Water shimmering on a road that turns out to be dry. Then smoke — a small cloud with tiny dots of blackness swirling in it. Then a ball of sparks below the chest, around the navel, like fireflies at night. Then a small steady flame, the way a butter lamp burns in a room with no draught.
Four images, in that order, and the order is the whole point:
As the chi enters and dissolves in the sushumna central channel, the special inner signs of this progress will sequentially include a vision like that of a mirage, a smokelike appearance, a vision like the flickering of fireflies, and a vision that can be compared to the light which issues from a butter lamp.1
Each one is tied to an element handing over to the next. Earth dissolves into water, and you see the water-mirage — because the water element becomes dominant in a relative sense.1 Water into fire, and you get smoke, sometimes described as a vision of whispy blueness. Fire into wind, and the sparks arrive. Wind into mind, and there is the lamp.
At the lamp, something else happens that is not visual at all: the conceptual mind starts to go quiet, and the person who has reached this stage will notice that they can stop breathing.1
Notice the shape of the series before anything else about it. Mirage, smoke, sparks, one small flame. Each image is fainter, smaller and less structured than the one before it. Whatever else is going on, the sequence is a graded fade.
Fourteen pages earlier, the identical four appear — in a passage about dying.
First, when the element of earth dissolves into water, the nadi-knot at the navel disintegrates… the body feels heavy, consciousness fades, and an experience that is like a mirage appears. Next, when water dissolves into fire, the nadi-knot at the heart disintegrates… the mouth and nose dry out, consciousness is restless, and an experience resembling smoke arises. Third, when fire dissolves into wind the nadi-knot at the throat disintegrates… the body temperature grows faint, perception vacillates, and an experience that is like fireflies arises. Fourth, when wind dissolves into consciousness the nadi-knot at the secret place disintegrates… the breath stops moving through the nostrils, the consciousness is slightly confused, and a slight appearance of light appears.3
Same four, same order, same elemental logic. One list is what happens to a meditator whose chi is entering the central channel. The other is what happens to a body that is shutting down. Bodri states the connection directly: a dying practitioner will experience many visaya that are similar to the same visaya experienced when the chi starts entering the sushumna central channel.3
That is the load-bearing claim of the whole area, and it is what makes the rest of the system make sense. If dying runs this sequence and meditation runs this sequence, then meditation is a rehearsal for dying — which is exactly why the Tibetan material treats sleep, dream and death as one curriculum. If he can master the Four Voids of Sleep, he can be assured of recognizing the Four Voids at the time of death. For him, death is a very helpful step on the Path.3
There is a practical claim attached, and it is the one externally testable thing here: when a person is dying, their left, right and lower chi mai are all changing, so an experienced practitioner can observe these changes and know how much time they will have before death.3 Somebody could have kept that record. Nobody appears to have.
The four signs are the warm-up. What follows is a second four, and they are not visions of objects but of the sky.
Tsong Khapa, in the passage Bodri quotes:
This is the experience of the vision known as "appearance." The inner sign is of whiteness, like seeing moonlight in a cloudless sky. The consciousness of "appearance" then dissolves into the second emptiness, known as "very empty." … The inner vision is of a yellowish red light, like that of the light at sunrise. This dissolves into the third emptiness, "the great emptiness"… The inner vision is of utter darkness, like that of a night sky pervaded by thick darkness. The person has a sensation of swooning and loses consciousness. After this the person emerges from the darkness and the state of mindlessness, and arises into the experience of "utter emptiness," also termed "the clear light." The vision is of a color like the blending of the lights of sun and moon in a sky free from all darkness, like the clear sky at early dawn.2
Stop at the third one. The person has a sensation of swooning and loses consciousness.
A stage of the path is a blackout. Not a metaphor for one — the text says loses consciousness, and then says the person emerges from the darkness and the state of mindlessness. There is a rung on this ladder at which nobody is home, and it is not a failure state. It is the third of four, and you have to go through it.
Almost nothing else in the book has this shape. Everywhere else the value of an attainment is that awareness persists into a place where it usually doesn't. Here awareness stops, and the scheme counts it anyway.
Look at the four sky images as a set: moonlight, sunrise, deep night, dawn. Every one of them is borrowed from a day. None of them is in the order a day comes in. Moonlight then sunrise is right; sunrise then thick darkness is not; thick darkness then early dawn puts you back at the start.
So the imagery is not a diurnal metaphor, even though it is built entirely out of one. The sky terms are indexing something else and using the day as a vocabulary of brightness, not as a shape of time.
Which is worth noticing because a reader will supply the day automatically. It reads like a night passing. It isn't one — the third stage is a hard interruption, a going-out, and the fourth is not a continuation of the third but a re-entry after it. The imagery smooths over the one place where the sequence actually breaks.
The same authors set the whole sequence out again in an earlier book, and the second telling adds three things — one of which contradicts the first. The caveat comes first, because it is the most usable line anywhere near this material. You should not be too particular about these signs, because the sick and the mentally ill can also experience these states.6 The mirage, the smoke, the sparks and the steady lamp are not proprietary to practitioners, and nothing is offered for telling one population's version from the other's. The Zen response is given in the same breath: ignore the whole class of transient phenomenon rather than get attached to it.
Then a caveat on the last empty, which is the one a practitioner most wants to be finished at. The clear light here is not the true clear light of self-realisation that even the worst karma can never extinguish. Far from being the true clear light, it is still a clear light with form.6 A stage described as utterly empty and free of every blemish is, on this account, still inside the aggregate of form.
And now the contradiction, which is not resolved anywhere. In one passage the white drops descend first and the vision is moonlight, at the stage called appearance. Then the red ascend and the vision is sunlight, at the stage called increase or proximity. Then the two meet at the heart and produce blackness.6
Roughly thirty pages later the identical sequence runs the other way. The red female drops collect first, giving a vision of redness and the mindset called appearance. Then the white male drops collect, giving a white light and the stage of proximity. Then the two collapse together into blackness.7
So both the colour order and the stage names are swapped between two accounts in one book. It's preserved here rather than resolved. A practitioner watching for white and getting red has no way to tell whether they are early, late, or reading the wrong page.
One corroboration runs the other way, and it's worth recording because this page previously noted the attribution as uncited. The Chuang Tzu line — that this stage is so balanced and so nice that it is "white" — appears in the earlier book too. Same moonlight stage, and again without a source.6
The earlier book also supplies a scriptural anchor the later one does not, for the final stage. From the Chudamani Upanishad: "When the red bindu moves upward by control of prana, it mixes with the white bindu and one becomes divine. He who realizes the essential oneness of the two bindus when the red bindu merges with the white bindu, alone knows yoga."6
The instruction attached to all eight stages is a single move, repeated:
One should understand the stages of these elemental dissolutions and be aware of them as they occur. As each of the four signs manifests, such as the mirage and so forth, one should contemplate how neither the self nor phenomena have any true existence whatsoever. Again, as the experiences of the four emptinesses manifest… one meditates on how neither the self nor phenomena have any true existence.2
And at the last one, a change of verb:
Especially, when the fourth emptiness manifests with the sign of a cloudless sky, which is the clear light mind in which the coarse sense of duality is pacified, one attempts to recognize and remain in meditation on it for as long as possible.2
Seven stages get contemplate that this is empty. The eighth gets stay here.
That distinction is doing real work and is easy to skate past. For everything up to the clear light, the phenomenon is not the object — the emptiness of the phenomenon is. You are being told, in effect, to refuse the content of each vision at the moment it arrives. Only at the last does the instruction become remain, because the last is not a vision of something.
Which means the whole eight-stage apparatus is built as a sequence of things you decline, ending in the one thing you don't. That is a coherent design, and it is the strongest internal answer to the obvious worry that a published list of expected visions is an invitation to produce them: the practice as written asks you to treat each one as empty the moment you get it.
Now the crack in the joinery, and it is specific. At p 569 the third sign — the fireflies — comes with the disintegration of the nadi-knot at the throat.3 At p 582 the same firefly vision appears below the chest around about the region of the navel chakra.1
Throat, or navel. The two passages give the same sign, in the same position in the same sequence, at opposite ends of the torso.
They come from different intermediaries. The death list is Bodri citing Erik Pema Kunsang's translation of Advice from the Lotus Born, pp 80–81. The meditation list is his own exposition, with the emptinesses quoted from Glenn Mullin's Readings on the Six Yogas of Naropa, p 130.2 3 Two source-streams, two anatomies, set down fourteen pages apart as one scheme. No reconciliation is offered, and a practitioner cross-referencing the two chapters has no way to know which body they are in.
To his credit he flags that variation exists, in general terms:
Different Tantric systems describe these signs in a slightly different order and fashion, and you can research these differences and correspondences through the various references that have been given.2
That is an honest disclosure and it is also a delegation. The disagreement is named, two further books are supplied — Dhargyey's Kālacakra Tantra and Mullin's The Practice of Kālacakra2 — and the reader is sent to do the collation that the comparative project exists to do. The book's whole method is putting schemes side by side; here it hands the side-by-side back.
Hour two of a long sit and the visual field has stopped being black. There is a shimmer in it. Water on a road. If you have never read any of this, what happens next is that you get interested, the interest wakes you up, and it goes. That is the ordinary outcome and it costs nothing.
If you have read it, something more complicated happens. You recognise the mirage. And recognition is a small, bright, extremely satisfying event — I know what this is, I am at stage one — and it, too, wakes you up, and it, too, goes. Except now the loss means something. Now you have slipped back down a ladder.
So you go looking for it again the next night. And here is the part the instruction is designed to prevent and rarely does: you now know what stage two looks like. Smoke, with little black dots swirling. You have the description. You are two hours into stillness with a quiet visual system and a specification.
The text's countermeasure is the contemplation, and it is well aimed: as each sign manifests, hold that neither it nor you has any true existence. Not observe the mirage — refuse it while it is in front of you. Done properly it strips the recognition of its reward, because there is nothing to have arrived at. Done improperly — which is to say, done by somebody who wants to get on — it becomes a formula muttered over a checklist. Mirage, empty, tick.
And then stage three arrives and you black out, and you have no idea whether you passed through the great emptiness or fell asleep. Nothing in the account distinguishes those from the inside, because from the inside neither of them has an inside.
The most interesting sentence in this material is the one that demotes it, and it is Bodri's own:
The descriptive scheme of chi entering the central channel is one more, albeit purely technical means for rating your progress at a certain lower level on the cultivation path.2
And immediately after: these various signs or "marks" are only signposts to help signify preliminary chi mai achievements, for afterwards there are even more advanced stages of spiritual progress to be expected.2
That is unusual and worth crediting. The most visually spectacular material in the book — the eight-stage dissolution, the clear light, the death-moment recognition that Tibetan Buddhism is famous for — is labelled preliminary by the man presenting it, in the paragraph presenting it. He does not need to be pushed to it. There is no defensive hedge; it is stated as a fact about where the scheme sits.
Three consequences follow, and the third is the one that bites.
One: it makes the scheme usable rather than aspirational. A signpost you have been told is a signpost cannot be mistaken for a destination. This is the fn 518 position — the stages as rest stops, verifications and motivational assists5 — delivered in the body text for once, ninety pages before the footnote that generalises it.
Two: it explains the tolerance for variation. If the scheme is a technical rating instrument at a low level, then different Tantric systems ordering the signs differently is a minor inconvenience rather than a doctrinal crisis, and delegating the collation to two further books is a proportionate response. You do not need the thermometers to agree to three decimal places if you already know you are measuring the shallow end.
Three, and this is the awkward one: it undercuts the death claim it is attached to. The reason the eight stages matter is that they are supposed to be the same stages a person passes through while dying — death being the sixth consciousness moving to a new place, with a moment in it where recognition is possible4 — so that mastering them in meditation is preparation for the one event nobody gets to practise. That is not a low-level claim. It is the largest claim in the chapter, and it is resting on an apparatus its author has just rated as preliminary.
Both cannot be fully true. Either the sequence is minor technical scaffolding, in which case rehearsing it buys less at the deathbed than the framing implies, or it is the map of the terminal event, in which case purely technical and a certain lower level are the wrong words for it. Bodri does not choose, and nothing in the surrounding pages forces him to, because the two statements are eleven lines apart and pointed in different directions.
Strongest support. The internal architecture is genuinely well-built. The four signs are a graded fade — each image fainter and less structured than the last — which is what you would expect from a real perceptual process rather than a list assembled for symbolic effect. The instruction is consistent across all eight stages and changes exactly once, at the only stage that is not a vision of something.2 And the self-rating as preliminary2 is a rare and creditable piece of scale-honesty in a book that mostly rates other people's traditions.
The tension the source does not close. Purely technical… a certain lower level against the claim that this same sequence is what a dying person passes through, mastery of which secures recognition at death.2 3 The demotion and the death claim are printed together and are not compatible at full strength.
A second tension, on anatomy. The firefly sign is placed at the throat knot in the death list and below the chest around about the region of the navel chakra in the meditation exposition.1 3 Two intermediaries, two body maps, no reconciliation, fourteen pages apart.
A third, on the blackout. The third emptiness includes a sensation of swooning and loss of consciousness.2 Nothing anywhere distinguishes that stage, experienced from within, from ordinary sleep or a faint — and the framework elsewhere is at pains to rule out inert absorptions. The one rung that cannot be self-reported is the one nearest the top.
A fourth, on citation. The Tsong Khapa passage reaches the reader as Bodri citing Glenn Mullin's Readings on the Six Yogas of Naropa p 130 — a Western anthology, not Tsong Khapa's text2 — and the death sequence as Bodri citing Erik Pema Kunsang's Advice from the Lotus Born rather than a Tibetan source directly.3 The Chuang Tzu attribution (that he called this stage white as his literary way of describing it) carries no citation at all.2 Standard compendium habit throughout: the intermediaries are named, which is more than the mismatch cases elsewhere in the book manage.
And the standing scope limit. Everything here sits on a ladder footnote 518 calls false stages, whose three real jobs it names as rest stops, verifications and motivational assists.5 Uniquely in this zone, the body text agrees with the footnote.
Open questions. An experienced practitioner is said to read a dying person's chi mai and estimate time remaining.3 That is cheap to record, obviously falsifiable, and would be the strongest evidence in the entire corpus. Has anyone ever kept the log?
Read with Dissolution in Strict Order, the two systems agree on the thing that matters most and were built continents apart: death is a procedure with a fixed sequence, not an event that befalls you. That page's Yudhiṣṭhira executes an order that cannot be skipped or reversed; this one's dying practitioner passes through knots in a fixed sequence and can be timed by an observer. Neither tradition treats the order as negotiable, and the convergence is on the ordering rather than on any of the contents.
Against Jaḍa Samādhi and the Biofeedback Problem, the third emptiness is a real problem. That page's whole concern is absorptions that look like attainment from outside and contain nothing — and here is a canonical stage which, by its own description, involves swooning and the loss of consciousness.2 The scheme has no test that separates the great emptiness from an inert blank, and the burden falls hardest exactly where the practitioner cannot report. With Dream Control as a Diagnostic this page supplies the content that page's argument needs. Sleep is the rehearsal because sleep runs the same four voids as death; without the identity of the sequences, dream yoga is a hobby rather than a preparation.
Set beside Gampopa's Episodes, the contrast is instructive. This page is the theory of central-channel signs; that one is the only place in the book where a teacher is shown reading such signs off a live student. The theory is elaborate and the recorded practice of it is fifteen brief consultations — which is a fair summary of the evidential situation across the whole area.
And against Never Guide the Chi, the collision is head-on and neither page resolves it. That chapter says the chi entering the central channel is not something to be aimed at, and that published records of phenomena become imitation scripts. This one publishes eight of them in order with descriptions detailed enough to visualise. The contemplation instruction is the only defence offered, and it is offered here rather than there.
What a mind produces when you take its inputs away — Hebb's Sensory Deprivation Experiments. Healthy students, goggles, gloves, white noise, nothing to do, good pay. The plan was six weeks; most could not last three days. What they got was anxiety, disordered thinking, hallucination — and, the detail the intelligence services cared about, a striking rise in suggestibility.
Put that beside a practitioner two hours into stillness, eyes closed, body unmoving, breath minimal, attention withdrawn from every channel it normally rides. That is the Hebb chamber, entered voluntarily and maintained for years. The prediction falls out immediately: a deprived visual system generates content, and the content is faint, unstructured and luminous — shimmer, smoke, points of light, a steady low glow. Which is, item for item, the four signs.
What the pairing gives that neither side supplies alone is a way to read the cross-school variation that Bodri discloses and does not explain. If the class of phenomena is produced by the deprivation, then every contemplative tradition that sits still in the dark should report faint luminous formless visions — and they do, which is why the comparative sweep works. But the specific list and its order would then be supplied by something else, and Hebb names the candidate: deprivation raises suggestibility, and the practitioner has been handed the expected sequence in advance, by name, in order, with descriptions precise enough to picture. The system tells a maximally suggestible subject what they are about to see, and then treats the match as confirmation. Different Tantric systems publishing slightly different orders, and their practitioners reporting slightly different orders, is exactly what that predicts.
Two things keep this from being a debunking, and both matter. Hebb's students fell apart in days; contemplatives sustain the same input reduction for decades and report the opposite affect, so the deprivation account predicts the phenomenology and not the equanimity — something else is doing that work. And the tradition has, in the contemplation instruction, an unusually well-aimed countermeasure: as each of the four signs manifests… contemplate how neither the self nor phenomena have any true existence.2 Refusing the content of a vision at the moment it arrives is precisely the move that would break a suggestion loop. Whether anyone actually manages it under the pull of recognising their own stage is a different question, and it is the one the eight-stage list makes hardest to answer.
One handshake. A second — that a sequence which both meditation and dying run makes rehearsal possible for the one unrehearsable event — is the page's own argument, and pairing it outward would restate rather than extend it.
Sharpest implication. Sitting still in the dark is an input-deprivation protocol, so the class of vision it produces is predictable from physiology alone — which means a tradition's published sign-list is not evidence of what the state contains but a specification handed to a subject the same protocol has made maximally suggestible, and cross-school disagreement about the order is the fingerprint of that, not a scholarly detail.
Generative questions.
