Gravity as a field, not a metaphor
Ida came at gravity with the vocabulary of a Barnard-trained chemist who had spent the 1920s sitting in Erwin Schrödinger's Zurich lectures. When she said gravity, she did not mean the homely fact that things fall down. She meant a field — a continuous, directional energy that either flows through a body and reinforces it or piles up against the body and breaks it. The distinction matters because every other school of body mechanics she encountered treated verticality as a posture to be held against gravity. Ida's claim was the opposite: verticality is the only condition under which a body stops fighting gravity and begins to be fed by it. The practitioner's job, then, is not to instruct the body to stand up straight. It is to alter the structure until the field can do its own work. In her 1974 Healing Arts lecture, she laid this out in nearly thermodynamic terms.
"We know that order can be evoked in the myofascial system of the body by substantially balancing the myofascial structures about a vertical line. We know that logically in body mechanics, we can expect that the vertical lines of that force manifesting as the gravitational field can either support and reinforce a body, or it can disorganize it and presumably passing by presumably passing through and being part of it, it can destroy and minimize the energy fields surrounding it."
From the 1974 advanced class at Healing Arts in California, Ida states the operative law:
Notice what Ida does in that passage. She makes gravity an agent — something that can support, reinforce, disorganize, destroy. And she makes the body's alignment the variable that determines which verb gravity executes. This is the move that licenses everything she will go on to say about demand. If gravity were a passive constant, the practitioner's only option would be to instruct the client in better habits. But because gravity is an active field whose effect changes with the structure it passes through, the practitioner can manipulate that structure — and the field, doing its own work, will reward or punish the result. The work is not pedagogy of the will. It is engineering of the relationship between a plastic body and a constant field.
Symmetry around the line
If gravity is going to do the work, gravity needs something to grab. In the 1976 Boulder advanced class — speaking to a student who had just finished a tenth hour and was puzzling over what 'balance' actually meant in practice — Ida pressed on the geometric prerequisite. Symmetry, she said, is the practitioner's offering. You cannot ask a constant vertical force to support an asymmetrical mass and expect the force to oblige. The body has to be presented to the field in a configuration the field can use. This is where 'demand' begins to take its specific shape in her teaching: the practitioner demands of the body that it become the kind of object gravity can act on supportively. The body's job is to comply with that demand by becoming symmetrical around the vertical. The field's job is to do the rest.
"The only way that you can get gravity to work for you is to give gravity something that is relatively symmetrical around the globe."
In the 1976 Boulder advanced class, after a student had tried to describe what she was searching for in a tenth hour, Ida cut to the operative geometry:
The phrase that does the work here is 'relatively symmetrical around the globe' — a small slip of the tongue, perhaps, for the vertical axis, but it captures Ida's instinct that the body is a three-dimensional object in a three-dimensional field, and that the field meets the body all the way around. Symmetry is not a cosmetic outcome. It is the engineering precondition for gravity becoming a nourishing rather than degenerative force. And because no living body arrives at the practitioner's table already symmetrical, the practitioner has to build the symmetry. That building is what Ida means by demand.
"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."
Still in that 1974 Healing Arts lecture, she names what happens when the symmetry is achieved — gravity becomes nutritive:
The body as a plastic medium
The word demand only makes sense if the thing being demanded of is capable of changing. In the medical orthodoxy of her training, the adult body was essentially fixed — its shape determined by genetics, its alterations limited to disease and injury. Ida spent her career attacking that assumption. The body, she insisted, is plastic. The collagen of the fascia can be reorganized by the addition of energy, and the energy in question is nothing more exotic than the pressure of the practitioner's fingers and elbows. This is the second pillar under demand: not only does gravity reward symmetry, but the tissue that needs to be symmetrized is materially capable of accepting a new arrangement. In the same Big Sur 1973 lecture where she traced the rise and fall of the structural school of healing, she gave one of her clearest accounts of how added energy actually does the work.
"It's pure physics as it's taught in physics laboratories. Now the strange part about it is that that organ of structure is a very resilient and very elastic and very plastic medium. It can be changed by adding energy to it. In structural integration, one of the ways we add energy is by pressure so that the practitioner gives deliberately contributes energy to the person on whom he is working, to not energy in the sense that you let a position throw it around, but energy such as they talk about in the physics laboratory. When you press on a given point, you literally are adding energy to that which is under that point. And in structural integration, by way of an unbelievable accident of how you can change fashion structure, you can change human beings. You can change their structure and in changing their structure you are able to change their function. All of you have seen that structure determines function to a very great degree, to a degree which we can utilize."
From the 1973 Big Sur advanced class, Ida walks the students through the mechanism by which pressure becomes structural change:
Once the body is understood as a plastic medium responsive to energy input, the practitioner's hands stop being instruments of persuasion and become instruments of physics. The shift in vocabulary matters. A masseur asks the tissue to relax. A chiropractor instructs the joint to return. Ida's practitioner adds energy and demands work. The verb shift is not stylistic — it reflects a different theory of what is happening under the hands. The work is being done to a real material whose molecular bonds are being rearranged. That kind of work has no patience for begging.
"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. And it is the collagen system which basically, which the two classes on different levels are going to turn your attention to in the the next six to thirty weeks. You are going to be getting more and more intimate with collagen which before you heard it well could mean you didn't know existed. But you see, it is the connective tissue which is the organ of structure. The fascia envelopes are the organ of structure, the organ that holds the body appropriately in the three-dimensional material world. Now nobody ever taught this in the medical school as far as I know. And anytime you want to get into an argument with your medical through they'll realize that this is so."
Earlier in that same Big Sur class, she had laid out the same point in slightly different language, naming fascia as the organ of structure:

The practitioner demands physiological movement
Here the rule lands in its operational form. In the public-tape series that captured her teaching of the first hour, Ida set out the manipulative law that governs every session that follows. The practitioner brings the structure toward where it normally should occupy — not averagely should occupy, but normally, as determined by examination of the skeleton and the physiology of the joint. And then, holding the structure in that direction, the practitioner demands physiological movement. Not pleads for it, not coaxes it, not suggests it. Demands it. The breath. The reach. The flexion. The walk. The movement is what locks the structural change into the body's neuromuscular memory. Without the demand for movement, the hands have only produced a transient shift that the old pattern will reabsorb the moment the practitioner steps back.
"So that your first law, your first manipulative law, is to take the structure and bring it toward the position which it normally should occupy. And I don't say which it averagely should occupy. Which it normally should occupy, which it's designed to occupy, which an examination of the skeleton and the physiology of the in of a human say it has to occupy if it's going to work best, work most easily, work with least energy expenditure. You bring it into that direction and you demand physiological movement."
From the RolfB1 public tape, Ida states the manipulative law of the first hour:
Ida's elaboration of this point in the same public tape draws the line between her work and orthodox manipulation as sharply as she ever drew it. Other systems, she said, operate on the assumption that the practitioner can replace something that has been displaced. You can replace it, she conceded — but you cannot make it work in the new place. Only the client, through demanded movement, can do that. And here she introduced a complaint that recurs throughout her late-career teaching: clients arrive expecting to lie on the table like a sack of laundry while the practitioner does something to them. The work refuses that arrangement. The body being worked on has to participate, has to breathe, has to reach, has to walk the demanded pattern while the practitioner holds the fascia in the new direction.
"Now in working in that first hour as you worked on the thorax over and over again we said, that's right, breathe please, take another breath please. This is physiological movement for the thorax. And while you are holding that fascial sheath in the position in which or toward the position where it should be, ideally speaking, you are demanding physiological movement, in this case breath. When you get into the arms as you are holding it, as you are holding the restrictions in the upper arm, you are demanding physiological movement of the arm. And what is the physiological movement? Today you have a big motor pattern that goes out from the elbow. And the same is true with the leg, etcetera, etcetera. You cannot reorganize a body with your hands. You can only help that body to reorganize itself through movement. Now this is the basic difference in concept between what you are going into here and the other much more orthodox manipulative techniques. Their assumption is that they can replace something that has been displaced. You can, but you can't make it work there. He has to make it work there."
Continuing in the RolfB1 public tape, Ida explains why hands alone cannot finish the work:
Our job is to get the body so it can be supported by gravity
By 1975, Ida had been teaching the same fundamental doctrine for more than two decades, and her frustration with practitioners who could not explain it in plain language had reached the point of public castigation. In the 1975 Boulder advanced class, working through the fifth hour with a student practitioner who had not been at the previous night's review session, she essentially restarted the entire curriculum on the spot. She demanded that another student walk Norman through the logic of the work from zero — and then, when the student stumbled on the question of why a practitioner cares whether the body meets gravity supportively, Ida stepped in with the formulation she had been refining for years.
" 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."
In the 1975 Boulder advanced class, after a struggling student-practitioner exchange, Ida states the mission directly:
Read carefully, that line carries the whole doctrine. Gravity acts supportively only if it is able to do so. The conditional is everything. Gravity does not always support. It only supports a body it can support — meaning a body sufficiently aligned with the vertical that the field flows through rather than across it. The practitioner's task is not to make gravity behave differently; gravity is constant. The task is to alter the body until gravity's supportive action becomes possible. This is why begging is the wrong verb. You cannot beg a constant. You can only present it with a structure that lets it do what it does.
"We placed our the goal of structural integration. Goal of structural integration is to align the body structure so that it meets more efficiently with gravity. Why do you care? What do I care? Yeah. Why do you care? Why are you try why is a practitioner? Why do you care whether it meets with gravity or it doesn't meet with gravity? Well, it's it's based upon a belief that Based on more than a belief. But go on. Based on It's demonstration. That's what it's based on. Go That ahead. That a person's is better, and that to me is a belief, is better when the person's body structure is more in line with gravity. I don't understand why this should be. I'd like to be told. And that isn't merely a belief. It's a demonstration. Everybody in this room has seen it demonstrated over and over and over again. Yeah. Okay. I mean Alright. But if if the body is more in line with gravity, then our belief is that the person is more in tune with his environment."
Earlier in that same 1975 Boulder class, Ida had pushed the student-practitioner to find sharper language for what she had just stated:
Posture is what you do; structure is what you are
One of the reasons begging is the wrong verb is that begging belongs to a different model of the body entirely — the postural model, in which a person continually places themselves in the correct configuration through ongoing effort. Ida considered this a slow defeat. If a body has to be held in posture by the constant exertion of the will, then the gravitational field is being fought, not used. She made this distinction repeatedly across the public tapes, and nowhere more sharply than in the Topanga lecture, where she walked the audience through the etymology of posture itself.
"Structure, wherever you use it, is relationship, and it is particularly relationship of parts in a body. This constitutes structure. Now posture is something else again. And the boys that devised the word posture knew what that something else was because the word posture means it has been placed. It is the past participle of a Latin word, to place, and it means it has been placed. And when you use the word posture, you are saying it has been placed. Somebody has placed something somewhere. Somebody is maintaining the placement of something somewhere. Somebody is working to keep something placed somewhere. And I guarantee that there is no one in this room who doesn't know that in this day and age of the what is it? 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. Structure is the way you relate parts of the body to each other."
From the Topanga soundbyte lectures, Ida lays out the difference between posture and structure:
The verb 'losing his fight with gravity' deserves attention. It is the precise inverse of the formulation Ida used elsewhere — that gravity is the therapist, gravity does the work. The two formulations are not in tension. They name the same fact from opposite sides. If the structure is wrong, the body fights gravity and loses. If the structure is right, gravity flows through the body and supports it. The practitioner's intervention is what moves the body from the first condition to the second. The intervention is structural, not postural; it changes the relationships, not the placement. And because it is structural, it does not require ongoing effort from the client to maintain. The body, once symmetrized around the vertical, simply rests in the field.
"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. 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. Because you see, in meditating on posture and meditating on structure, you can ask the same questions. You can ask the question of, now see here, if I alter this structure, what can I hope to get from it? Similarly, you can say, if I alter this posture, what can I hope to get from it? This is a big question. And you ask any of your MD friends, and they'll say, oh, Rod, nothing. Ain't so? You change those relations. You change that structure. And you get the kind of ease and the kind of vitality that you have seen some of your friends get who have gone through this system of structural"
Still in the Topanga lecture, Ida draws the line between structural change and postural exhortation:
See also: See also: Ida's discussion of Madame Mensendieck's postural system at Yale, which she contrasted unfavorably with structural work — telling a student with a back curvature to 'stand straight' produced no change at all (RolfA — 1976 Boulder, tape 76ADV41). 76ADV41 ▸
Gravity as the therapist
If the practitioner demands structural change rather than postural compliance, and if gravity then does the work of holding the new structure, the logical conclusion is that gravity itself — not the practitioner — is the therapeutic agent. Ida arrived at this formulation by the early 1970s and repeated it across her IPR talks and the advanced classes that followed. It is the most counterintuitive of her claims for a culture that thinks of healing as something a healer does to a patient. In the IPR conference lecture preserved on the Mystery Tapes, she put the matter plainly.
"Rolfing in the sense of this deep changing of the patterns of the fundamental structure of the body to conform with gravity. I have written, as I think probably all of you know, gravity is the therapist, and this is true and I make no claim to be a therapist, but I do make a claim that says that Rothschild changes the basic web of the body so that that therapist's gravity can really get in there."
At the 1971-72 IPR conference, addressing her own practitioners, Ida explains who is actually doing the therapy:
Notice the architecture of the claim. The practitioner does not heal. Gravity heals. But gravity cannot heal a body it cannot reach — meaning a body whose fascial web has held it out of alignment with the field. So the practitioner's work is to clear the obstruction. Change the basic web so that the therapist gravity can get in. The metaphor is plumbing more than medicine: the field is the water supply, the practitioner is the plumber unblocking the pipe, and the body is the system that gets watered once the obstruction is cleared. Demand is the verb that fits this picture. You demand of the tissue that it move out of the way. You do not beg the water to flow uphill against a blockage.
"We're just as over proud of ourselves as the medics, but we are using gravity as our field, not chemistry. Now when you come to look at it, this is quite an idea because gravity is always there. You will never escape from it. From the day that single cell is fertilized and develops, gravity is with it. The fetus in the womb of the woman is under the effect of gravity. Nobody has ever looked at that and said, What can we do with this situation? This is what you people are looking at. This is what you people are working with. This is what you people must see and I mean see in a literal sense. Not a metaphorical one. You must see it metaphorical too. But you must see it literally as you begin to look at people. And they come to you with their aches and their pains, and you look at them, and you see where they are literally offering blocks to the gravitational force. And the gravitational force is immense. And their block isn't much good except to close them out of the picture. How did they get those blocks?"
In her 1973 Big Sur advanced class, Ida expands on what makes gravity the right tool:

What it means to take a body apart
The opposite of demand, in Ida's teaching, is not exactly begging — it is what she called taking a body apart. Any practitioner can put their hands in a body and produce change. The change can be unhappy, can leave the body more disorganized than before, can shift strain from one region to another without resolving anything. The discipline of demand is what distinguishes Structural Integration from random manipulation. The practitioner demands physiological movement because demanded movement is what consolidates the structural change into a new functional pattern. Without that demand, the hands are merely disturbing tissue. In the RolfB1 public tape, Ida named this danger directly.
"In fact, it's a lot easier than it is to put it together. But the reason you call yourself a worker in structural integration is because you put it together. And if you don't put it together, you're not you're doing something else. You're not doing what is being taught here. It's very, very important into the direction, the muscles, the units, whatever unit you're dealing with, toward the place that is the place where normally it was designed to work. Because the problems in bodies arise because units of that of that body, organizations within that body, get out, get away from the place where the design calls for their working. And it doesn't require a great deal of outness. An eighth of an angel do it."
From the RolfB1 public tape, Ida warns her students about the difference between change and integration:
The distinction Ida draws here is the same one she returns to in her late-career laments about practitioner skill. Plenty of her trained practitioners could produce change, she said. The number who could put a body back together was very small. The shortfall, in her diagnosis, was that the practitioners had learned the manipulations but not the demand — they had learned to disturb the fascia but not to insist on the physiological movement that locked the disturbance into a new integrated pattern. The work, she repeated, is synthetic integration. Analysis takes apart; synthesis puts back together. The verb that drives synthesis is demand.
"And before the method can be taught replication must be possible. You all remember, I'm sure, hearing me the wail, the shortcomings of Rolfers. Don't think any of you have any doubts about that. You've all heard me scream and wail, you all can take a body apart, but the number of people who can get it together are very few. The number of people who can put it together are very few. Here I was saying the same thing you see, analysis is a necessity, a cover form, a preliminary of synthesis, of conscious synthesis, of conscious integration."
At the 1971-72 IPR conference, Ida reflected on the recurring failure of her students to integrate after they had successfully disturbed:
Energy added, structure changed
Throughout her late teaching Ida kept returning to the molecular substrate of the work because she wanted her practitioners to understand that demand was not a coaching attitude — it was an energetic transaction. The practitioner's pressure adds energy to the collagen of the fascia. The collagen's bonds, which include exchangeable mineral ions, become more flexible. The tissue accepts a new arrangement. The new arrangement, demanded by simultaneous physiological movement, becomes the body's working pattern. This whole sequence is a physical process measurable in physics-laboratory terms — and it is the chemistry that authorizes the practitioner to demand rather than beg.
"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."
From the 1974 Healing Arts series, Ida traces the full sequence from pressure to balance to dynamic order:
What is striking about that account is the sequence's continuity. Pressure adds energy; energy frees the fascial sheaths; the sheaths rebalance around the vertical; balance becomes dynamic; the body's overall energetic state shifts from entropic to anti-entropic. There is no step in that sequence where the practitioner pleads with the body to comply. Each step follows mechanically from the one before, given the demand for movement that holds the new pattern in place. This is what makes 'demand, don't beg' a coherent operational instruction rather than a rhetorical flourish. It names the verb that fits the physics.
"If the muscle or the fascia has moved off its appropriate position, precise position, you bring it back toward that position and then you demand that it that it worked because hands will never do the job. Now I cannot underscore that too much because every masseur, every chiropractor, every osteopath thinks that by manipulation, he can do some job. I'm not going to say at this moment cure, though some most of them don't really believe they can cure, and god knows they can't by that method. But it is only through the work, the literal work, the literal movement of the individual concerned that you get appropriate rebalancing of those muscles. You help the individual. You do not, and you cannot do it. Now is there anybody in this room that doesn't hear? Because this is an extremely important concept. And this is is the thing that takes this work out from the group of real therapies. I don't call this a therapy. I call this a development. I call it an education, an a leading out, an evolution. Anything you like, but not healing, not therapy."
In the RolfB2 public tape, Ida specifies what the practitioner does — and refuses to do — with the freed muscle:
The body that adds is the body that does not need begging
There is one more way to hear the rule. Ida sometimes spoke of the body as a stack of energy machines — liver, lung, gut, muscle — each one either contributing or subtracting from the body's total available energy. The algebra is unsentimental. A liver functioning poorly drains energy from the rest. A pelvis out of relationship with the rib cage drains energy from every step. The practitioner's work, by symmetrizing the structure around the vertical, brings the energy machines into a configuration where each contributes rather than subtracts. When the addition has been done properly, the body has enough surplus energy to integrate the new pattern without flagging. This is the energetic argument for demand: only a body with surplus can comply with demanded movement, and the practitioner's job is to generate that surplus by stacking the blocks correctly.
"If you've got a liver structure that's functioning very badly, the rest of your body which might be doing reasonably well, you are taking away the energy from it to keep that liver going and the answer is you don't feel so well. Because what you are registering when you say I feel is the sum total of that energy. But remember that sum total is an algebraic sum. 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. And it is the collagen system which basically, which the two classes on different levels are going to turn your attention to in the the next six to thirty weeks."
From the 1973 Big Sur class, Ida lays out the algebra of energy machines:
The picture Ida draws is uncompromising. A body that does not add cannot be begged into adding. It can only be reorganized so that the conditions for adding are restored. Until those conditions are restored, the practitioner's words have nothing to land on — there is no surplus energy with which the body could comply with a postural instruction. So the practitioner does not begin with words. The practitioner begins with hands on collagen, energy added, structure changed, movement demanded. The words come later, after the surplus has been generated and the body can finally hear them.
"Know that each horizontal that you bring out down below reflects itself upward as we saw in Takashi yesterday where he's working on his leg and you can see his rib cage absorbing the change. I mean this, when the tissue is in tension, that's stored energy that you release into the body. And its energy is not a metaphysical something. These molecules are aligned in a particular way. You change their alignment. The change spreads."
In the 1975 Boulder class, a senior student summarized the same energetic principle in his own words:
See also: See also: Ida's RolfA3 public-tape exchange on the body as a plastic medium, where she affirms a student's formulation that the muscles must be freed to function as motor components rather than as structural ones — only then can demanded movement land (RolfA3Side2). RolfA3Side2 ▸
See also: See also: the RolfB3 public-tape lecture on the energetic mechanics of the joint as lever, spring, and dashpot, where the case for resonant rather than dissipative energy flow underwrites the same demand-based logic in physics-laboratory terms (RolfB3Side1). RolfB3Side1 ▸
See also: See also: the 1974 Open Universe discussion with an engineer on gravity, acceleration, and the compressive and tensile forces that keep the body upright — a sustained working-out of why Ida's claims about gravity as a field are physically coherent (UNI_054). UNI_054 ▸
Coda: why demand is the practitioner's discipline
By the time Ida had been teaching for half a century, the rule had taken its mature form. Demand is not a personality trait of the practitioner — it is the verb that fits the physics of what the work does. Gravity is a constant force acting on a plastic body whose collagen bonds can be rearranged by added energy. The practitioner adds energy by pressure, demands physiological movement to consolidate the rearrangement, and steps back to let gravity — the actual therapist — feed and stabilize the new structure. Begging has no place in this sequence because nothing in the sequence can be begged. The collagen does not negotiate. The field does not negotiate. The practitioner who tries to coax the tissue is misunderstanding what manipulation actually is.
"And only now, this is coming up again, And And I am saying to you, and I don't get to how many people say this, that we have a more fundamental way, a more basic way of dealing with structure Now the reason we have this way is because we have become sufficiently sophisticated to understand that structure is determined by the relationship of the individual body to the gravitational field. This is what often has offered in addition to any other school. What's the difference between this and this? Is the answer. We are the only group who recognize that in order for a living body to be at ease in its spatial environment on the earth, it must deal positively with gravity or rather gravity must deal positively with it. Because what we here in Lawton are here to do, we can't change the gravitational field. This is odd, but we just have nothing that means yet. But what we can do is to change the way the parts of the body that I have already referred to, how they fit together into a whole which can transmit the gravitational field. And in its energy, which is the energy of the earth, in its transmitting of that, it enhances its own energy field. You can change the body by virtue of the fact that its segments are segments of a whole and then the gravity can flow through. Now this is the basic concept of Rolfe."
Closing the 1973 Big Sur lecture, Ida names what her practitioners are doing that no other school has done:
And so the rule, in its final form, is simpler than its theoretical foundation. Bring the structure toward where it normally should occupy. Add energy by pressure. Demand physiological movement. Step back. Let gravity, the actual therapist, do what gravity has been waiting to do since the body was fertilized in a womb whose every cell was already under the field. The practitioner's discipline is not enthusiasm. It is not coaching. It is not coaxing. It is the steady insistence that the body become the kind of structure the field can use. That insistence is what Ida meant by demand. And the alternative — the begging — is what she had watched other schools of body mechanics do for fifty years without producing the changes she was producing every day in her advanced classes.
