Most writing about chakras gives you a diagram and a colour scheme. This gives you a measurement.
Firstly the central channel, avadhuti, is envisioned. It begins at a point four fingerwidths below the navel at the center of the body just in front of the spinal column. To its right is the channel known as rasana, and to its left is lalana. These channels proceed up the body to the head, like pillars supporting the four chakras.1
Four fingerwidths below the navel. Centre of the body. Just in front of the spine. Three channels, one central and two flanking, running up to the head like pillars with four wheels strung on them.
And the lower ends do something specific: the lower tips of the side channels curve up into the base of the central channel. This is done in order to draw the vital energies into the central channel.1 The curve isn't decoration — it's a funnel, and the reason for it is stated.
Everything on this page is that kind of detail. Petal counts, colours, directions, syllable shapes, and a troubleshooting sequence for when it won't come clear.
Before any of the visualising, there's a motivation and then a posture, and both are given in order. The motivation is a formula to be repeated until it takes: for the benefit of living beings as vast in number as the measure of the sky I will achieve the state of a Buddha Vajradhara. For this purpose I now take up the practice of chandali, the inner heat yoga. And the instruction attached — meditate like this until your stream of being is infused with the bodhimind.1 Not once through. Until it's soaked in.
Then the body, item by item:
Visualizing yourself as the mandala deity, sit on your meditation seat, put on your meditation belt, cross the legs, and set the backbone erect. The neck is bent slightly forward, and the eyes cast downward at the angle of the nose. The tongue is held gently against the upper palate, and the teeth and lips set in their natural [closed] position. The body and mind are postured alertly, with the chest somewhat extended, and the hands in the meditation posture, placed just under the navel.1
Nine things, and several of them are the ones people get wrong. The neck bends slightly forward, not straight. The eyes go down along the line of the nose rather than closing. The tongue touches the upper palate. The chest comes out a little. The hands sit just under the navel — which is a few fingerwidths above where the central channel is said to start.
The belt is on the list too, which places this in the same family as the practices where a strap holds the posture together for long sittings.
Then the four chakras, each with a name, a shape, a Sanskrit syllable, a petal count, a colour, and a direction the petals point. At the navel is the wheel of emanation. Somewhat triangular, shaped like the syllable EH. Sixty-four petals, red, stretching upward.
At the heart is the wheel of truth. Somewhat circular, like the syllable BAM. Eight petals, white, extending downward.
At the throat is the wheel of enjoyment. Also circular, also like BAM. Sixteen petals, red, reaching upward.
At the crown is the wheel of great ecstasy. Triangular again, like EH. Thirty-two petals, multi-coloured, pointing downward.1
Read them as a set and the structure is deliberate rather than arbitrary. The two triangular wheels are at the ends — navel and crown — and the two circular ones are in the middle. The petals alternate direction: up, down, up, down. And the counts halve and double around the heart: sixty-four, eight, sixteen, thirty-two.
The pairing is stated as an instruction: the meditation should hold each of the two pairs of chakras within an according embrace of method and wisdom.1 So they're worked in pairs rather than singly, and the pairing is what the alternating directions are for. There's also an unusual admission of roughness, and it's worth keeping: here the arrangement of the petals is only roughly described. Details are not mentioned; but this is enough.1 Enough — a stated stopping point for how much detail is needed, in a passage otherwise made of exact numbers.
Then a sentence that changes what all of the above is.
(One visualizes the channels in this way for the purpose of meditation. But in fact) the channels continue on down, eventually coming to the tip of the jewel. Above the central channel comes to the point between the eyebrows, and the two side channels come to the inner passages of the two nostrils.1
For the purpose of meditation. But in fact. So the specification just given — three channels beginning four fingerwidths below the navel — is a device. In fact they continue down to the genitals, and above they end at the point between the eyebrows and inside the two nostrils. The version you visualise has been truncated at both ends on purpose.
The reason for the lower truncation is the funnel: you imagine the side channels curving up into the central one in order to draw the vital energies into the central channel. A visualisation that ran them all the way down wouldn't do that work.
And there's an aside that explains something otherwise unmotivated about meditation generally: the central channel really terminating between the eyebrows is why this is a common focus point for meditation.1 The brow point isn't chosen for symbolism. It's chosen because that's where the pipe ends.
The disagreements among teachers get printed inside the instruction, which is rarer still: not understanding this purpose, some teachers have said that the three channels just come to an end and stop at a distance four fingerwidths below the navel. Others have said that the two side channels just stop there.1 Two named wrong readings, both produced by taking the device for the anatomy — which is exactly the error the parenthesis exists to prevent.
The same authors' earlier book gives the four centres a set of foreign names, and the naming is the interesting part rather than the anatomy. The Sufis of Islam call them Teacher for the head, Mysterious for the throat, Secret for the heart, and Self for the navel.4 The American Hopi speak of the same four in their own tradition.4
Notice what those four Sufi names are doing. They are not locations and not organs. They describe a relationship — somebody who instructs you, something withheld, something private, and finally you. Which is a different kind of map from petal counts and fingerwidths, aimed at the same four places.
The argument attached to it is short and worth having. These four are called basic to cultivation technology, which is why every school emphasises them. And then the question: why bother with so many other chakras if you only need to discuss these four? That, in itself, is called a very important principle.4
The same passage says the seven are nowhere near the whole set, and the additions are oddly specific. There are several important chakras in the head that commonly go unmentioned. A real Bodhisattva does not leave his body through the crown, but through another head chakra a little lower down, towards the back of the skull.4 That is a claim about an exit route, made about the one being whose exit would matter most, and it moves the door off the spot every tradition marks.
The rest of the inventory reads like a body being mapped from the inside rather than from a diagram. After the brain channels open, the twelve cranial nerves act like antennae. Somebody who cultivates well can see countless sacred chakras floating in space and extending upwards above the head. And there are chakras at the tips of the fingers and toes, and on the various curved smooth surfaces of the body.4
One correspondence on this page gets independent confirmation there. The sweet saliva that descends in the state of ching-an is attributed to the lalana chakra in the throat, also called the kala chakra — and the same Judges 15:19 verse is quoted for it.4 Two printings, same attribution, and the same absence of any text older than the Bible cited for the anatomy.
Not everything in the specification is fixed, and the passage is careful about which parts aren't. The colours change with what you're doing. During the meditation for arousing the inner heat, the central channel should be seen as having the color of the flame produced by burning sesame oil. Prior to that point in the training, however, the right channel should be seen as being red, the left white, and the central channel bluish.1 So there are two colour schemes, and which one applies depends on which practice you're in.
The size isn't fixed at all: as for the size of the channels, this varies at times of meditating and not meditating. There is no certain, fixed size.1 Which is a strange thing to say about a pipe and a natural thing to say about something that appears under attention.
And at the four wheels the geometry changes: at the sites of the four chakras, the two side channels, rasana and lalana, wrap around the central channel, forming knots. Otherwise they all three run straight.1 Straight everywhere, knotted at four places — which is why the chakras are obstruction sites rather than merely stations.
The most useful thing here is what to do when the visualisation won't work, because it's a graded fallback with a stated danger. First, what you're aiming for. There are two aspects of the practice to which one should attend, namely, the radiance of the image and the meditative placement — you need both the radiant appearance of the envisioned channels and the firmness of the meditation.2 Brightness and steadiness, and either without the other is incomplete.
And a starting point is named: the most important site for the placement of one's awareness at the beginning of practice is the point in the region of the central channel where the three channels join.2 The junction, low in the body, before anything else. Then the ladder, in three steps.
Step one is the full practice — visualise the four chakras with their petal counts and fix the mind on them, and with persistence in the meditation the chakra petals become increasingly clear, and the mind more firmly placed upon them.2 Step two is the first fallback: if after considerable effort no clarity is achieved with the chakras, place the mind solely on the image of the three channels. Concentrate especially on the portion above the heart chakra.2 Drop the wheels, keep the pipes, and work the upper section.
Step three is where the warning is: if still no progress is forthcoming, prolonged application can incur dangerous obstacles. One therefore should relax the application, and place the mind instead on the point where the three channels join at the lower part of the body.2 That's the whole shape of the safety instruction, and it's the opposite of what a determined practitioner does. When it isn't working, don't press harder — pressing harder is named as what produces the dangerous obstacles. Relax the application, and move the attention down to the junction where you started.
Up and complicated when it's going well. Down and simple when it isn't.
Take the posture list literally, because most of it is checkable in ten seconds and most people have never checked. Backbone erect. Neck tipped slightly forward — not held straight, and not dropped. Eyes down along the line of the nose rather than shut. Tongue resting on the upper palate. Teeth and lips closed naturally. Chest out a little. Hands just under the navel. If four of those seven are wrong, you've been doing a different posture from the one the instruction describes, whatever else you were doing.
Then start where the instruction starts, which isn't where anybody wants to start. Not the crown, not the third eye — the junction low in the body where the three channels meet, four fingerwidths below the navel. That's named as the most important site for a beginner, and it's the same place you're sent back to when things go wrong.
Then hold the parenthesis in mind the whole time. What you're visualising is admitted to be a device: the channels are truncated deliberately so the side ones appear to curve up into the central one and funnel energy inward. So don't try to make the image accurate. Make it do the job. Somebody who reads the spec as anatomy will eventually notice that it doesn't match, and will conclude the tradition is confused, when the tradition said so on the same page.
And obey the fallback rather than your own persistence. If the chakras won't come clear after real effort, drop them and hold just the three channels above the heart. If that won't come either, the instruction is explicit: relax, don't push, and put the attention back at the junction low down. Prolonged application is what's named as producing dangerous obstacles — so the effort you're most inclined to make when it isn't working is the one thing you're told not to make.
Take the sharpest instance and follow what it does. You've been given an anatomical description of unusual precision. A channel beginning at a stated distance below a stated landmark, in a stated relation to the spine. Two more beside it. Four wheels with counted petals — sixty-four, eight, sixteen, thirty-two — each with a shape, a colour, a syllable and a direction.
Then, in a parenthesis: one visualizes the channels in this way for the purpose of meditation. But in fact they run further down and end elsewhere.1
So the specification is a working model, and it's labelled as one by the same text that supplies it, in brackets, mid-sentence. Three things follow, and they're all practical.
The first is that accuracy has been explicitly traded for function. The truncation isn't a simplification of the truth — it's a modification that makes the image do something the accurate version wouldn't, namely draw the energies inward at the base. The device is better than the description for this purpose, and the purpose is named.
The second is that the failure mode is documented with its casualties. Some teachers have said that the three channels just come to an end and stop four fingerwidths below the navel; others said only the side channels stop there.1 Those are teachers, not students, and both errors are produced by exactly one mistake: reading the working model as the anatomy. The parenthesis exists because that mistake had already been made and transmitted.
The third is the awkward one. If this specification is a device, then the other numbers in the same passage are candidates too. Sixty-four petals at the navel and eight at the heart are given with the same confidence as the four fingerwidths, and nothing marks which of them are descriptions and which are instruments. The passage even concedes roughness — the arrangement of the petals is only roughly described… but this is enough — without saying enough for what.
Which leaves a practitioner with a precise map, an admission that at least one part of it is a construction, no marking of which other parts are, and an instruction to use it anyway. That's not incoherent — it's what a working model looks like when the tradition is honest about it. It just means the precision carries less information than it appears to, and the counted petals are a specification for attention rather than a report about a body.
The strongest thing here is the fallback ladder, because it's a real safety procedure with a named danger and it runs against the practitioner's instinct.2 Three graded steps, with the instruction at the bottom being relax the application rather than persist — and the reason given is that prolonged application incurs dangerous obstacles. That's a procedure somebody could follow, and the direction of the advice is the tell that it came from watching people go wrong.
The parenthesis is the second, and it's unusual honesty. A tradition stating that its own diagram is a meditation device rather than a description, and naming two teachers' errors that came from missing it, is doing something most technical literatures don't.1
Two tensions stay open, and the first is a genuine conflict inside this corpus. This whole practice is a directed visualisation aimed at the body — you imagine channels, you place awareness at named points, you draw energies inward on purpose — and the surrounding material warns repeatedly against exactly that, on the grounds that the mind you're trying to settle is the mind doing the directing. Nothing here reconciles them. And the second: the specification is labelled a device in one place and given with exact numbers throughout, with no marking of which figures are which.
Flags. 🚩 SECONDARY WITHOUT PRIMARY throughout — the whole instruction reaches the reader as a quoted Tibetan practice text, with the colour scheme attributed at two removes to A Harvest of Oral Tradition Teachings quoting The Mystic Kiss Tantra.1 ⚠ The petal counts, syllable shapes and colours can't be checked by anybody who isn't already doing the practice, and the passage concedes the description is only roughly given. And the standing scope limit applies: all of this is channel-and-wheel work, low on the ladder that footnote 518 calls false stages.3 Everything is [POPULAR SOURCE].
Open question: the fallback says prolonged application produces dangerous obstacles, and doesn't say what they are. That's the one place a practitioner most needs the detail — what does it look like when this goes wrong, and how would you know before it did?
Two instructions about what to do with your attention and your body run through this corpus, and they can't both be followed. On the first, you build. Visualise yourself as the deity, construct three channels with stated dimensions, place four wheels with counted petals, fix the mind on them, and deliberately draw the energies into the central channel. Every step is an act of directed imagination aimed at a location in the body.
On the second, you don't touch it. Settle the mind and the channels perfect themselves; guiding chi with attention is the characteristic error; and the faculty doing the guiding is the one that was supposed to be going quiet.
Both are in the same book and neither is withdrawn. The nearest thing to a join is that this is presented as one tradition's method rather than as the method — and the fallback ladder is where the tension surfaces, because its final instruction is to stop applying, relax, and go back to the simplest possible placement. Read alongside Never Guide the Chi, the safety procedure inside this practice is the other position arriving as a correction from inside.
Behavioral mechanics — The Walkman Trick: Deliberate Limitation for Legibility. That page's finding is that a designed object is often made deliberately less capable than it could be, because a restricted version is legible and a complete one isn't. The limitation isn't a compromise forced by cost — it's chosen, and it's what makes the thing usable.
The truncated channels are that move applied to a mental image. The accurate version runs from the genitals to the brow and the nostrils. The version you're told to visualise starts four fingerwidths below the navel with the side channels curving inward — which is anatomically wrong on the passage's own admission, and does a job the accurate version couldn't: it makes the funnelling visible, so the attention has somewhere obvious to go.
What the pairing gives is a test for any instructional model, and it's answerable. Ask what the simplification makes possible rather than what it leaves out. A simplification that only leaves things out is a loss. A simplification that changes the shape so a specific action becomes obvious is a design, and the deviation from accuracy is where the design is.
And it predicts the failure mode precisely, which is the part this passage confirms. Somebody who doesn't know a model is designed will eventually notice the deviation and treat it as an error — which is exactly what happened to the teachers who concluded the channels stop at the navel. They were reading a designed object as a description, and the design's most useful feature looked to them like a fact about bodies.
Which suggests the general rule: when a model is deliberately limited, the limitation has to be transmitted with it, or the next generation will either correct it back into uselessness or defend it as literal. This tradition transmitted it, in brackets, and two teachers still missed it.
One handshake is the section here. A second would restate the same design point from a neighbouring page rather than open new ground.
Sharpest implication. The most precise anatomy in the book is labelled by its own text as a device for meditating rather than a description of a body — and the deviation from accuracy is the functional part, because truncating the channels is what makes the energies appear to funnel inward. Which means the counted petals and the stated fingerwidths are a specification for attention, not a report, and the precision carries less information than it looks like it does.
The edge left open. One part of the model is marked as a construction and the rest isn't marked at all. Sixty-four petals at the navel, eight at the heart, four fingerwidths below the navel — all given with the same confidence, and only one of them flagged. A practitioner has no way to tell which of the remaining numbers are instruments.
