal hinges of the body register it. This is the operational principle that lets a practitioner read a body's relationship to the line by looking at what is visible.

8 Tenth Hour: Establishing Horizontals 1971-72 · Mystery Tapes — CD1at 32:55

Ida distinguishes her notion of balance from the various competing balances of osteopathy, chiropractic, and classical sculpture. Her horizontal emerges out of three specific practical claims — knees moving forward, elbows moving outward, hips moving upward — interacting in the body. Without these specific movements, what one is calling balance is only a theoretical position.

9 Experiencing the Centerline 1976 · Rolf Advanced Class 1976at 45:39

Ida runs an experiential demonstration in her 1976 advanced class. Standing in place, the students shift weight onto the outer arch and feel the loss of the center line. Her diagnostic phrase — you lose your line, you are no longer a unit — names the line not as a geometric construct but as the felt condition of internal coherence.

10 Experiencing the Centerline 1976 · Rolf Advanced Class 1976at 46:21

Ida instructs that the center line connects down the inside of the leg, and that weight falling on the outer arch destroys it. Turning the toes up begins to put the weight back into the center line. The passage corrects what she heard her students quoting from books — that weight should fall through the three center toes — and reasserts the experiential evidence.

11 Introduction and Growth Premise various · Soundbytes (short clips)at 0:00

Ida describes the practitioner's first task as visualizing the person in front of them as a set of blocks — how they currently stack, how they should stack, what would need to change to bring them into vertical alignment. The story is what the work is about, even though the how-to of doing it is much more complicated than the picture suggests.

12 Collagen and Connective Tissue 1973 · Big Sur Advanced Class 1973at 10:50

Ida tells her Big Sur students that the body's various organ systems contribute energy as an algebraic sum — some plus, some minus. Well-stacked blocks give maximum efficiency; as the blocks become unstacked, efficiency falls. The image translates the structural claim about the line into an energetic claim about how a body lives.

13 Training and the Rolfed Ideal 1974 · Open Universe Classat 27:40

A practitioner teaching at the Open Universe class names the goal of each hour as horizontalizing the pelvis — the bowl spills forward in most people, and the work brings it back to a horizontal plane so the torso's contents sit in it properly. The framing parallels Ida's own and shows how her pelvic doctrine had become the standard public-facing introduction.

14 Floor of the Pelvis Emphasis 1975 · Rolf Advanced Class 1975 — Boulderat 4:42

Ida tells her Boulder students that when they talk about the pelvis they are really talking about the floor of the pelvis, and that the fifth hour's goal is the horizontalizing of that floor. The refinement matters because the floor, not the bony rim, is the structural horizontal that the legs support and the torso balances on.

15 Three Primary Manifestations of Disease 1975 · Rolf Advanced Class 1975 — Boulderat 0:18

A senior practitioner in Boulder reports Ida's teaching that the first hour is the beginning of the tenth, the second hour is the second half of the first, and the third hour is the continuation of both. The ten-session breakdown was a practical concession to what the body could absorb in a session, not a conceptual partition. The line is built cumulatively.

16 Second Hour Review and Structure various · RolfB3 — Public Tapeat 0:26

Ida describes the second hour as a putting of support on the pelvis and a lengthening of the back so that the trunk can balance over the pelvis. She frames the whole series as iterative passes at the same problem — getting the body balanced within the gravitational field so that gravity has no moment of rotation by which to break it down. The line is the abstract description of that condition.

17 Defining the Fifth Hour 1975 · Rolf Advanced Class 1975 — Boulderat 3:39

Steve Weatherwax tells the Boulder class that since the first hour the work has been horizontalizing the pelvis. The chest has been lifted, the back lengthened, the sides opened, and a midline begun. Now the front needs to be lengthened to bring the pelvis up anteriorly. Ida compliments him on the answer and adds the further key: the fifth hour has to do with the floor of the pelvis.

18 Training and the Rolfed Ideal 1974 · Open Universe Classat 1:03

A visitor to the Open Universe class asks whether the criterion of Structural Integration is aesthetic. The practitioner answers that the criterion is balance and alignment within the gravitational field — that which is gravitationally energy-efficient is the goal. The exchange shows how Ida's practitioners had learned to deflect the aesthetic reading.

19 Students Resistant to Vertical Concept 1975 · Rolf Advanced Class 1975 — Boulderat 1:25

Ida demands that her students articulate gravity as a vertical energy field acting with a constant force on every body. A body aligned with the field is supported by it; a body misaligned is broken down by it. Without this mechanical chain, the doctrine of alignment with gravity remains a piece of unconvincing jargon.

20 Introductions of Hunt and Rolf 1974 · Healing Arts — Rolf Adv 1974at 0:00

Ida defines Structural Integration as a system of organizing the body so that it is substantially vertical, balanced around a vertical in order to accept support from the gravitational energy. The body's plasticity — its capacity to be distorted by pressure and brought back to shape — is what makes the unlikely situation possible, where 'back to shape' means vertical.

21 The Body as Plastic Medium 1974 · Healing Arts — Rolf Adv 1974at 43:57

Ida walks from the segmented-body claim into the chemistry of collagen: the myofascial body is held by a triple-helix protein cross-linked by inorganic ions, and the practitioner's pressure adds energy that shifts the ionic ratios and makes the tissue more flexible. The mechanism explains why the line can be built rather than merely measured.

22 The Line and Open-Ended Goals various · RolfA6 — Public Tapeat 42:00

Ida insists there is no closed-end goal in a living biological system. The line is a target the body moves toward, but never finally reaches; the work continues, the body continues to age, and the line remains the direction of travel rather than the destination. The practitioner who imagines arrival at the line has misunderstood what the line is for.

23 Introductions and Class Opening 1974 · IPR Lecture — Aug 5, 1974at 0:00

Ida described in her August 1974 IPR lecture how a degree of balance in the body now permits the vertical line to come up through ankles, knees, hips, the lumbar bodies, shoulders, and ears. But she immediately complicates the picture: a body built strictly around a line would be impractical, so the line must be broken into segments at major junctions where one piece of anatomy balances another. The line, in its compound form, runs through these adjustments.

24 Introductions of Hunt and Rolf 1974 · Healing Arts — Rolf Adv 1974at 0:00

Ida opens her 1974 Healing Arts lecture by reporting Valerie Hunt's findings: random incoming people tend to have auras a half-inch to an inch wide, and after the integration of structure the auras expand to four or five inches. She frames this as evidence that the work is dealing with a basic energy phenomenon of life, and that the energy fields of the body must be substantially balanced around the vertical line for gravity to act supportively.

25 Balancing the Body in Gravity 1974 · Healing Arts — Rolf Adv 1974at 5:25

Ida describes adding energy by pressure to the fascia, the organ of structure, to change the relation of fascial sheaths and balance them around a vertical line that parallels the gravity line. The contour changes; the objective feel of the body changes; movement changes; and the ratio of man-energy to gravity-energy increases. The line is the geometric description of the condition that makes these downstream changes possible.

26 Pathology as Distorted Physiology 1971-72 · Mystery Tapes — CD1at 16:57

Ida tells her students that the lumbar curve is the structural giving-point of the spine. It can move forward, occasionally backward, in response to the body's history. The thoracic vertebrae cannot give the same way without compromising cardiovascular structures. The lumbar is therefore where distortion shows and where alignment around the line first registers. An osteopath who knows how to look can see it change in the first hour.

27 Tibia/Fibula Rotation and Eye Orientation 1976 · Teachers' Class 02at 45:25

A senior teacher tells the 1976 teachers' class that the eyes are one of the most important indicators of where a person is in space. After the work has brought a body into a new alignment, the eyes still recall the old eye-height, and that visual memory pulls the body back. The practitioner has to give the client permission to let the eyes find the new space, or close them and re-orient. The line is held by orientation, not only by tissue.

28 Introduction of Dr. Ida Rolf 1974 · Structure Lectures — Rolf Adv 1974at 0:19

The introducer to a 1974 Structure Lectures session names the genesis of Structural Integration: Ida's PhD from Barnard in 1916 as a research chemist, her hiring by the Rockefeller Institute, and her exposure in the late 1920s to Erwin Schrödinger's lectures at Zurich. From those lectures she began to suspect a direct relationship between human behavior and both body physics and body chemistry. The line is the geometric expression of that relationship.

29 The Line and Open-Ended Goals various · RolfA6 — Public Tapeat 40:42

Ida tells her listeners that the line situation is the map that directs the entire activity of the work. The practitioner is establishing the changes that make it possible for the human being to be built around and to operate around the three-dimensional set of lines that define the space we live in. As the body orients into those lines, the open-ended goal toward which the work has been reaching comes into view.
