The shopping bag and what is inside it
Jim Asher's shopping-bag image, developed across multiple sessions of the 1975 Boulder advanced class, is the most durable teaching device the circle produced for distinguishing the two fascial systems. The superficial fascia is the flexible bag; the deep fascia is the system of partitions and wrappings inside that bag which sort and organize what the bag contains. Asher is anatomically careful — he wants the practitioners to feel the difference on the back of their own hands, where the loose slippery layer over the deep fascia is palpable, versus the palm, where it is not. Ida sits with this teaching and presses on the terminology, occasionally screaming inwardly when students conflate the layers. The exchange below, from a Boulder session in the summer of 1975, opens the doctrine by naming what superficial fascia actually is anatomically — not a vague "surface tissue" but a specific bag with a specific location.
"Anatomically, the superficial fascia, the flexible sack. Just like a a bag. A shopping bag. Oh, I'm just gonna do that one here. Fable old party. It's a flexible bag containing everything in a very general relationship. Like, here's a bag, and all the body parts are in there. Very general relationship. Flexible bag."
Asher in the 1975 Boulder advanced class, with Ida correcting his terminology in real time:
The bag has two layers — and this is where the anatomy starts to do real teaching work, because the inner membrane is what permits the bag to slide over the deep fascia at all. Without that thin elastic membrane, the practitioner's hand would never feel the difference between working a superficial layer and working a deep one. Asher's next move in the same session is to name the histology of those two layers — the adipose outer layer that contributes to body contour, and the elastic inner membrane that makes the sliding possible. This is the most concrete piece of anatomical teaching in the archive about what the superficial fascia actually is.
"The superficial fascia has two layers. There's an outer layer which is like adipose tissue. It's thick, very loose, and there's an inner layer that's like a membrane. Those two are connected pretty strongly. Okay, the outer layer's adipose tissue contributes to body contour, provides insulation and storage of nutrients. The inner layers are thin membrane, large amount of elastic tissue. So the superficial fascia can slide over the deep fascia."
Asher continues, naming the two-layer structure that makes the bag able to slide:
Where the bag ends and the architecture begins
Inside the bag is a different order of tissue altogether. The deep fascia is not loose, not adipose, not flexible in the same way; it is the outer investing layer that holds the muscles in their proper places and the intermuscular septa that subdivide those compartments. In the 1975 Boulder transcripts, the practitioners keep wanting to collapse the distinction — to say that superficial fascia is "just the skin" or that the investing fascia and the deep layer of superficial fascia are the same thing. Asher pushes back. The deep fascia is strong, not skin-like; it is what holds the compartments together; it interconnects with the intermuscular septa to form the architecture. The passage below is from the same Boulder week, with Ida sitting in and Asher answering a student's question about the relationship between the deepest layer of the superficial system and the intermuscular septum.
"The outer investing layer. Here is the outer investing layer of the deep fascia, and out here is the superficial fascia skin. I'm just not gonna draw that anymore ever. So anytime it's here. Oh, that stuff is. There's the outer layer of the invested fascia."
Asher, drawing on the board during a 1975 Boulder session, naming what lies inside the bag:
The architectural function gets more specific when Asher walks the practitioners through the leg. The fascia lata is not a single sheet but a system of tubes and compartments, blending with the periosteum of the bone (not attaching to it — a distinction Asher insists on), running from crest to ankle, dividing the muscles into functional groups. This is what the second hour is doing when it works the lower leg: it is reorganizing not the bag but the compartments inside it, the architectural subdivisions that determine how the leg moves as separated functional units rather than as one undifferentiated mass.
"It's an outer investing layer. It's okay. Let's go take another look at the superficial fascia for a minute. Just like these surfers wear these wetsuits, that's the superficial fascia. Just below that, there's another wetsuit. So another wetsuit. In other words, wrapping the whole body from head to toe. K. Within that, there's numerous planes. There's, like, the large what I call the large extrinsic planes. That's what we were looking yesterday with Gallaudet. On the leg, this is here's the superficial fascia out here, sweetheart. I'm not gonna mention the superficial fascia anymore. There it is out there. Here's the deep fascia. These lie, like, right next to each other. Let's draw a plane like that. There's numerous planes going through here. This is, all large extrinsic stuff. We'll talk about that in the skeleton in a few minutes. K."
Asher, opening the second day of the Boulder fascia sequence, expanding the bag-and-planes image into the deep architecture:
Why the distinction matters for the first hour
The doctrinal payoff of the superficial/deep distinction is that it lets Ida explain what the first hour actually does. For years she had been telling students that the first hour worked the superficial fascia; for years many students did not believe her, or did not understand what that meant. The teaching becomes clearer when she pairs it with the architectural picture: in the first hour you are stretching and reorganizing the bag, and by virtue of changing the bag you begin to get change in what the bag contains. The bag is not trivial — it is the first level of where the joints are tied down, and you cannot go deeper until you have addressed it.
"Now when you come right down to it, we've been doing that in the second hour. When you go and you get to those extensor muscles in the back, you are certainly at a deeper level than you were when you were working with that superficial fascia. In the early stages of the game, nobody believes that you're really working with that superficial fascia in the first hour. But actually, as you go further along and get more familiar with it, you begin to realize that you are working with that superficial fascia and that you are stretching that superficial fashion. And it is by virtue of the change that you put into the superficial fashion that you begin to get change in underlying structures."
Ida in a public-tape teaching session, explaining what students take years to accept — that the first hour really is superficial-fascia work:
The reverse follows: you cannot dig deep until the surface has loosened. This is the principle Ida and her circle press on repeatedly when teaching new practitioners. The 1976 advanced class makes this point in anatomical detail, with Ida and her colleagues using cadaver dissection slides to show that the work proceeds in layers because the body itself is layered, and because the deeper structures cannot be reached until the looser stuff above them has been freed.
"Obviously then rhomboids underneath are not much. I agree that the sheets, I think I can do it in less than ten minutes, at least as far as I can go right now, is that the sheets that are happening, the straps, the thicknesses, the whatever, are not only going around the body but are going deep into the body at all different ways. So that in the process of working on superficial fascia you're doing some very deep work because it's, or it may be the lack of, a better tone or something like that. We're starting to get a looser In the process of the first hour, number one I said we're getting to the joints and we're still dealing with a superficial fashion. So that we are starting working at the joints and the fact that the joints back here as well. But that we are working in terms of levels of where those joints or how those joints are tied down and this would be the first area that they're tied down is on the surface. And that we cannot go freeing them by digging deep, say into the axillary region or deep into the hip joint until we've got the looser stuff. It's a kind of tone or a bed in which these kinds of movements can happen."
From the 1976 advanced class, working through dissection slides of the shoulder and back:
The cadaver slides and the layer-by-layer descent
In the 1976 advanced class, Asher had prepared a sequence of cadaver dissection slides — taken from a forty-three-year-old male, somewhere in the back near the latissimus dorsi — that show the layers being peeled back one at a time. The pedagogical move is direct: rather than argue from analogy or from drawing, the practitioners see the actual tissue, millimeter by millimeter, as it is removed. The slides reveal that what the textbooks call "superficial fascia" is itself stratified, and that the transition into the deep fascia is gradual, not abrupt. The terminology issue that Ida and Asher had been pressing for years becomes visible: the layers do not fall into the clean categories the anatomy books name.
"Well I thought maybe that was shown on the slides of the As I said, was very sleepy at 07:00 this morning and at least isn't upside down even if it is backwards. But this was a, actually this was Jim Asher's creation of getting the concept of the layers of fascia down starting with the external skin. This was a 43 year old male of the cadaver. This was the external skin I think were taken somewhere in the back, somewhere up in here, in the latissimus dorsi region. So that we have then the skin here then immediately what we did was to peel just the skin back. This is leaving probably partly dermis. This is the same thing here, these two. And so that this is the kind of tissue which you see is, it has some fat in it but it's a very tough tissue in terms of texture. It is not a giving easy tissue to work with. Then we sort of artificially went down another layer so this is what we saw still in just the layer below that. Now these are a matter of probably a millimeter that we're taking. It's a very thin area. Then we took this off so we go down to this region. Now this is all what we call superficial fascia according to the classical definition. And then we're down to the fascia that is immediately over the muscle itself which we call the deep fascia or I started to call the deep, the superficial deep fascia which is something we have to do about terms. So it's really in a sense a cross section of the skin, the kinds of things that we're working through. Now these few slides are mainly to give you an idea of different kinds of fascia and that we have layers of fascia or fascia sheaths which I feel are due to the concept is the tough sheaths are due to improper use of the body."
Ida narrating Asher's 1976 cadaver dissection slides for the advanced class:
The same 1976 session reveals something else: the layers under dissection do not show the tidy planes the textbooks promise. Fibers run in multiple directions; fat is interleaved with connective tissue; the difference between one layer and the next is sometimes a matter of texture and translucency rather than a clear anatomical break. The classical superficial-versus-deep distinction is real but messy. This empirical messiness is what eventually pushes Ida toward a different vocabulary altogether.
Ida's revision: from fascia to connective tissue
By 1976 Ida is openly revising her preferred terminology. The word "fascia" — which she had used for decades, which had become identified with her teaching — was, she felt, leading the practitioners into trouble. Fascia tended to mean "the wrapping around muscle," and that was too narrow. Every organ has its fascia. Every gland has its fascia. The myofascial unit is one piece of a much larger system that includes the connective tissue around every organ, every blood vessel, every gland. To call it all fascia obscures the scope of what the practitioner is affecting. Her preference now — and she is honest that she does not always remember to do it — is to call it connective tissue.
"My preference now and I don't always do it because I've got to change my head on this is I prefer to call it connective tissue. I think we're in a lot less trouble if we do it."
Ida in the 1976 advanced class, announcing a shift in her preferred terminology:
The revision is significant. Ida is sixty years into her career, eighty years old, and she is naming a vocabulary problem that she helped create. The shift to "connective tissue" is not a repudiation — it is a refinement. The work is still myofascial in its mechanism, but the practitioner's mental picture must extend to the glandular fascia, the visceral fascia, the perivascular fascia, all of which are being affected when the practitioner organizes the body. The same 1976 transcript makes the broader point: the contour of the body is determined by the connective tissue, not by the muscle, and the practitioner who thinks only in muscular terms has misunderstood what is being changed.
"And you can see the pull here of the strap which is pulling that buttocks, really think I got some pictures of Why at this point to talk about useful or effective tissue versus mild fascial tissue, etcetera, etcetera?"
Ida, in the same 1976 dissection session, naming the operative claim about contour:
The terminological war: skin, septa, and what the layers really are
The vocabulary problem is not only Ida's. The 1975 Boulder transcripts capture a running argument among the practitioners about what to call the superficial fascia, whether it is "the skin," whether the layers can be cleanly separated from each other, and whether the various sheaths are connected or are simply one continuous tissue. Asher takes the harder line — they are one thing, embryologically and structurally — while the students keep wanting to separate them into named units. The exchange below shows the back-and-forth in the room.
"And that is sort of separated structurally, functionally from the deep layer of the superficial fascia? Yeah. Yeah. Okay. Why don't we just say the superficial fascia is the skin? Mm-mm. It's not the skin. That's no good. But it's like the skin. It's not like the skin at all. That's, you know, that's your thing. You gotta give it up. It is very much, I I think. If you peel the skin off, you're peeling off that superficial layer. It's like, here's a superficial layer. When you take off my shirt Yeah. When you skin an animal, it's that white pearly stuff. It's all of that, but you see, if you say it is the skin, you're confusing. You're you're getting yourself bald up somatically because the skin has all kinds of glands and so forth, and that fascia doesn't have it at all."
From a 1975 Boulder session, Asher pressing back against the suggestion that the superficial fascia is the skin:
The deeper point Asher keeps pressing is that the layers, however we name them, are not actually separate. They are one thing embryologically — bone, fascia, connective tissue all derive from mesoderm — and one thing functionally. The practitioner who thinks of them as discrete units stuck together by attachments has misunderstood the tissue. The right picture is of a continuous medium that has differentiated into recognizable regions, not of separate sheets glued to each other.
"I mean, this is all one thing right here for sure. And the bone look. You can trace right from the bone out to here if you want. In fact, the bone is probably wrapped in the fascial plane. Now don't forget that you're talking about stuff which develops embryologically from the same layer. Right. All of this stuff develops from the mesoderm. The bone develops from the mesoderm. The fascia develops from the mesoderm. The connective tissue develops from the mesoderm. So, again, when you're talking about it connects here, it connects there, the dewstid connects there, it was there, and it developed from there. Don't you hear the difference? Don't let that guy lead you astray. Absolutely. Chuck, I in support of that deep layer of superficial fascia as being an important thing, Often what happens is, this is my idea, is that when you do dissections, you'll see little strings and strands running under that deep superficial running all kinds of random ways."
Asher continuing the same Boulder exchange, pressing the embryological point:
There is a clinical observation that follows from this. Asher points out that when the practitioner is working on someone, the client will often feel a sensation in a part of the body distant from where the hand is — a referred tug, a release in a place the practitioner has not touched. Asher's hypothesis is that this is the deep layer of superficial fascia letting go, the little strands and fibrils that run in all directions under the surface communicating the change. It is a mechanism of sensation, he says, that the medical model has not considered.
"Chuck, I in support of that deep layer of superficial fascia as being an important thing, Often what happens is, this is my idea, is that when you do dissections, you'll see little strings and strands running under that deep superficial running all kinds of random ways. And often when you're working on somebody and some really distant part wrapping around somewhere, they'll feel this little twin somewhere else, and it's my suspicion that that's what they're feeling. It's that that little strand letting go. Could be these things right here? Could be fibrils. It's but it's a it's a mechanism of pain that that the medical model has not at all considered as far as I know. You mean the the the fascial connection? Those those super deep superficial fascial strands Yeah."
Asher offers his clinical hypothesis about referred sensation:
Compartments and the architecture of the limb
The deep fascia's most teachable feature is the compartment. Asher returns to this image across multiple sessions: the fascial plane is the boundary that defines a functional group of muscles, and the practitioner works either the individual muscle, or the compartment, or the wrap around several compartments together. The hand learns to feel which level it is at by the texture of the resistance — the loose slide of the superficial layer, the strong investing layer underneath, the tighter septa between compartments. This is what makes the second-hour work on the leg coherent: it is not arbitrary geographic exploration, it is a passage through a known architecture.
"around the whole bunch. In other words, we're wrapping around the whole biceps here. And then sometimes we're wrapping we're working the sleeve that goes around that whole thing. We're going around there's a sleeve then that covers all these flexors. And then that okay. So that would be, for instance, one of these major cell one of these major compartments. And then sometimes you work on the total compartment. The compartment goes all the way around the whole thing. And that is made up of two layers. Your two some people lay I label it the epidermal layers of fascia, and they will call it the two superficial layers. Superficial, superficial, and deep superficial.
Asher in the 1975 Boulder class, walking the practitioners through the layered structure of a limb:
The compartmental view also clarifies a question that comes up repeatedly in the transcripts: what is the fascial plane, exactly, and what is just the wrapping around a muscle? Asher draws a distinction the practitioners find slippery. The investing layer around a single muscle is part of the muscle, in his usage; the fascial plane proper is the boundary between functional groups, the compartment wall. Other practitioners use the terms differently. The disagreement is not resolved in the archive, but it is named clearly enough that the practitioner learns to ask which sense is in play in a given conversation.
"Call the fascial planes. In here are inserted muscle. A muscle I consider to be made up of connective tissue and say a contractile element. So I don't call the outer layer of the muscle a fascial plane. I call them a muscle. The outer layer is a connective tissue layer, which may lay up against this layer and may lay against another muscular. Here's two muscles, but there is no fascial plane say between them there, Although these over here may be separated by a fascial plane. So you're defining the fascial plane as sort of the definition of the compartment that the muscles are contained in. So you've got functional groups defined by planes or by planes. Sometimes you don't really have a separation. I mean, that is continuous with the wrapping around the muscle. Oh, yeah. You're saying Jeff, are you saying that the investing fascia of the muscles doesn't form a fascial plane?"
Asher in another 1975 Boulder session, distinguishing fascial planes from muscle investing layers:
The neck as a special case of layered fascia
The neck is the place where the superficial-versus-deep distinction becomes most operationally consequential, because the neck's fascia is arranged in three distinct lamina rather than the simpler two-layer structure of much of the trunk. In one of the earliest recordings in this collection, from 1971-72, Ida walks the practitioners through the fascia of the neck using Charles Singer's classical anatomical text as a guide. The teaching is deliberate, even formal — Ida is presenting Singer's framework as the right way to think about how the neck's compartments separate the divergent mechanical functions of the head, the vertebral column, the shoulder, and the upper digestive tube.
"I want we're going to go now to the deep fascia that ended my consideration with superficial fascia of the neck. And I was struck by the clarity with which Singer has stated the separation of the various functions and compartments of the neck. So I'm going to read a paragraph from page 13. He says, The muscles that cause the movements of the vertebral column, the head, the shoulder, and the upper part of the intestinal tube form independent mechanical systems. But these muscles are crowded on the side of each other or over each other in the region of the neck. In order to permit these divergent mechanical function and to properly accommodate these various systems, the fascia profunda forms a complicated system of compartments. The walls of these compartments can best be described as forming three layers which unite with each other in the different regions."
Ida in a 1971-72 advanced class, citing Singer on the layered fascia of the neck:
The same 1971-72 session names another structural fact about the neck: the superficial fascia of the neck continues from the superficial fascia of the head, anchored above the nuchal line, and then divides functionally between the back of the neck (the nape, where the fascia is continuous with the back) and the front and sides, where there is a kind of inguinal-ligament-like boundary that stops fluid flow and pushes transmission into the deeper lamina. This anatomical detail is what makes seventh-hour work coherent — the practitioner is moving between three specific lamina, not stretching some vague "neck tissue."
"And that the reason that he makes this distinction is that the muscles in the back of the neck, the nape of the neck, are really muscles at the back, a lot of them. And that you'll see that when you look at the fascia, that the fascia goes down the back here and you don't have that when you move anteriorly. The neck tends to be stopped at it's almost like there's an inguinal ligament and we'll get into that that runs across here in the front and although there's transmission downwards there's that boundary. That's the lamina profunda, isn't it? Well, It's just underneath the superficial fascia. Yeah. And it joins, it comes back here to the levator and trapezius. Right, it's the levator and the trapezius form that border back here. But there is, and we'll get into it, there is a line, there is a thickening and a fusing of those lamina that runs like this that acts almost as an inguinal ligament that stops fluid flow and then the transmission goes in that second layer where it goes down into the median spine of Okay, the in the back, the superficial fascia blends with the fascia of the back as it comes down the head. In the front, it comes over the clavicle and is continuous with the superficial fascia on the ventral side of the trunk. Now there's this strange muscle platysma which is just under the superficial fascia and is covered by a very thin paramesium and separates the superficial fascia from the external lamina of the deep fascia. Now I'm going to talk about lamina because this fascia in the neck is in three distinct layers. So when"
Ida in the same 1971-72 series, mapping the boundary that separates nape from anterior neck:
Working between the layers: what the practitioner feels
All of the anatomical specification is in service of one practical question: what is the practitioner's hand actually doing between the layers? In the 1974 Open Universe classes, the teaching shifts from anatomy to phenomenology. The practitioner reports a warming, a melting feeling at the place where the layers were stuck. Hardened material — a fluid that became solid after injury or illness and was not reabsorbed — softens and starts moving. The superficial-versus-deep distinction is no longer just textbook; it is the difference between which stuckness the hand is releasing.
"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 describing what working between the layers feels like, in a 1974 Open Universe class with Ida present:
The same Open Universe session is where Ida names one of her most enduring images of what fascia stuckness is and how movement returns. The stuckness, she says, is not abstract — it is fascia between layers that has hardened, that has lost its slide. The whole work, including the first-hour superficial work and the deeper hours that follow, is about restoring that slide so that the muscles do their own work instead of being grouped together in glued-up extrinsic masses.
"Like there's an in between force between my body and your hand and that it is moving. It's just moving by itself. Now you can feel that I can feel that his spine is dropping back more, especially through this area now. As he breathes, there's more movement in his rib cage. You see fascia gets stuck between layers. Fascia is the covering of muscles, the envelope. The envelope of one muscle gets stuck on the envelope of another muscle. So we're ordering the connective tissue or the web. And one of our keys is the movement. And the clasp in these are the kind of places that I'm working on right now where doctor sees them from across the room. She'll say, now back there on the back by the fourth rib, go in there and get that. And there it is. Well, you can call there's where it's supposed to be worked on. It's the stuckness or the How can you see it?"
From the 1974 Open Universe class, the practitioner describes what becomes available as the fascia between layers releases:
The orange and the bag: fascia as the organ of structure
Two of Ida's most-quoted images for fascia come from the 1973 Big Sur class and the 1974 Healing Arts lectures. The first is the orange-skin image: scoop out the contents and what remains is a recognizable orange, because the skin and the internal connective tissue is what gave the orange its shape. The second is the broader claim that fascia is the organ of structure — the one tissue in the body whose job it is to determine the relationships in three-dimensional space. Both images underwrite the superficial-versus-deep distinction by giving it a purpose: the work distinguishes the layers because each layer plays a different role in determining the body's shape and relationships.
"factory go, but fascia is the stuff that keeps it from falling in on itself, falling in on its face, keeps you from falling on your face. It is your fascial body that supports you, relates you, and you know as with a child, you fool them sometimes by scooping out the material of the orange and leaving the skin and then putting the two heads together and you say to the kid now this is this is an orange and you see how long it takes that young ster to find out that it isn't an orange, that hits a ball of fascia. And so with with a a human being, in theory at least, you could scoop out the stuff that makes the factory go, the chemicals and so forth, and you would have left this supportive body of fascia. And it is this body which has had very little, almost no exploration in the sense that we have been giving to it. I remember sending somebody who came to me as a student and I set them the question of I set them to answer the question, what is fascia? She decided that was lots of fun. She'd go to the library."
Ida in the 1974 Healing Arts lecture series, developing the orange-skin image:
The Big Sur class from the previous year makes the same claim in different language. Fascia is the organ of structure — the tissue that has the job of holding the body appropriately in the three-dimensional material world. This is not medical-school doctrine. It was not taught in the medical schools as far as Ida knew, and any medical practitioner who would think it through would, she said, recognize that it is so. The implication for the superficial-versus-deep distinction is that both layers are part of one organ, performing different functions of one structural mandate.
"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."
Ida in the 1973 Big Sur advanced class, on the collagen system as the organ of structure:
Where the distinction gets revised: dialogue and disagreement
The terminology and the layered model do not arrive in Ida's teaching fully formed. The transcripts show her revising her own framings, soliciting her practitioners' challenges, and openly admitting when the classical anatomical categories do not match what the work requires. In a 1975 advanced session she pushes back on the very analytical move that produced the superficial-versus-deep distinction in the first place — the move of separating the body into named parts and treating them as discrete objects rather than as continuous tissue.
"Like if you're dissecting a brain, you can get yourself more balled up than any other fashion by trying, as you dissect the brain, to see the line of demarcation between these various parts of it. And the same thing is true down in the myofascial body, to try to see just where these, and yet, and yet, a great many modern surgeons are learning to not cut through the fascia, but to slide between the fascia to get where they want to go. And this is the modern progression nowadays. So that, actually, you have to use your imagination in many directions, and you seem to have a fairly good imagination, David. Your imagination of the analytical breakdown of this body and your recognition that your analysis is a way of getting to a higher level of abstraction, but not getting to a higher level of reality. Because when you separate that body into these higher level abstractions, you are not getting anywhere near the reality. You are getting further away from it. You are analyzing. You are not synthesizing. Now it takes an awful lot of thinking before this is really part of your mental process, and the best way that I know of to suggest your thinking is to turn you loose on some of this stuff, and get you to do the kind of tracing that gives you a greater reality of what David's talking about. What makes a muscle not an organ, but a myofascial unit? You see, these fascial planes have many reasons for being."
Ida in a 1975 Boulder session, warning against the analytical separation that creates the layer-categories in the first place:
And in a public-tape session captured in the same period, Ida acknowledges what every practitioner who has tried to explain the work to a new audience has discovered: most people have never heard the word fascia. They have no mental category for it. The educational task ahead is not just teaching the layers — it is establishing the existence of the tissue in the broader culture. The fascial planes of the shoulder girdle and hip girdle, she says, are still not well-mapped; what is needed is a book to which the practitioner could refer about how those planes run, in the way one refers to an anatomy text for the muscular patterns.
"I do think that sooner or later, someone of us has to be smart enough to really trace out facial patterns of the shoulder girdle and facial patterns of the hip girdle. Because you see this is what we've been dealing with. And then there is the problem of the connection between say the tenth rib and the crest of the ileum which is another fascial problem. But how do these hip girdle fascia fit together with the fascia that enwraps the obliques for instance? Now if the fascial patterns were as clear to us as the muscular patterns are, I think there would be a great deal less problem in teaching this if there were a book to which we could refer about how those fascial planes run as we refer back to our anatomies here as to how the muscular patterns run. It might be that it would be easier to turn our practitioners who understood they were dealing with facial bodies. You see, when you people get to the place where you go out and you give demonstrations, you can bank on the fact that you're going to have one or two people in the audience who are going to say to you, and how does this happen or what happens? And you say something about it happens by means of fascism. And there will be a great many people in the audience that you see haven't heard your word fascia because that this is an unfamiliar word to them. They not only don't know what fascia is, but they never heard that word and it means nothing to to them. Now all of this is part of the educational part process that lies ahead. It has nothing too much to do with the job, the immediate job that you have to do today."
Ida in a public-tape session, naming what the field still lacks — a clear map of the fascial planes:
Coda: layers as a working distinction, not a final taxonomy
What the archive preserves is not a settled doctrine about superficial versus deep fascia but a working distinction that Ida and her closest practitioners refined across years of teaching. The superficial fascia is the bag — two layers, sliding over the architecture beneath, the first thing the practitioner addresses, the layer where the first hour does its work. The deep fascia is the investing layer and the system of compartments and septa that organize the body's muscles into functional groups; it is what the recipe addresses progressively, hour by hour, as the deeper architecture becomes available to the practitioner's hand. The terminology is imperfect, the boundaries are fuzzy, the layers are continuous embryologically and functionally — and Ida, by 1976, is suggesting that the right vocabulary is connective tissue rather than fascia at all. The distinction remains useful precisely because it is a working tool rather than a closed taxonomy. The practitioner's hand learns the layers by working them; the vocabulary, in Ida's mature view, is whatever lets the hand keep working.
