The filter between cells
In the March 1975 Boulder advanced class, Ida had Chuck at the blackboard working through the histology of connective tissue with the senior practitioners. The morning opened with a recitation of the basic cell types — fibroblasts, mast cells, all descending from embryonic mesenchyme — and moved fairly quickly into the question of what fills the space between those cells. The intercellular medium, Chuck said, surrounds virtually every cell in the body. Ida was clear that this was where the consequential chemistry lived. Nutrition, elimination, the passage of metabolic products between cells and capillaries — all of it ran through this medium. To understand the work, the practitioner had to understand that what they were touching with their hands was, at the deepest level, a filter system. The ground substance decided what got through and what did not.
"The brown substance is like the lab of the body. Like a whole chemistry lab. I've got a little thing I want to read about that. The intercellular medium of connective tissue surrounds virtually every cell in the body. This system is the medium through which the osmotic process and nutrition elimination takes place. Metabolic products are transferred between the cells and capillaries, so that surrounds through to every cell in the body. So what's coming through there is influenced by that barrier. I have another general statement on connective tissue."
Chuck reads from his notes on connective tissue, naming the intercellular medium as the lab of the body
The statement carries a quiet structural claim. If the medium surrounds every cell, then anything passed between cells passes through it. Ida had been pressing the senior practitioners for several years on the point that the connective tissue is not merely structural in the architectural sense — it is also where the body's communication and exchange happen. The fluid system in the fascia, the migration of infections along fascial planes, the movement of ions and charges — these all occur in the same matrix that the practitioner is shifting with pressure. To frame the ground substance only as scaffolding misses what it does. It is a chemistry lab, and the practitioner is reaching into it.
"And these cells are the body which are primarily, which are very influential in the body's reaction to systemic disturbances, system wide disturbances. It is in this same matrix that those are parasites that responsible for the body's reactions to the disease. Now, are to all of it. There are various cells that live in this connected tissue matrix and it is these cells that are essential for the body's ability to respond to environmental stress and for the body's ability to respond and to heal itself. So when you are dealing with thatch, you are dealing with, from our point of view, a structural system, a structural organ, literally an organ of structure as I have discussed. But you are also dealing with a very delicate and sensitive environment in which other cells that don't have a direct structural significance live and which can be strongly and powerfully influenced by the manipulation of the fracture. For example, it is common knowledge that often times infections will migrate along the fracture planes. Fluids traverse along the planes. And when Ida talks about the body being basically an electrical something, it is also along fascial planes that these ions need and electrical charges are transmitting. So that you begin to get a feeling that it is literally another system of communication in the body. There is a way of organizing the body. For this we have the nervous system. There is a circulatory system which is another way of providing information chemicals pass through the circulatory system and information gets delayed."

The spiral in the molecule
Once the medium was established as the chemical field, Ida wanted the students to see the shape of the molecule that fills it. Collagen — the protein that makes up the fibrous portion of connective tissue — is a triple helix. Three amino acid chains wound around each other, joined at intervals by inorganic bonds. The spiral was not, for Ida, a metaphor. It was a structural fact she returned to repeatedly. Her 1974 Healing Arts lecture treats it as a defining property of the molecule, and the same point appears in nearly identical form in her 1976 Boulder class. The doctrine is this: structure at every level, from DNA to the dressed body, takes a spiral form, and the spiral is what gives the tissue its peculiar combination of strength and slight extensibility.
"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."
Ida defines the collagen molecule as a braiding of three strands, joined by interchangeable minerals
The Boulder 1975 students pushed the picture deeper. With Chuck at the board, the class examined the molecule's geometry: a spiral going in two directions, which when unwound flattens into a diamond pattern. The diamond — the rhombus of cross-linked fibers visible on dissection — is, at the microscopic scale, the same shape the protein itself takes. The spiral and the diamond are two views of one form. This was the kind of multi-level pattern recognition Ida prized. The arrangement that organized the molecule was the same arrangement that organized the bundles of fibers, and the same arrangement, on the gross level, that the practitioner could see in a dissection.
"Now this arrangement can be brought up, and we're getting ahead of ourselves now, all the way to the gross level. So if you do a dissection, you can go, oh, I see it. So I think this is an arrangement that starts right down at the microscopic level. If you look at the collagen molecule, it's a triple helix. There's those diamonds again if you lay it out. And I think it's that shape because it allows that extensibility, slight extensibility. I think it's that shape because of what's in the collagen molecule. You got a spiral going in one in two directions. You open it up, and you have diamonds. Just wrap that. Now let's just keep going on with this diamond trick for a few minutes."
Chuck explains how the collagen molecule's triple helix produces the diamond pattern visible at higher magnifications
Ida liked to remind her practitioners that the spiral was a structural form running through far more than the human body. In a 1974 Healing Arts lecture, Dorothy Nolte — one of her senior colleagues — laid out an extended analogy: graphite and diamond are both carbon, but graphite's molecules lie flat while the diamond's molecules are arranged in a spiral, and that single difference of geometry accounts for the difference between a soft, dull material and a hard, brilliant one. The spiral is what makes the diamond a diamond. The same logic applied to DNA — a spiral structure carrying both reproduction and the program for growth. Ida heard in this not metaphor but pattern.
"To give you some of the examples of what this has meant is to relate to you that graphite and diamonds are of the same substance they are of carbon. And yet they differ immeasurably. Graphite is one in which the carbon molecules are laid flat. They have a tendency to slip one upon the other. It makes it soft material. It also makes it of a different color and it makes it a very ordinary type material. In contrast to that, the molecular structure rings of the diamond, which is also carbon, are in a spiral effect. They interlock. They make the substance extremely hard, make it shine and glimmer, and it is precious. Sulfur drugs that we are all quite familiar with work, and they work basically because they simulate the arrangement of the substances of the human body the arrangement of the atoms. And as a result, bacteria misplaces the atoms of the sulfa drug for that of the human body and it is devoured."
Nolte offers the graphite-and-diamond analogy that Ida used to teach why the spiral matters
Nolte did not stop at graphite and diamond. She extended the same structural argument upward, to the genetic mechanism of life itself. The spiral of DNA was, for her and for Ida, the most dramatic available example of how shape carries function. It is the structure, not the bare chemistry, that carries the program of growth. This was the framing Ida wanted her practitioners holding when they thought about collagen and about the ground substance. Identify the shape, and you have identified what the material does. The spiral is the operative variable across multiple scales of biological organization, and the body's connective tissue is one more place where it shows up.
"I think the most dramatic focus that we have on this type of approach comes from understanding the molecular structure of genetic mechanism of life And the spiral structure of DNA I'm talking frequently about spirals. On Wednesday I'll talk more about spirals, about the shape and the arrangement of materials. But the spiral structure of the DNA carries the ability to reproduce itself. It is not the basic elements it is the structure of it. And it carries also the program for growth and for development of the unfolding human organism or living tissue. Well, that's all I'm going to say about the century and about an approach to research, except to say that structure is not a thing in space. It cannot really be defined specifically as a thing in space."
Nolte names DNA's spiral structure as the carrier of the program of life
The protein spiral in the ground substance
Having established the collagen molecule's spiral form, Chuck and Ida turned to the ground substance itself — the gel between cells in which the collagen fibers are embedded. Here, too, the spiral appeared. Within the ground substance, large protein molecules wrap themselves in a spiral arrangement; the spiral creates a filter, holding back molecules too large to pass while letting smaller molecules through. This is the central claim of the topic and one of the most chemically specific passages in the entire advanced-class archive. The ground substance is not a homogeneous jelly. It is structured. And its structure is, once again, spiral.
"Go back to the ground substance of the intercellular medium. That's actually like can be called a filtering system. In other words, it's big molecules and large molecules. The big molecules can't get through, only certain molecules with certain sizes. Within the ground substance, there's that those protein molecules wrap themselves in spiral. There's a two dimensional of it. Three-dimensional would be like this. So the big molecules are held out by this spiral arrangement here."
Chuck names the ground substance as a filtering system and describes the protein spiral that does the filtering
The passage repays close attention. The spiral in the ground substance does work — it filters. It is not decorative. The geometry determines what molecules can move and where. And, Chuck continued, the arrangement is not uniform across the body. Where mechanical stress is greater — in ligaments, in tendons, in regions of high load — the protein arrangement changes. Where stress is lower, the matrix is loose, mesh-like, with fibers crisscrossing in many directions. Where stress concentrates, the fibers align, the protein arrangement densifies, the filter becomes tighter. The same collagen, the same protein, organized into structurally responsive variants.
" Now you have to understand that this is where it's all come together, okay? And so there is a there's actually tissue that's between this and this, okay? That looks like something between this and between this. So that here, most of your fibers are running one way, they're kind of running like that, not so cross linked, but almost cross"
Chuck describes how the protein spiral's arrangement varies with mechanical stress across the body
Chuck wanted the class to see this responsiveness in concrete histological terms. The same collagen fibers, he showed them with diagrams, formed three different tissue types depending on how they were arranged: loose connective tissue, where the fibers ran in many directions in a flexible meshwork; ligament, where they were partially aligned and somewhat overlapped; tendon, where they ran in a tight parallel rope. The same protein, the same molecule, three different macroscopic outcomes. Density was the variable the practitioner felt on the hand. Where the matrix was looser, the tissue moved freely. Where it had densified — by injury, by chronic load, by age — it resisted.
"This is an aggregation of collagen fiber. It forms a collagen bundle. That gives you sort of an idea. And there's two little ropes coming out. Sure. I'm gonna do all that stuff right now. This is a diagram showing there's three types of range of collagen fibers, denser, regular connective tissue, and then a ligament, and then a tendon. And you can see how this the same stuff, basically, just becomes denser. That's what you actually feel on your hands is the denseness of it. So this is the loose connective tissue. Oh, you erased it. And this is a ligamentous. This is a ten minute. And it's all basically these collagen fibrils. And so And they have disc they're they're interwoven here. Here, they're more interwoven and overlapped. And here, they're together like a rope."
Chuck walks the class through the three densities of collagen tissue and what they feel like under the hands
Collagen as colloid
The next move in Ida's doctrine was chemical. Collagen, like all large protein molecules, is a colloid. Colloids share a distinctive physical property: by the addition of energy, they shift state — from a more solid gel toward a more fluid sol, and back again. Ida illustrated this constantly with the kitchen analogy of gelatin. The example was deliberate. Jello is collagen. The pan of gelatin in the refrigerator becoming the bowl of liquid on the stove is, in chemical fact, a model of what happens in the connective tissue under the practitioner's hands. Subtract energy, get a gel; add energy, get a sol. The body, in its dense and resistant places, is in a too-much-gel state. The work adds the energy that returns it toward sol.
"Like all body proteins, collagen is a colloid. It has a very high molecular weight. It is very complex. And it consists basically of three chains, protein chains, interlinked by mineral and hydrogen atoms. It is characteristic of all colloids that their physical state alters drastically by the addition of energy. You have experience of that right in the kitchen. You heat the colloidal aqueous suspension of jello, and it becomes clear what you think of as a solution, and it takes a chemist to see that it is a naceous sort of a thing that you realize, if you're a chemist, that it's not a true solution. It's a suspension. But at any rate, it flows, and it flows easily, And the chemist would say, it is in a sol state. And then you take it off the fire, and you put it into the refrigerator, and lo and behold, in very few minutes, you begin to get solids in the bottom. You begin to get a solid bottom, and presently it is solid throughout. And the chemist says, it is now in the gel state. And in his mind, he's going over the fact that you take energy away from the sol, and you get a gel. You add energy to the gel, and you get a sol. Now, listen to what that is saying to you. It is saying that if somebody can add energy to those colloids which have become much too much of a soul. Oh, how I hate to get up in the morning, my back bothers me, I can't straighten up, I go around so slowly, I must be getting old. Well, the next time you want to try that song, try it to a different tune."
Ida lays out the colloid chemistry that makes the work possible
The pressure of the practitioner's fingers, elbow, or knuckle is the energy in question. Ida was careful to specify what she meant. Not reflex stimulation. Not nervous-system signaling. The energy is mechanical pressure applied at the right point in the right direction, and what it does is shift the physical state of a colloid. The analogy to heating jello is exact in the relevant sense: the addition of energy to a colloid changes its state without changing its composition. The molecules are the same. The relationships between them are different.
"Collagen is a colloid and as are all large molecules of protein molecules of protein. Colloids have certain qualities in common. An outstanding one is that by the addition of energy, they become more fluid, more resilient. You remember that half set pan of gelatin in water? And water, it's gelled. You set it back on the stove, you turn up the light, and lo and behold, it liquefies. You take it off the stove, you set it in the fridge, and lo and behold, it solidifies. These this is a generalized quality of colloids and it is a generalized quality of the connected connective tissue of the body. Add energy to it and it becomes more fluid, more sol. Subtract energy and it becomes more dense, more solid, a gel. And as I said before, what do we mean by energy? In the case of the jello, we're talking about heat. In the case of the body, we may be talking about heat. Remember how different your flesh feels to your fingers in the very hot weather? There are people where you put your hand on their flesh in very hot ninety, hundred degree weather and it feels as though you're going right through them. But in terms of roughing here, we are talking about pressure. Pressure at the right points, in the right directions at the hands of the roper. Some of you are saying, oh yes, you mean reflex points. No, I'm not talking about reflex points because in my opinion, reflex points have to do with a nervous phenomenon, phenomenon of the nervous system in some fashion. I'm talking about energy being added by pressure to the fascia of the body. By the way, are there any people in this room that don't know what I'm talking about when I'm talking about fascia? Hands up? One, two okay. I'll give a quick go over."
Ida states the doctrine plainly: pressure is the energy added to the colloid
The bonds between the strands
Ida liked to anchor the sol-gel mechanism in a specific chemical claim about what holds the triple helix together. The three protein strands of collagen are united by mineral atoms — hydrogen, sodium, calcium — at intervals along their length. The composition of these bonds varies, she taught, with age and with the body's energy state. In younger, more fluid tissue, the bonds tend to be the lighter atoms: hydrogen, sodium. In older, stiffer tissue, calcium predominates. Stronger bonds, denser tissue, less mobility. By adding energy through pressure, she said, the practitioner could shift the composition of these bonds, replacing heavier cross-links with lighter ones — and so reverse some of what looked like the inevitable progress of aging.
"Now, is the property of certain proteins, but not all proteins. But it is the property of collagen and because you are mostly a collagen machine it concerns you very intimately. Now that collagen actually changes its chemistry because collagen is a protein which is a weaving of three strands amino acids and other substances. And those strands are united by mineral atoms. According with the energy which is in that body, those mineral substances will differ. In the case of a young person, those unions may be hydrogen, may be sodium. As a person gets older, these elements change and the mineral unions become calcium. You all know what happens when there gets to be too much calcium."
Ida names the mineral bonds and explains why the bonds change with age
Chuck in the 1975 Boulder class supplied a more recent version of the same argument with an additional mechanism. There are two theories of aging in the connective-tissue literature, he told the class. One involves the cross-links — replacing heavier metal cross-links with lighter hydrogen ones. The other involves hydration: when the tissue holds water, the water molecules wrap around the collagen molecules in a structured arrangement, holding the spiral proteins apart. When water leaves, the collagen molecules collapse toward each other under their own electrical forces, and the bonds between them strengthen. The practitioner's pressure, he speculated, mechanically spreads the area, allows circulation through, and rehydrates the matrix. The tissue fluffs out. Both mechanisms are versions of the colloid story: water and energy redistributing across the spiral-protein matrix.
"The two theories on the main theory on aging is that these in beneath in between these molecules, there's numerous cross links, and there's hydrogen ones and heavier metal cross links. Possibly with Rolf, we replace the heavier ones with hydrogen ones, which are lighter and not so strong. The stronger bonds make the tissue more, you know, like stiff knees. Rigid. Rigid. Right. And elastic. The thing that most of the articles don't bring out, there's another way to cause that with not messing with the cross links. In fact, there's a couple ways. When the tissue is hydrated and has plenty of water, the water forms around the collagen molecule in three, four, five, or a pentagon arrangement. In other words, it spans the collagen molecules apart, pulls them apart from each other. When water is not in the tissue, they get close together. The reason they get close together is electrical forces between each molecule. And as soon as they get at a certain point, those electrical forces get real strong on the level of those covalent bonds, real strong bonds. So I think when we're often, the circulation comes we get in there and mechanically say, spread that area so the circulation can come through. Water and whatever else comes in there, and probably hydrates those molecules and the tissue fluffs out."
Chuck offers two mechanisms — cross-link replacement and rehydration — for how the work changes the matrix
The diamond pattern at every scale
One of Ida's most distinctive teaching habits was to insist that what was true at one scale was visible at every other. The diamond pattern formed by the unwound spiral of the collagen molecule reappeared at the level of the fiber bundles, and reappeared again at the macroscopic level of fascial planes. Chuck pressed this point with the class. Take a microscopic view of irregular connective tissue, he said, and the cross-hatch pattern looks random. Back off and look at a broader view of the same tissue, and an organization appears — a crisscross arrangement of fibers, the same diamond pattern showing up at the larger scale. The geometry of the protein spiral propagates upward through the tissue.
"That irregular tissue, if you look at that picture right there, looks really random. That's a microscopic shot. In other words, a tunnel vision of it. If you back off and take a broader view of that type of tissue, it takes on a organization that's discernible. And that organization What's I'm again? Intercellular medium, I also call brown substance. K. Now this is really important, I believe. If you back off from that irregular range tissue, the first picture, take a broader view of it, you start seeing a fiber arrangement that looks like this in two dimensions now. In other words, a crisscross type of arrangement. Now why would the body have that? Now if you take just take one of these little crisscrosses right here, it's a diamond shape. Okay. Now since this tissue has to have some plasticity, it's not solid like cement. It moves like when you move your leg, the fascial planes change shape. Okay? So what type of fiber arrangement does there have to be for that to happen?"
Chuck shows how the diamond pattern of the protein spiral reappears at the broader tissue scale
And then, in the 1976 advanced class, Ida and the senior practitioners pushed the diamond upward one more step — to the body as a whole. The same spiral form that appears in DNA, in the collagen molecule, in the matrix of the ground substance, appears in the gross spiral patterns of the dressed body. The pelvis spirals one direction; the shoulder girdle spirals the opposite. The pattern of the body's overall organization is, like the protein, a coiling around a vertical axis. Ida did not press this analogy as proof. She offered it as a high-order abstraction worth meditating on — the kind of pattern recognition that linked her chemistry to her structural work.
"Picture. Everybody gather around. One other high order of abstraction is that you can have an overall spiral of You're whole talking probably that some basic structures like the DNA molecule and also probably the way the collagen is put together on the molecular level is an abeligible shape and then we start looking at the body as a whole. I'm wondering, I don't have any sense other than the coincidence of those structures of what we're talking about here in class in terms of seeing bodies as a human constructor Helix, anything having a spiral form. Spiral, wave. No, no, we do better do that. Spiral, winding, coiling, circling around a center pole, gradually receding from it like a screw or a watch screw or the interview. That's not the matter. It's a spiral winding, coiling, And she said, Noah, Let's say the whole body is like a cylinder. And then you can also just break your legs and arms down like a cylinder.
From a 1976 class discussion proposing the spiral as a pattern visible from DNA to gross body organization
The fibers respond to load
If the protein spiral and the diamond meshwork are responsive to mechanical stress, then the body's history of load is written into its connective tissue. This was a doctrinal point Ida pressed hard. The fibers lay themselves down to resist what they have had to resist. A connective tissue grafted from one place in the body to another rearranges its fibers to match the new mechanical environment. Carry a heavy bag on one shoulder for years and the fibers in that shoulder will not stay in their loose meshwork — they will align, densify, move toward the ligamentous and ultimately the tendinous pattern, because plain mechanical tension is the stimulus to lay collagen fibers down along the line of pull.
"The unique The collagenous organization right new addition. Influenced the plasticity and the mobility of mucus and structure. To you? Here's something really interesting. Yes, The fibers tend to be laid down to resist. So plain old mechanical energy is probably the stimulus to lay down collagen fibers. So if you walk around carrying a golf bag on this shoulder that's short, the fibers may start, instead of being a loose meshwork, something that's flexible, the fibers, instead of being, say, like that, something loose, they start laying down more like tendon just because tension, plain mechanical tension, is a stimulus to lay those fibers down. Said that. Where where is it said? Oh, that's everywhere. It's lots of places. But, you know, what I'm trying to talk about is, like, what you really need is is a very definite reference to it."
Chuck describes how mechanical tension reorganizes the collagen matrix
Ida traced this responsiveness back to embryology. In the mesoderm, the cells that become connective tissue stop differentiating earlier than the cells that become muscle or bone. They remain at a less specialized stage. They retain, she said, greater freedom — greater potential energy. This is why the matrix remains responsive throughout life to environmental demand. The collagen-producing cells generate fibers in patterns that respond to the mechanical environment because they never finished committing to one specialized form. The same primitivity that made them adaptable to whatever shape the embryo would take is what makes them, in the adult, still responsive to the practitioner's pressure.
"They are all related and they differentiate depending upon the source of energy that flow through them, the kind of environmental influences they coming through. Now as these cells become more and more specialized and as the embryo develops, there is one cell which stops at a certain level of differentiation and just becomes faster. Fracture is the connective And this is significant that fascia, the connective tissue cells are the least differentiated and I am not speaking here about the extruded collagen fibers, I am speaking about these basic cells that generate the fibers. Because you have to remember that fascia is a matrix of connective tissue fibers called collagenous fibers along protein strands in which live the cells of the connective tissue. And it is these cells that generate fascia. So the And fascia is formed from the least differentiated cell. In that sense it is the most primitive and also the most labile because it hasn't gone as far down the road for specialization. It stopped before it has had to make all these decisions about is it going to be bone, is it going to be muscle, is it going to be And it stays right there. And hence it has greater ability, has greater freedom, freedom, it has, in a way to look at it, has greater potential energy. So we have a cell which is capable of generating this fibrous matrix."
From the 1973 Big Sur class, an account of why connective-tissue cells stay labile
Stuckness, fluid, melting
What happens in the matrix when the work succeeds? Practitioners spoke of warmth, melting, places that had been fixed becoming free. The phenomenological language varied; the underlying account Ida and her circle gave was consistent. Tissue that gets stuck between fascial planes is stuck because the fluid medium has become densified — too gel — and possibly because additional protein has been laid down in response to old injury or chronic load. When pressure is applied at the right place, the colloid shifts; the densified matrix returns toward sol; the planes can move on each other again; fluid that had been pooled in the tissue is released and reabsorbed. The melting is the colloid changing state.
"You know, all I know is what I experienced and that is that oftentimes there's a warming, like a melting feeling that the place that was stuck or the place that wasn't moving, all of a sudden it gets warm and starts moving. That's my point. You're moving something. They get stuck partially by hardening or there's a fluid substance that seems like that has been hardened and isn't reabsorbed in the flesh. Time of injury, time of sickness. And it seems like whatever it is that is that stuckness between the layers of the fascia is what's reabsorbed at the time when our pressure is or energy is is placed on the body. And I don't know what further to say except that that's the way I feel what's going on. 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."
A practitioner describes the warming and melting that occurs when the matrix shifts
Ida was careful never to claim the chemistry was settled. The colloid model was, in her teaching, the best available account, but she did not present it as proven mechanism. What she insisted on was the structural pattern: pressure adds energy; energy shifts the colloid; the protein spiral and the fluid medium together respond. The clinical evidence — bodies that change, fluid that releases, tissue that softens, function that returns — supported the model without depending on every molecular detail being right. The doctrine was offered as the most parsimonious account of what the practitioner could observe with the hands.
"You can look at the fascial system in a similar way. There is a fluid system in the fascia and you see this, we had a woman yesterday, we had, where you have fluid collected in the legs. And you can literally see that once those fascial planes unstuck from each other, that fluid starts to leave and that the mechanisms that are there for the removal of that fluid can start to work. It is through the fact that that happens. It is that extrinsic fuel to which it is outside the central nervous system."

Why this chemistry matters for the work
Why did Ida spend so much of her advanced-class time on the chemistry of the ground substance and the geometry of the protein spiral? Not because she wanted her practitioners to become biochemists. Because she wanted them to understand that the work was not metaphysics, not energy mysticism, not faith. It was the application of pressure to a colloidal medium with known properties, organized by a protein with a specific geometry that responded to mechanical input in describable ways. The chemistry was the rebuttal to anyone — particularly medical authority — who dismissed the work as massage or as suggestion. What the practitioner was doing was understandable in the terms of physical chemistry circa 1930, the chemistry Ida herself had trained in at the Rockefeller Institute.
"And the other factor is the quality, the chemical quality, the physical quality of connective tissue, of fascia, of that myofascial body which differentiates from the mesenteric. Now what do I mean by that? I mean that this protein collagen, which is the basis of all structure, has peculiar qualities, with your elbows. Don't let me catch you doing it with your knees. You can add energy to that collagen and as you add energy to it you can change the chemical structure. Just as you take some gelatin and water and it's semi solid, you put it on the stove and you add energy to it and it becomes a fluid. Same color, same gelatin, same water, little more heat. In other words, a little more energy, and it becomes fluid. You take it and you quickly set it in the freezer, and lo and behold, in no time flat, it's solid or semi solid. Now these are the this is the property of certain proteins, but not all proteins. But it is the property of collagen. And because you are mostly a collagen machine, it concerns you very intimately. Now that collagen actually changes its chemistry because collagen is a protein which is a weaving of three strands amino acids. And those strands are united by mineral atoms."
Ida ties the colloid chemistry to the practitioner's possibilities
The chemistry also explained the limits. A colloid responds to energy within bounds. Beyond a certain elasticity, the deformation becomes permanent. Beyond a certain age, beyond a certain depth of mineralization, the bonds may not exchange easily. Ida acknowledged this constantly. The work was possible because of plasticity; it failed where plasticity had been exceeded. The ground substance, the protein spiral, the colloidal medium: these were responsive within a range, and the practitioner's skill lay in knowing where in that range a given body was. The chemistry was both the warrant for the work and the description of its boundaries.
"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."
Ida names the connective tissue, the collagen system, as the organ of structure
Coda: the spiral all the way down
Ida's teaching on the ground substance and the protein spiral was, in the end, an argument about levels. The same form — the spiral, the diamond, the structured arrangement of large molecules in space — appears in the DNA that carries the program of growth, in the collagen molecule that builds the body's structural organ, in the protein matrix of the ground substance that filters between cells, in the fiber bundles that the practitioner palpates, and in the gross spiral arrangement of the dressed body in gravity. The work, when it succeeds, is one geometry corresponding to another: pressure applied along the lines of the body's spiral organization, energy added to a colloidal medium that responds along the lines its molecular spiral allows. Ida did not claim to have proven the chain. She claimed it was the most coherent account of what her practitioners' hands were doing.
"This is the bag with all this stuff in it, just like the body. What are you gonna do to organize that stuff? How are you gonna do it? Well, the fascial planes are the organizational material for the body. It's what I think. K. And if you look at it from an evolution standpoint, there's some massive protoplasm there. As that protoplasm gets more organized, in other words, higher structures come to be like a nervous system, the nervous system gets more organized. In other words, instead of a bunch of cells just floating around into this large massive protoplasm, the connective tissue organizes that into a system. Okay?"
Chuck closes the discussion by naming connective tissue as the organizing principle of the body's contents
The practical instruction Ida drew from all this was deceptively simple. Find where the matrix has densified. Apply pressure along the lines that will let the colloid return toward sol. Trust that the protein spiral, having responded to the body's mechanical history on the way in, will respond again to the practitioner's mechanical input on the way out. The chemistry was the warrant; the geometry was the map; the felt event under the hands — warming, melting, the planes coming free of each other — was the confirmation. The ground substance and the protein spiral were not abstractions. They were the thing being touched.
