Close your eyes and picture a room you haven't been in for twenty years. It comes. Nothing entered through your senses to produce it, and it arrived anyway, in detail, with a mood attached.
Something in you generates images without input. That faculty has a name in the scheme Bodri is working in, and once you have the name a great deal of otherwise scattered material lines up behind it.
The sixth consciousness has two aspects: (1) a clear consciousness that discriminates and comprehends ... and (2) a consciousness of images alone called the solitary consciousness or "du-yin" in Chinese.1
Clear discrimination is the half everybody knows — thinking, judging, comparing, the thing you use to read this sentence. The du-yin is the other half, and he glosses it directly: the "dark side" of clear discrimination, namely the "subconscious," is a realm of unfamiliarity.1 The word matters. Du-yin — solitary shadow, solitary head. Solitary because of the one property that makes it interesting.
The reason it's hard to fathom the du-yin is because the "solitary consciousness" can function by itself without the need of the first five consciousnesses. In other words, it is an aspect of the sixth mind that can operate on its own without the need of any information provided by the eyes, ears, and other senses.1
Every other consciousness in the eightfold scheme is tethered. Sight needs eyes, hearing needs ears, and ordinary discriminating thought works on what they deliver. The du-yin doesn't.
And Bodri draws the consequence immediately, which is where the page's claim about psi comes from:
Because it can operate independent of the senses, at times it can even jump out of the normal range of functions of the sixth consciousness and therefore go beyond the normal confines of space and time.1
That's the whole argument for psychic phenomena in this framework, and it's structural rather than mystical. A faculty constrained by sense organs is constrained by where those organs are. A faculty not so constrained has no obvious reason to be located anywhere in particular.
It's a neat step, and everything hangs on one link in it: that a faculty free of the senses is therefore free of the body's position in space and time. Cut something loose from sensory input and it can still be entirely the brain's own manufacture. That reading isn't taken up anywhere in the passage.
The scope of what gets filed under du-yin is the most striking thing on the page, and it's worth listing exactly.
The du-yin is the consciousness that functions during dreams, but it also functions in cases of insanity, during incoherence and even during certain states of meditation. Your "sixth sense" or ESP, instinct and even inspiration are all involved with this particular realm of consciousness.2
Dreaming, madness, confusion, meditative absorption, psychic impression, gut feeling, and artistic inspiration — one faculty. And a claim about who has more of it: artists, religious people and writers are likely to have a more highly active du-yin consciousness than the ordinary individual.3 Sit with what that classification does. It puts the poet's arriving line and the psychotic's voice in the same drawer, not as an insult to either but as a statement about the machinery. Both are the image-faculty running without sensory correction.
Which means the scheme isn't primarily a theory of psychic powers at all. It's a theory of unconstrained image-generation, and psi is one thing it is being asked to explain among several. Bodri's own attitude to its products is notably cool. On dreams: you shouldn't put too much faith in dreams but should rely on clear wisdom and analysis instead — even though the du-yin's range is really great and it can sometimes provide visions of heaven or hell, or even future events.1 Both halves in one sentence: enormous reach, low trust.
Because the du-yin is what runs during sleep, the scheme comes with its own classification of dreams — and Bodri is explicit that it's a rival to the psychological one, though he is unusually courteous about the competition: quite different than the current admirable one being etched out by modern psychology.7 Three categories, and their order is the interesting part.
Dreams of sickness and health. If you ate too much and are suffering during sleep, you may dream of a ghost or heavy object resting on your body; if the body is too hot, you may dream of an oven or fire.7
Dreams from ordinary thoughts mixed with deepest desires. Someone who wants to get rich dreams of the stock market; the extreme case he gives is sleepwalking.7
Dreams involving outside influences with actual spiritual beings — which he concedes are rare and rather hard to study using the methods of ordinary science.7 What's striking is which one comes first. The opening category is somatic and entirely material: indigestion produces the oppression dream, overheating produces the fire dream. That's a physiological account of dream content, offered without embarrassment, in a chapter that will shortly be discussing visions of heaven and hell.
And the mapping is specific enough to be wrong. Heavy object resting on your body is a recognisable and well-documented experience with a physiological trigger, and the claim that a particular somatic state produces a particular image class is the kind of thing that could be checked. So the practical instruction the scheme gives is a triage: before treating any dream as meaningful, ask what the body was doing. Most of the traffic, on this scheme's own ordering, is digestion and temperature. The supernatural category is placed last and marked rare — which is a more conservative position than the framework needed to take.
The useful thing here is a sorting question, and you can run it on your own material tonight. When something arrives — an intuition, a conviction about a person, a line, a sense that something is about to happen — ask: did any of the first five consciousnesses supply this? Did you see, hear, or notice something that generated it?
If yes, it's inference, and it can be checked by finding what you noticed. If genuinely not — if it arrived free of any input you can trace — then on this scheme it came from the image-faculty, and the scheme's own verdict on that faculty is rely on clear wisdom and analysis instead.1 Not because it's always wrong. Because there's nothing in it that corrects it.
Then watch the conditions. The account says this faculty takes over when clear discrimination stands down — sleep, exhaustion, fever, trance, absorption. So the practical rule is uncomfortable and simple: the more depleted you are, the more of your mental content is coming from the uncorrected half. Which is exactly when it feels most significant.
And for anyone doing creative work: the line that arrives and the conviction that arrives come out of the same faculty. You want the faculty running. You just don't want it running your judgements about the world — and it won't tell you which of the two it is currently doing.
One passage reaches outside the tradition for confirmation, and it's the only place in this material that does. Isn't it interesting that modern science has recognized the du-yin as a state of "psychological inadequacy"? — and then it reports that researchers hold telepathy to be most prevalent or effective when the normally clear conscious mind is groggy with sleep, befogged by hypnosis, trance, fever, or physical exhaustion. This is essentially the du-yin that they're recognizing.2 As a claim, that would be a genuine convergence: two independent traditions locating the same operating conditions for the same faculty.
The entire citation is Art Bell and Brad Steiger's The Source.2 A paranormal trade book, co-authored by a late-night radio host, standing as the evidence for what modern science holds about telepathy research. This build already excludes that source on this exact subject, and the standing rule is that an excluded item resurfacing isn't re-added — the recurrence is the finding. So it doesn't enter this page as content, and what's recorded instead is that the doctrine's one attempt at external corroboration rests on it.
Two further things are worth saying, because the failure is more interesting than a bad footnote.
The convergence claim would be checkable. The parapsychology literature has genuinely run studies in reduced-sensory-input and altered-arousal conditions, and whether ostensible effects concentrate there's a question with an answer. Bodri could have cited that literature. He cited Art Bell.
And if it held, it would cut the other way. It's cited approvingly, but the faculty is said to perform best under sleepiness, hypnosis, fever and exhaustion — conditions of degraded cognition, which is why he has to quote the phrase psychological inadequacy in the first place. A capacity that is strongest exactly where clarity is weakest isn't well described as a window onto anything. It's well described as an image-generator freed from correction, which is what the rest of his own account says it is.
The corroboration reached for would have knocked out the interpretation it was reached for to support.
There's a practice built on this faculty, and Bodri gives it in enough detail to be assessed — including, unusually, its exclusion criteria. The Esoteric school training begins with simple tasks: trying to transform water to fire in their dreams. He identifies this with what's now called lucid dreaming, while marking the difference in aim — the purpose in dream yoga is not just to gain control of dreams but to cultivate a certain wakefulness and ultimately a glimpse into the ultimate mind essence.3
The progression then leaves sleep. Once transformation in dreams is under control, the practitioner while awake starts on the road of experientially realising that everything is like a dream.3 The dream work is a rehearsal; the waking application is the point.
Then the screening, and this is the part that deserves attention because almost nothing else in the book supplies contraindications.
The body must be in condition — specifically, he names the chi mai of the stomach and intestines.4
And the practitioner must not already be dreamy. Candidates should not be "dreamy," absentminded or "spacey" individuals to begin with, because this type of practice may even exacerbate their problem.4
That's a screening rule, and it's the right one. A practice that trains the image-faculty is contraindicated for people whose image-faculty is already dominant — which isn't the intuitive rule, since those are precisely the people who would be best at it and most drawn to it. The stated risk backs it up: go the wrong way in these practices and they can easily become mentally unbalanced and can even go crazy.3 Given his own filing of insanity and dreaming under one faculty, that warning is internally consistent rather than decorative.
The same discussion turns to shamanic practice, and the handling has to be stated rather than absorbed. Bodri's position is that shamans try to cultivate the du-yin and can therefore offer very little in terms of true knowledge because they choose to cultivate this state of uncontrolled imagery and unclear stupor; that romanticising shamans and studying their trance states is the latest craze; and that whatever shamans offer certainly isn't a high road of genuine spiritual attainment and is nothing high-stage that will help human culture.5
This page reports that as the source's position and doesn't adopt it. The structural claim inside it — that trance practices which suspend clear discrimination are operating on the image-faculty — is at least a claim, and it follows from his framework. The verdict attached to it doesn't follow from anything. No shamanic tradition is named, no practitioner is cited, no primary or ethnographic source is consulted, and no distinction is drawn between the many unrelated traditions the word covers. What's offered as an assessment of a body of knowledge is an application of a category.
This is an instance of a standing pattern in the source rather than a one-off: indigenous material is annexed as evidence or dismissed as inferior, and not engaged as a body of knowledge. The build records that pattern at six of seven instances, and it fails as a universal — one footnote elsewhere in the book points readers at two Mayan sources, one of them a comparative work by authors inside that tradition. The pattern is real at that strength and no stronger, and it's stated here at that strength.
The one adjacent quotation he supplies is from Jenny Wade and is doing different work — a methodological point about which parts of shamanic practice fit a particular transpersonal stage model.5 It's a scholarly source making a bounded claim, and it doesn't license the surrounding verdict.
Strongest support. The faculty is defined by a single structural property — operation independent of the first five consciousnesses — and everything else follows from it: dreaming, hypnagogic imagery, inspiration, and the reduced-input conditions under which all of them intensify.1 That's a genuinely economical piece of faculty psychology, whatever one makes of the psi extension.
The tension the source does not close. The du-yin has really great range including future events, and the same paragraph says don't put much faith in dreams and rely on clear wisdom instead.1 Enormous reach and low trust are asserted together with no account of when to credit it.
A second tension, and it is the page's centre. The claimed convergence with modern research would, if true, show the faculty performing best under degraded cognition — which supports the image-generator reading and not the window reading.2 He cites it as support.
A third, on sourcing. The one external corroboration offered rests entirely on Art Bell and Brad Steiger's The Source, an excluded source in this build.2 Recorded as a recurrence rather than re-added.
A fourth, and it is a handling note rather than a tension. The shaman material is a categorical dismissal with no named tradition, practitioner or source. Reported, flagged, not adopted; the standing pattern holds at six of seven and fails as a universal.5
And the standing scope limit. Footnote 518's disclaimer covers the ladder these states sit on — rest stops and verifications rather than requirements.6
Open questions. Does the reduced-input claim actually hold in the research literature, and would it support or undercut the du-yin interpretation? And the screening criterion — that this practice is contraindicated for already-dreamy people — is unusually specific for this book: is there a tradition-internal record of how it was applied, or of what happened when it wasn't?
Against Psychic Abilities as Occipital Chi Pressure, this page supplies the psychology to that page's physiology, and they were built to be read together. There, chi at the jade pillow produces the effect; here, the faculty it recruits is named and its properties given. The two accounts agree on the crucial point — that what's recruited is the uncorrected half of ordinary mind — and they agree on the accuracy signature that follows.
The convergence with Samādhi States Are Images of Emptiness runs deeper than the shared vocabulary of images. That page's demotion says a state is a construction because a mind produced it. Here is the specific mind-component that produces constructions with no sensory anchor at all — which makes the du-yin the most likely source of the states that page is demoting, and neither passage says so.
Read with Semblance Dharmas, a mechanism appears that neither page states alone. A semblance dharma is a state manufactured from a description. The faculty that manufactures images from stored material without sensory input is the du-yin. The counterfeit-producing organ is named in one chapter and the counterfeit is named in another, four hundred pages apart, and the connection is never made.
Against You Cannot Elect a Saint, the du-yin account and Lambertini's finding arrive at the same place from opposite ends. He concluded that extrasensory knowledge doesn't discriminate between saints, fools and brute beasts. Bodri's scheme explains why it couldn't: the faculty producing it is the one shared by the dreaming, the inspired and the incoherent.
A simulator that runs whenever the room goes quiet — The Default-Mode Simulator. That page describes the experience precisely: you sit down to work and within ninety seconds you are replaying Tuesday's argument or narrating a triumph to an imaginary audience — swept there rather than choosing it, carried by mini-movies, while the actual room goes dark. That is the du-yin's operating description in contemporary vocabulary, down to the trigger condition: it takes over as external demand drops. What the pairing gives that neither side gives alone is a scope claim neither would make alone. The default-mode account treats the simulator as a distraction to be noticed and stepped off. The du-yin account files the same faculty as the source of inspiration, instinct, dreaming, psychic impression and incoherence — one organ, several outputs, no internal marker distinguishing them. Put together: the faculty you step off to do focused work is the same one you step onto to do imaginative work, and it supplies no signal about which mode it is currently in — which is why the arriving line and the arriving conviction feel identical, and why the traditions that cultivate it deliberately all attach warnings about madness. It also explains the screening criterion: telling an already-dreamy person to train the simulator is telling someone who can't get off the train to spend more time on it.
One handshake. The obvious second — assembly from stored material producing a distinctive accuracy profile — is carried by the occipital page in this cluster and would be restatement here.
Sharpest implication. The scheme files inspiration, intuition, dreaming, psychic impression and incoherence as outputs of a single faculty defined by its freedom from sensory correction — which means the tradition's own psychology predicts that the experience of receiving something true and the experience of generating something unchecked will be indistinguishable from inside.
Generative questions.
