The dyad: man-energy and gravity-energy
Ida's framing of the body-in-gravity question was unusually formal for a hands-on practitioner. She insisted that the unit of analysis was not the body alone but a ratio — a two-member system in which one term was the gravitational field of the earth and the other was the energy of the living human being. This framing has consequences. It means the work of Structural Integration is not, in her terms, a matter of improving the body in isolation; it is a matter of altering the ratio between two energy fields. In her 1974 lecture for the California Foundation for Healing Arts, recorded in Los Angeles when she was eighty years old, she walked an audience of physicians and researchers through this dyad explicitly, drawing on language she had absorbed from twentieth-century physics.
"Thus, for the word energy to have significance for us here, we must have two members to the system: one, the Newtonian or gravitational energy the other, man consciousness as an energy, for this is the system that you people in this room are interested in and are studying. This is the system whose energy value you hope to enhance, to expand, to increase. Look at it. Energy man, that ratio. Gravitational energy man. This is a system you need to explore if you are looking to increase the energy of the individual man on the earth. This is the energy you need to explore if you are looking to increase the energy, if you are looking to increase negative entropy. In other words, to decrease deterioration. How can you increase the value of this system gravity man? Well, we just oar man gravity, that matter. It's man gravity that basically you are interested in."
Ida lays out the two-term system in the 1974 Healing Arts lecture
The framing is austere: the practitioner cannot change gravity, so the only operational handle is the human side of the ratio. But here Ida's chemistry training does real work. Because the body's connective tissue is a colloidal protein whose state can be altered by the addition of energy, the human term of the ratio is not fixed. It can be made to hold a higher value. The remainder of her teaching on this topic is, in one sense, the working out of this single insight — that the body can be moved up the entropy gradient by the addition of mechanical energy to its fascial structure, and that this elevation can be measured indirectly by the body's increased capacity to use the gravitational field itself as nourishment.
"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."
From the same Healing Arts series, naming the operative mechanism
What we know and what we have found out
Ida was scrupulous about distinguishing what had been demonstrated from what was still speculative. In her opening remarks at the 1974 Healing Arts conference — the same room where Valerie Hunt would later present her electromyographic and aura measurements — Ida set out the propositions she believed had been established. The list is short. It begins with the empirical observation that order can be evoked in the myofascial system by balancing its structures around a vertical line, and proceeds to the logical inference that the gravitational field can either support or disorganize a body depending on whether the body is so balanced. The propositions are connected: structural ordering is the condition under which gravity becomes supportive rather than destructive.
"But that which we do know is exciting enough. What do we know? What have we found out? 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"
Ida itemizes what the work has demonstrated, 1974
Notice the careful phrasing. Ida does not say we believe or we suspect; she says we know. And the knowing is layered. The first proposition is empirical — order can be evoked. The second is logical — given the geometry of the field, vertical alignment is the only configuration in which the field's lines can reinforce rather than destroy the body's own energy fields. This second proposition is where Ida's chemistry training and her structural intuition converge. Here she develops the implication into a more explicit anatomical statement, naming the landmarks that constitute the vertical line and acknowledging that other schools had described the same landmarks without being able to deliver them.
"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."
Ida itemizes the established propositions about order, gravity, and the body
The vertical line itself Ida described in concrete anatomical terms — ankles aligned with knees aligned with hip joints aligned with the bodies of the lumbar vertebrae aligned with the shoulders aligned with the ears. She acknowledged that this same alignment was taught by every accepted school of body mechanics in the twentieth century, with the Harvard postural group at the head of the list. The difference, she insisted, was that no other school taught how to achieve it. Other schools described the goal; only Structural Integration claimed to deliver the means.
"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. We know that the energy fields of the body must be substantially balanced around the vertical line for gravity to act supportedly, thus changing the energy generated by the body. 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. 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. Now this is incredible, and twenty five years ago, no one would have believed this statement. Fifty years ago, they'd have put me in a nice sunny southern room. You've given me pretty good care, maybe. But the body is a plastic medium, and you're going to hear that several times before we get out of here today."
On the vertical line as measuring stick and as plastic achievement
Plasticity: why the body can be reordered at all
The doctrine of plasticity is the bridge between Ida's gravitational claim and her practice. If the body were not plastic — if its myofascial sheaths were not capable of being deformed by pressure and then holding the new form — then knowing the desired vertical would be useless. The whole edifice of Structural Integration depends on a particular chemical fact about collagen, which Ida understood from her Barnard PhD in biological chemistry and her years at the Rockefeller Institute. In her 1974 Healing Arts lecture she gave a compact account of that chemistry: collagen is a three-strand protein braid whose strands are cross-linked by inorganic ions whose proportions shift with age and can be altered by the addition of mechanical energy.
"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."
The collagen chemistry of plasticity, 1974
This is one of the few places in the recorded teaching where Ida descends from doctrine to chemistry. The argument is straightforward: connective tissue is not a passive wrapping but an organ whose state — more gel-like or more sol-like, more elastic or more viscous — is a function of its mineral bonds, and those bonds respond to mechanical input. The practitioner's pressure is, in her formulation, energy in the physics sense, and its effect on collagen is to shift the system toward a state in which the body can hold a new geometric relationship. Everything else in the work — the recipe, the ten-session series, the talk of segments and blocks — follows from this molecular substrate.
"This ratio may be varied by the addition of this energy, and the joint or the connective tissue becomes more resilient, more flexible."
The compact statement of what the added energy does
The random body cannot accept the field
If plasticity is the chemistry of why the work is possible, randomness is its diagnosis of what is wrong with the bodies that come through the door. In her 1976 Boulder advanced class, Ida pressed her students to settle on a single definition of what Structural Integration was for. The students offered various formulations, and Ida pushed each one until she arrived at the formulation she wanted: the random body cannot receive the energy of the earth, and the work consists in moving the body out of randomness so that the field can begin to flow through it rather than against it.
"See, the random body is such that gravity cannot work through it. The field that surrounds the earth can not work through it. It has to work against it. And it is not until you get out of this randomness and you organize that body so that it has a model around a vertical that you begin to get a body which can accept the energy of the gravitational field and utilize it."
From the 1976 Boulder advanced class, on randomness and the field
The framing is sharper than the Healing Arts version. There, Ida had said gravity can support or disorganize the body; here, she says it must work against the random body — there is no neutral option. The energy is constant and immense and indifferent. What changes is the body's relationship to it. Later in the same Boulder session, Ida and her students debated whether the right word for the operative quantity was weight or mass — students proposed both — and Ida settled, with some reservations, on weight. The disagreement is illuminating: she was working without an adequate vocabulary, trying to name a physical quantity that the medical and engineering literature did not yet describe.
"You see it isn't so. You have one physiological unit, example, the digestive system runs from here to here. It runs through all those blocks. And you can't organize the digestive system as a system as I see it in terms of verticality. I'll stay with my weight blocks. I'm willing to argue. Would you accept mass? Would you accept mass? Mass? I don't think I would for the self same reason that I have implied, because those physiological masses run through so many of those blocks. See, all that goes on in the digestive tract doesn't happen in the stomach, namely up in the thorax or near the thorax."
Ida and her 1976 students grope for the right physical vocabulary
When the verticals coincide
Ida's strongest single statement of what happens when the body's vertical aligns with the gravity line comes from the same 1974 Healing Arts lecture in which she defined Structural Integration. The passage is unusual in the corpus because it stitches together the geometric claim (the verticals coincide) with the physiological consequence (the body becomes vitalized) and the experiential consequence (a different state of consciousness). She did not often present the chain in one breath; usually the parts came separately. Here she compresses them.
"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."
The full chain stated in one breath, 1974 Healing Arts
Two features of this passage matter. First, the verb is contributes — Ida is not saying the body draws energy from the earth in some metaphysical sense, but that the geometric alignment permits a constant field to act supportively where it had previously acted destructively. Second, the consequence is not merely physiological but psychological: the man becomes more energized, behavior changes, a different state of consciousness emerges. She would not have called this metaphysical. She would have called it the natural consequence of the body being released from the daily cost of resisting an indifferent field.
"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 ratio man-energy to gravity-energy
Gravity as therapist, gravity as tool
Ida used two formulas to describe what gravity does in the work. The first was that gravity is the therapist. The second was that gravity is the practitioner's tool. The two formulas describe the same situation from different sides. From the client's side, gravity does the actual reorganizing — the practitioner only loosens the fascial bindings that prevent the field from acting supportively. From the practitioner's side, gravity is the instrument the work harnesses, the field whose existing direction the practitioner uses to organize tissue. In her 1973 Big Sur advanced class she pressed her students to recognize that this was the distinctive feature of Structural Integration as a school of healing.
"And tomorrow when I get you all together on the griddle, I'm going to ask you for this answer over and over again in many, many different forms. What does Rolfing contribute to the ideas of the world at the moment that no other schools of? And the answer is that we are using gravity as our tool. So you see, we don't escape to a nice little humble fact sheet. We're just as over proud of ourselves as the medics, but we are using gravity as our field, not chemistry."
From the 1973 Big Sur advanced class, naming the distinctive claim
The 1973 framing came back in Ida's exchanges with senior students in the mid-1970s. In a 1975 Boulder advanced class, she walked a student through how to explain the work to a skeptical questioner — how to assemble three or four sentences that would carry conviction without overpromising. The exchange is instructive because it shows Ida insisting that any defensible account of the work had to lead with gravity as the operative field, with verticality as the achievable geometric condition, and with energetic efficiency as the measurable consequence. Anything less specific, she felt, would not stand up to medical scrutiny.
"Within the field of gravity. And this restructuring of of the body in terms of gravity makes for more efficient use of your body's energy."
Coaching a student on the standard explanation, 1975 Boulder
Note what the formula does and does not contain. It contains the field (gravity), the operation (realignment), the geometry (vertical and horizontal lines), and the consequence (efficient use of energy). It does not contain claims about specific symptoms, specific pathologies, or specific cures. Ida was strict about this. The work was an energy claim, not a medical claim, and she expected her practitioners to be able to make the energy claim without sliding into therapeutic promises she could not defend. In the same passage she went further, naming the practitioner's job in stark terms.
"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."
The practitioner's job stated plainly
Structure, not posture
A persistent confusion in Ida's audiences was between structure and posture. The military and physical-education tradition of the early twentieth century had taught that good posture was achieved by holding the body in a particular configuration through muscular effort — chest out, shoulders back, abdomen in. Ida regarded this entire vocabulary as a category error. Posture, she argued, was what you did with structure. Structure was the underlying relationship of parts. A body whose structure was balanced did not need to maintain its posture; the geometric relationships held themselves, and gravity supported the arrangement. A body whose structure was unbalanced had to use muscular effort to hold a posture against the field, and that effort was, by her account, a sign that the body was losing its fight with gravity.
"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 a Topanga lecture, distinguishing structure from posture
The point is more than terminological. Ida used the distinction to mark the boundary between Structural Integration and every other school of body work she knew. The Alexander people, she said, were on a mind-body trip — they thought they could affect the body through mental suggestion about the head. The various postural schools told you to stand straight, and when you came back the next week still bent, they told you to stand straighter. In Ida's view all of these traditions worked at the wrong level. They worked on posture, which is downstream of structure, instead of on structure, which is the relationship of fascial segments around a gravitational axis.
"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"
On the difference between altering structure and altering posture
Hunt's measurements and the validation problem
Ida's energy claim was, in principle, measurable. In practice the instruments were primitive and the categories contested. The most ambitious validation effort came from Valerie Hunt, a UCLA kinesiologist who in 1974 presented preliminary findings to the Healing Arts conference on bioelectric measurements of clients before and after the ten-session series. Hunt's work used electromyography, electroencephalography, and — controversially — Kirlian aura photography in collaboration with Rosalind Bruyere. The findings were striking: clients who entered with auras half an inch to an inch wide left with auras four to five inches wide. Ida reported the findings with a mix of evident excitement and characteristic caution.
"Rosalind Bried, directly through direct reading of the aura. And amazingly, this age old measurement by Doctor. Brierez confirmed Doctor. Hunt's brand new instrument. Doctor. Hunt could have saved the money, but that's all what all metaphysicians have been telling us for centuries anyway. In terms of measuring light, Doctor. Breyer and Doctor. Hunt have observed its intensity in Kurilian auras Kurilian auras its vibratory rate that is, its color as seemingly created in the body. Thus the aura that Kurilian photographs, the brain waves, as well as increased energy over the various centers that the ancients called chakras were all observed. She 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"
Ida summarizes Valerie Hunt's findings at the 1974 Healing Arts conference
Hunt's own account of the bioelectric findings is more cautious than the aura figures suggest. She reported that after the work the baseline electrical activity rose during rest but dropped sharply during active movement — a pattern she could not initially explain but eventually interpreted as openness to experience rather than tension. She also reported that movement was smoother, larger, more dynamic; that extraneous motion decreased; that erect posture was held with less obvious strain. None of this was as quantitatively clean as Ida's audience would have wished. But the direction of the changes was consistent with the doctrine.
"Well, that could be described many, many technical ways, and that is it has to do with a sensory nervous system. We have to judge through our sensory system how much energy is required to do a particular piece of work and modulate the amount of activity of the muscle to that particular job. Here the modulation was very smooth. There was what we call recruitment of other motor units so that fatigue was not as great. I have a feeling, although I can't prove it, that there was a downward shift in the control of the movement. This is a tremendously important one. There are three major upstream sources. Like having a switch, a three way switch on a light, a source of energy. It can be turned on at various places. Ordinarily, when we turn on that switch, we get exactly the same light or energy source at the other end. But in the instance of the human body, that is not true. If we turn on the muscle or send the stimulus from the spinal cord, we get what's called a very low frequency."
Hunt on the smoother modulation of muscular energy after the work
Julian Silverman, presenting at the same conference, gave a more theoretical account of why thermodynamics was the right framework. His argument was that the two simple laws of thermodynamics — describing the flow and ordering of energy — were exactly the concepts one intuitively reached for when describing what Structural Integration did. The client became more ordered; the client became more alive. Could these intuitions be grounded in a mathematical formulation? Silverman thought they could, and his presentation tried to lay out a model in which the body's myofascial system was an ensemble of energy-generating organs whose vector sum was a measurable body-energy quantity.
"I believe that there is just such a precise objective integration integrating notion that can aptly applied to this problem. It is the concept of energy. In physics, long before the molecular statistical mechanical explanation, the gross properties of matter were described by the laws of thermodynamics. It is one of the most striking testimonies to a parsimony in nature that two simple mathematical formulations were able to describe most of the properties of matter and provide a framework with which to understand these phenomenon on a molecular level. These laws, the first and second of thermodynamics, describe change or flow and ordering of energy respectively. Are these not the very same concepts that one intuitively invokes to describe the process of structural integration? Mainly that the person's structure has become more ordered and that he is more alive, that his energy is more flowing and that he somehow has more of it."
Silverman argues for thermodynamics as the right framework, 1974 Healing Arts
Silverman's mechanical model was even more specific. He treated the body as a network of energy sources connected by springs and viscous dampers — joints powered by muscle, surrounded by connective tissue whose viscosity either dissipated or transmitted energy between segments. The model predicted that reducing fascial viscosity would increase energy flow between joints, but that the flow would be useless or worse if the joints were not phase-locked. The resolution, Silverman argued, was to bring the whole system as near to a resonance condition as possible. This was, in the engineering vocabulary of 1974, what Structural Integration was trying to do.
"Considering first action of a single joint, we see that the viscous elements greatly outweigh the elastic ones, motion will be impeded and energy wastefully dissipated. The problem is compounded when one realizes that all of the individual energy sources are interrelated through myofascial investments. If we examine a simple act such as walking in the light of this model, it is apparent that for maximal efficiency these various energy sources must operate in precise, synchronous, often reciprocal patterns. If the interconnecting networks are overly viscous, then no one joint can be moved without dissipating energy throughout the entire system. If by some process the viscous elements could be changed into more elastic ones, what would the model predict? Clearly, an increased capacity for energy flow between joints is to be expected. Know that this itself will affect an overall change toward more rhythmic efficient energy flow is not true. If the individual elements are still unbalanced with respect to each other, then the increased capacity for energy transfer may be of little use or may even give the appearance of less synchronicity. This is so because all of the modules have their own intrinsic frequencies of oscillation. And if they are in wrong phase relationships with each other, their energies may tend to collide or interfere with one another. What then is the resolution of this problem? The various energy sources must then be modified so as to bring the system as a whole as near to a resonance condition as possible. Returning briefly to the world of structural integration, the first few sessions, mainly the first, are devoted to reworking the superficial fascia. To the practitioner these early sessions changed the resilience of the body tissue to its touch."
Silverman's engineering model of the body as a resonant system
The body as a summation of energies
Underneath the gravitational claim sat a smaller but equally radical claim about what the body is. Ida did not regard the body as a single object with parts. She regarded it as an algebraic sum — the vector resultant of many local energy systems, each contributing positively or negatively to a net body-energy. The liver contributes. The musculature contributes. The connective tissue contributes. What the client experiences as I feel well is the algebraic sum of these contributions, modulated by the cost of holding the whole assembly against gravity.
"And every time you use the word structural integration, You are talking about the relationship between various gross, unitary parts that fit together to make the aggregate that we call the man. Now many of you are aware of the fact that the various parts of the body operate on energy, with energy, by energy, creating their own energy, taking in their own energy. They are individual energy machines. And according to you add these energy machines, appropriately or inappropriately. You get addition or subtraction from the energy machine as a whole. 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."
From the 1973 Big Sur advanced class, on the body as algebraic sum
This framing changed how Ida talked about the work in her later teaching. The block-stacking metaphor that the Healing Arts audiences heard was not just a geometric image; it was an energy claim. Stack the blocks well, and the algebraic sum is maximized. Stack them poorly, and the sum is degraded. The connective tissue system — the collagen system that her advanced students would spend weeks studying — was the organ through which this stacking was operationally accomplished. Everything else in the recipe was a means of working on that organ.
"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. 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. It is the fascial aggregate which is the organ of structure. And the structure basically the word, where we use the word structure, we are referring to relationships in free space. Relationships in space. There's nothing metaphysical metaphysical about it. 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."
On stacking blocks and the organ of structure
Engineering objections and Ida's response
Not everyone in Ida's classes accepted the standard framing. In a 1974 Open Universe class, an engineer student offered a sharp counter-argument: gravity pulls bodies toward the ground, and what holds the body up against that pull is compression through the bone structure, not tensile support through fascia. The body's bones, the student argued, are the only structures capable of taking the compressive load required to keep a standing human off the ground. Soft tissue, in his view, was a tension structure that organized the bones but did not itself bear the standing load. The exchange is one of the few in the corpus where the standard Rolf doctrine of tensile fascial support is directly challenged.
"Yeah, I'd always talks about the body being held up by the soft tissue and talks about tent poles and whatnot and there's certainly, know, certain tent ropes help hold the tent up. But in my view as an engineer, my view of how gravity is pulling on my body is that it's trying to pull it down, trying to pull my head down, my head rests on my shoulders, trying to pull that down, and that eventually there has to be a depressive force to keep me standing up. And the compressive force is this kind of a force and a tensile force is this kind. The only, Probably the only part of my body that can take a compressive force enough to hold me from falling down, gravitational field is my bone structure and I feel that that the gravitational pull on me towards the center of the earth comes down through my bones. You know I feel that it doesn't do it properly unless my unless my tension structure is right. But if my soft tissue, my tension structure that holds my bone structure in the right way, at the very least there's no, I don't need to spend energy to stand up. Biological structures are different from all other structures. I put a bowling ball, set a bowling ball here, it can sit there all night and no work is done in the sense."
An engineer student offers a compression-based counter-model, 1974 Open Universe
Ida's response to this kind of objection was characteristic. She did not deny that bones bore compressive loads; she insisted that the question was wrongly posed. The interesting question was not which tissue takes the load but how much energetic cost the body pays to stand. A randomly organized body pays a high cost — the muscular system continuously works to hold the bones in a non-equilibrium configuration. A structurally organized body pays much less. In her 1974 IPR lecture she made the related point that the twelfth dorsal vertebra — the lumbodorsal junction — was the energy nexus of the body, because the innervation of nearly every visceral system passed through it, and because the structural failure of that segment cascaded into the failure of every energy system it controlled.
"Well, my point right now is trying to think of everything that happens right about this point. Well, the point is everything does happen right and about this you all realize that that twelfth rib, the twelfth dorsal vertebra, is the center for the innovation for everything around except your head. You see, it's the innovation for digestive activity, for eliminative activity, for reproductive activity, for the kidneys, for the adrenals, for the spleen, etc, etc. There is nothing within that body that doesn't have some sort of connection directly, most of them directly, some few of them indirectly, that lumbodorsal junction. And this is what is telling you of its importance, aside from the fact that you can feel it. But for all of these things to work, and particularly for the adrenal gland and the kidneys to get appropriate innervation. That lumbar dorsal junction, that twelfth dorsal vertebra, has to be working. When it breaks down everything breaks down including the energy source that's of the adrenals. So now you have a new way of looking at a body. You have a way of looking at it as an extension of that twelfth dorsal area of that luminal dorsal ridge."
From the August 1974 IPR lecture, on the lumbodorsal junction as energy center
The static balance and the dynamic balance
Ida distinguished two phases in the body's relationship to the field. The first balance achieved by the work was static — the blocks stacked, the verticals aligned, the body able to stand with minimal muscular effort. This was the condition the Harvard postural school had also described. But Ida insisted on a second phase, which only Structural Integration claimed to deliver. As the body incorporated more changes through the recipe, the static balance became a dynamic balance — a balance maintained through movement, in which the body's geometric relationship to the field held up under locomotion and load.
"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."

The dynamic balance is what Ida's senior practitioners learned to test for in the tenth hour. The sign of a successfully completed series was not merely that the blocks stacked at rest, but that the spine could be felt as a continuous wave from the occiput down to the sacrum — that the body had become a transmission medium for the gravitational field, capable of conducting that field through itself without interruption. Anything less was an incomplete dynamic resolution, regardless of how good the static configuration looked. This was the operational test of whether the energy claim had been delivered.
"One way is if you think of the body as a of the body's segments individually as upside down pendulums. And you'll find that in almost all the segments the center of mass is high and it pretty much acts like a like something that's being balanced on a point. Maybe a rather broad point, but even so, the mass is high and it has that sense of balancing of bloom, for instance. The closer you get to the balance point, the less force it takes to keep it there. The closer you get to the balance point, the more potential energy is stored in that segment. And so one way of thinking of that is that gravity potentiates the structure. It provides maximum potential energy. At any moment you can just let go and fall and convert that potential energy into kinetic energy. And if that fall is directed, then this is almost like instant energy, instant available energy. Also, as the segments are aligned along the gravity reference, the moment of inertia of the system is smallest which means that you have, that you can rotate more quickly, can turn. And man, according to Feldenkrais at least in his agitation, man has the smallest moment of inertia of any animal."

Coda: gravity and the changing man
What did Ida think the cumulative consequence of all this energetic reordering was? Her boldest statements treated Structural Integration as a contribution to the local reversal of entropy — a way of running a small region of the universe in the opposite direction from the heat death the second law predicted. The framing came from her exposure to Schrödinger's What is Life? lectures, which she had attended in Zurich in the late 1920s and which she returned to repeatedly in her late teaching. Schrödinger had argued that living systems maintain themselves by importing order from their environment; Ida added that aligned bodies import that order more efficiently, and that practitioners contribute the manual energy that initiates the alignment.
"And, of course, the development of that stress pattern or of those places that are immobilized and hardened, we think is primarily related to the way the body deals with gravity because gravity is the most constant environmental force for the human body. And so it's in response to gravity that the body avoids pain, you might say, or avoids the buildup of stress in an individual point by trying to distribute it. And the fascial system is the way of distributing stress from those points. And so, as doctor Rolf said in the first talk, there's really no cause, one to one cause with the pattern. It's an accumulation of person to the pattern that they presently have. The other part is that we learn inefficient methods of movement. Some people still walk like the toddler."

Ida did not regard the doctrine as closed. In her late teaching she returned often to the point that fascia was the interface between the energy fields of the body and the energy fields of the cosmos — a claim she could not yet prove but believed the next generation of practitioners would establish. This was characteristic of her: the work was an opening rather than a closure. What had been demonstrated by 1976 was sufficient to justify the practice; what remained to be demonstrated was sufficient to justify continued investigation.

The energy-mass-in-gravity doctrine is the one place where Ida's chemistry training, her structural practice, and her cosmological intuitions meet most explicitly. She did not separate them. The collagen that softened under the practitioner's elbow was the same collagen whose molecular bonds shifted with the addition of energy; the body whose blocks restacked was the same body whose algebraic energy-sum increased; the man whose vertical aligned with the gravity line was the same man whose aura widened in Hunt's measurements. Whether one finds all of these connections persuasive or only some of them, what is clear from the transcripts is that Ida regarded them as a single doctrine — and built the ten-session series as the operational embodiment of that doctrine.
