The three locations are named precisely and the naming is anatomical rather than symbolic.
"Taoism points out that there are three gates in the du-mai where your chi often feels blocked during the earliest stages of cultivation. These are the tailbone gate at the coccyx, dorsal gate in the spine near the shoulder blades, and jade pillow in the back of the head near where the top of the spine meets the skull."1
Three points on one channel, evenly distributed along the spine.
The tailbone gate at the coccyx — the bottom, where the du-mai begins and where the rising wave is described elsewhere as felt most strongly.
The dorsal gate near the shoulder blades — the middle, and the region named separately as one of the neglected areas where the chi body first snags.
And the jade pillow at the base of the skull, where the spine meets the head.
Which is a route with three obstructions on it, and the qualifier says when they matter: during the earliest stages of cultivation. Not permanently — these are the beginner's blockages, and their prominence is a stage property.
And where your chi often feels blocked is a report about sensation, not a claim about anatomy. The gates are named by where practitioners get stuck, which is how a practical tradition would name them, and it is a different kind of claim from a structural one.
The value of the list is that it is checkable and finite. Three named places, on the back, in a known order. A practitioner meeting resistance can ask whether it is at one of them — which is more than almost any other marker in this material offers. See The River Chariot and the Pearl in the Shell.
The gates explain a phenomenon reported elsewhere without explanation, and the connection is worth making.
The River Chariot wave is described as strongest near the lower spine as it rises, and evening out by the time it reaches the head.
And the tailbone gate is the lowest of the three. A wave meeting its first and largest obstruction immediately after starting would be most felt there — and once past the gates, with less resistance ahead, it would flatten.
Which makes the intensity gradient a resistance gradient, and it is consistent with the general account: you feel the chi where it is meeting something, and the feeling disappears when the obstruction does.
Two things follow for a practitioner.
A sensation at one of the three named points is more informative than a sensation elsewhere. It is at a location the tradition predicted, in a stage where the tradition predicted it.
And the gates should stop being felt. If the intensity is resistance, then a cleared gate is a silent one — which matches the report that the rotation ceases to be felt within two or three days of opening, because the major obstructions have gone.
Which gives the three gates a lifecycle: prominent early, felt as blockage, then progressively quieter, then absent. The absence is the outcome, not a loss. See Never Block a Channel.
The uppermost gate gets more attention than the other two and its position explains why.
The jade pillow sits at the junction of spine and skull — the point where the du-mai leaves the vertebral column and enters the head.
Which makes it a transition rather than a segment. The other two gates are obstructions along a continuous run. This one is where the route changes character, from the spine's channel to the head's much finer network.
And the head is described everywhere in this material as the finest and most numerous territory — a garden of tiny channels, handled last in every cycle, the crown worked at the end.
So a wave arriving at the jade pillow is arriving at a bottleneck in a real sense: the passage narrows, the destination branches enormously, and everything above it is described as difficult.
The name itself encodes something. A jade pillow is a hard object placed under the head — dense, cool, unyielding, and exactly where the gate is. Which is the same naming logic as the stupa for the throat: a local object whose physical properties match the felt quality of the region.
And it recurs in the decode: Eurytion "probably refers to one of the chakra gates along the du-mai, such as the jade pillow at the back of the head."3 Probably and such as — two hedges in one sentence, which is the subject of the case study below. See The Throat Chakra and the Blue Neck.
The most instructive thing on this page is a decode that is attempted, supported by four independent clues, and then declined.
The clues assembled for Eurytion are unusually good.
"Eurytion was the son of Ares, who represents masculine yang chi, and the Hesperid Erytheia. He was born next to a river in the hollow of a rock, which suggests the skull. These clues taken together suggest a feature within the head such as a chakra along the route of the macrocosmic circulation. An obvious candidate at the back of the head is the 'jade pillow gate' of Taoism, which is an especially fine fit since Eurytion was a giant (meaning tall)."1
Four convergent lines. Parentage giving yang chi. A hollow in a rock, read as the skull's cavity. A Hesperid mother, placing the family in the head. And giant read as height, matching a gate near the top of the route.
That is more supporting detail than most identifications in this corpus receive, and the fit is good.
And then it is refused: "The herdsman Eurytion could represent many things in this story, so it would be dangerous to assert that he represents any phenomenon in particular. The best we can say is that he represents something along the du-mai and jen-mai which opens in this labor."2
Dangerous to assert — and the best we can say is the retreat to a claim the evidence actually supports: something on the orbit, opening here.
Which is the discipline the rest of the decoding project mostly lacks. The four clues would have carried a confident identification everywhere else in this material. Here they are judged sufficient for a location and insufficient for a specific gate.
And the reasoning is stated, which is rarer still: could represent many things — the fit is good and the space of alternative fits was never enumerated, which is the correct objection to every convergent-clue argument.
[n=1 REFUSED] — and the refusal is worth more than the identification would have been, because it shows the method's own sense of where its evidence runs out. See Don't Be Wed to My Interpretations.
Use the three gates as a location check and nothing else.
Do not work them. They are points on a channel, and concentrating attention on a point is the local-practice error — the chi arriving at a gate you have been forcing meets everything you never cleared above and below it.
Do use them to interpret resistance. If something feels stuck, ask whether it is at the coccyx, the shoulder blades, or the base of the skull. A stall at one of the three is the ordinary case for an early practitioner and is not a sign anything has gone wrong.
Expect the order to run bottom to top. The tailbone first, the shoulder blades next, the jade pillow last — which follows from the du-mai's direction and from the head being the finest territory.
Expect them to go quiet. If the sensation is resistance, then clearing removes the sensation. Losing the feeling at a gate is the gate opening, not the practice failing.
And weight the general practice toward the middle gate's region, because the shoulder blades are on the named list of neglected areas and the coccyx and skull are not. The dorsal gate sits in territory nobody attends to by default.
One thing not to do: treat this list as complete. Three gates on one channel is the beginner's map of one route — the du-mai is one of two on the orbit, and the orbit is one circuit among the seventy-two thousand channels named elsewhere. See Seventy-Two Thousand Channels.
It is worth being clear about what this kind of list gives a practitioner, because it is less than it appears and not nothing.
It does not give a technique. Nothing about knowing where the gates are tells anyone what to do, and the standing instruction is that nothing should be done.
It does not give a timetable. No duration is offered for any gate.
What it gives is a prior. A practitioner meeting resistance at the base of the skull knows two things: this location is expected, and others have been here.
Which is the fear-reduction function this material names as the reason the descriptions exist at all — knowing about these things so as not to be confused and think you are retrogressing.
And the value of a finite list is specific. Three named points is a set you can hold in mind. A sensation at one of them is confirmable; a sensation elsewhere is not disconfirming, since the map is admittedly partial — but the three carry information the diffuse descriptions do not.
Compare what most markers in this material offer: a phenomenon, a stage, and a warning not to pursue it. This offers a coordinate.
Which is why the Taoist gate-list has survived and propagated: it is the kind of thing a practitioner can actually use in the middle of a practice, and almost nothing else in the technical literature is. See The Rotation Is the Better Milestone.
The verb chosen for the gates is worth taking seriously because a different one would describe a different situation.
The chi feels blocked — not stopped, not absent, not failing to arise.
Which is a report of something present meeting resistance. A blockage presupposes a flow. Nothing is blocked in an empty pipe, and the sensation the gates are named by requires the chi to be there and to be pushing.
Two consequences follow, and both are encouraging in a way the page does not say.
A felt blockage is evidence of activity. A practitioner stuck at the tailbone gate has something arriving at the tailbone gate — which is more than a practitioner with no sensation anywhere has, and the frustrating experience is the better one.
And a blockage is a relationship rather than a state. It is a function of how much is flowing against how much is obstructing, which means it can resolve from either side — more flow, or less obstruction — and both are downstream of the same general practice.
Which also explains why the gates are an early-stage phenomenon. Early on there is little flow and much obstruction, so the ratio is bad at every restriction. Later the flow is larger and the restrictions are worn down, and the same points stop announcing themselves.
The image the material uses for the whole process fits exactly: nearly all chi energies initially go towards dredging the channels. A dredger meets its worst resistance at the shallowest points and works them until they are not shallow.
So the three gates are the shallows of the du-mai — named because that is where the dredging is hardest and slowest, and where a practitioner will spend the longest wondering whether anything is happening. See Never Block a Channel.
One of the three is in territory this material separately identifies as neglected, and the coincidence is worth stating.
The dorsal gate is in the spine near the shoulder blades.
And the shoulders are on the named list of regions people do not attend to — feet, hands, buttocks, ribs and shoulders, given as the areas to weight deliberately inside every practice because attention does not go there by itself.
They are also where the inner chi body first snags. The turtle straining from its shell describes exactly this: on the first ejection, the whole structure seems stuck in the buttocks and shoulders.
Three independent observations converging on one region. A du-mai gate, a neglected area, and the site of the first ejection's resistance.
Which is either a structural fact about the region or a fact about attention, and the second is the simpler account: a stretch of the body that receives no attention accumulates obstruction, and accumulated obstruction shows up as a gate, as a snag, and as a place worth naming on a list of neglected areas.
The practical consequence is that this gate, uniquely of the three, has a stated remedy that is not local work. The neglected-regions instruction is to weight attention toward the shoulders inside whatever full-body practice you already run — which addresses the region without concentrating on a point.
The coccyx and the jade pillow have no equivalent. Neither appears on any neglected-regions list, and nothing is recommended for either.
Which suggests the three gates are not one kind of thing, and the page treats them as one. [SPECULATIVE] — the convergence is assembled here rather than stated. See The Turtle Straining from Its Shell.
Evidence. [PRACTITIONER SOURCE]. 🚩 SECONDARY WITHOUT PRIMARY — no Taoist text is cited for the three gates, and the terms are given in English translation without originals. 🚩 SINGLE SOURCE. [PLAUSIBLE — needs corroboration] — the three-gate scheme is widely attested in Taoist internal-alchemy literature and none of that literature is engaged here.
Tension — a refusal on one page and confidence everywhere else. The Eurytion identification is declined as dangerous on four convergent clues. Identifications elsewhere in this corpus are made on fewer. No principle is offered for when the refusal applies.
Tension — probably, and then dangerous. Two adjacent passages give the jade-pillow reading as probable and as too dangerous to assert. Which is a change of position within a page, and the second is the considered one.
Open question — what does a gate feel like as it opens? The blockage is described and the passage is not. No phenomenology is given for the transition at any of the three.
Open question — do they recur? The gates are named as blocking during the earliest stages. Whether they re-present in later cycles, as the crown is said to, is not addressed.
Open question — why three? The number is given as traditional and no reason is offered for these three points rather than others along the same channel.
Two dispositions toward identification run through this material and this page contains both, adjacent, on the same figure.
Assert the reading. The garden is the crown chakra. Jacob's ladder is the three channels. Geryon's three bodies are three chakras. Confident identifications, made on convergent resemblance, throughout.
And decline the reading. It would be dangerous to assert that he represents any phenomenon in particular. The best we can say is something along the du-mai and jen-mai which opens in this labor.
The refusal is better reasoned than any of the assertions, and its reasoning generalises: a figure could represent many things, and a good fit does not establish uniqueness unless the alternatives were enumerated.
Which is a standard the confident readings do not meet, and the page does not notice that it has articulated one.
The convergence is on what the evidence supports in both modes: a location and a stage. Even the declined reading yields something on the orbit that opens in this labour — and that is what all the confident identifications actually establish too, with the specific organ or chakra being the part that exceeds the evidence.
Which suggests the honest general form for this whole decoding project: the stage and the region are readable; the specific structure is not — and this page is the one place that says so. See You Cannot See a Chakra's True Shape and Iconography as Attainment Record.
Epistemic Discipline and Noise Filtering — behavioral mechanics.
The Eurytion refusal is an act of epistemic discipline, and the strategic literature has the general form of it — including why it is so rarely performed.
The principle: do not get drawn into irrelevant conflicts. Not from weakness — responding is a choice, and some choices spend resources on things that do not matter. The discipline is distinguishing signal, information that bears on the outcome, from noise, which is everything else. And the image: the barking dog is not the threat; it is the distraction. A true threat does not bark; it acts.
Three things fall out.
A good-looking clue is a barking dog. Eurytion's four convergent details are attention-grabbing precisely because they cohere — and coherence is what a false pattern also produces. The discipline is declining to engage a pattern that is compelling and does not bear on anything checkable.
And the cost of engaging is not zero. In the strategic case, responding to a barking dog spends resources. Here it spends something more expensive: an identification entered into the record, which the next reader inherits as established and builds on. The decoding project's errors compound, because every confident reading becomes a premise for the next.
The third is why the discipline is rare. Ignoring a barking dog looks like weakness, and refusing a well-supported identification looks like failure of nerve. The reward structure runs the other way in both cases — a confident reading is publishable and a refusal is not, and the same is true of a strategist who declines a visible fight.
The insight neither field produces alone: epistemic discipline is invisible when it works. A refused identification leaves nothing behind — no page, no finding, no contribution — which is why a corpus of six hundred pages contains one of them, and why the one it contains is the most methodologically valuable passage in it. The discipline is not scarce because it is difficult. It is scarce because it produces no artefact.
The unresolved thing is whether the three gates are structures or statistics.
The passage names them as where the chi often feels blocked, which is a claim about frequency of report — a statistical fact about practitioners.
And it names them as gates, which is a claim about anatomy — features of the channel that exist whether or not anyone is stuck at them.
These are different, and they predict differently.
If they are structures, everyone has them, everyone passes through them in the same order, and the three are a permanent feature of the route. The list would be a map.
If they are statistics, the three points are simply where obstructions most commonly accumulate — for postural reasons, for reasons of neglect, for whatever makes the coccyx and shoulder blades unattended in most people. The list would be a demographic finding, and a practitioner with a different history might stall somewhere else entirely.
The second reading is better supported by everything around it. The shoulder blades appear independently on the list of regions people neglect. The neglected-regions instruction exists because attention does not go there — which would produce accumulated obstruction at exactly that point, in most people, for a reason having nothing to do with channel architecture.
And it would explain why the gates are an early stage phenomenon. A statistical blockage clears and does not return. A structural gate presumably would.
The stake is whether the list is worth checking against. As a map it is authoritative and a stall elsewhere is anomalous. As a statistic it is a useful prior and nothing more — and a practitioner stuck somewhere unlisted has learned only that they are not typical.
