The illusory body has a second name, and the second name is an argument.
Where people go wrong is in forgetting that the illusory body is also called the "substitute empty body," which is to remind us that this body is also empty of true reality.2
Take the term apart. Substitute — it stands in for the physical body, which is the whole attraction. Empty — it's no more real than the thing it replaces. Body — and it's still one of those.
Somebody built that name deliberately. It contains the promise and the refutation of the promise in three words, presumably so that nobody using it could forget the second half.
It didn't work:
People usually become fascinated by the Tantric school and want to cultivate its methods just to attain this body. However, they forget all the while that it's simply replacing one form with another, and that no form is ultimately real. Conventionally speaking, the illusory body may seem like a big improvement over our physical body, but don't think that it's any more real.2
The arrival isn't a project. It's described as spontaneous, and with an image: this "will occur spontaneously because of all these other transformations," and it announces itself "in the manner of a fish which leaps out of the water."1
That image is worth flagging, because it's the same one that turns up inside the twelve-analogy commentary — it arises from the clear light of emptiness like a fish leaping out of clear water — where it appears in place of an item that was on the list and never explained. Its recurrence here, unprompted and in a different context, establishes the fish as a live image in this tradition rather than an artefact of one translation.
The precondition is stated in heap terms rather than technique terms: at this stage you've finally lessened the ties of the form and sensation heaps, such that the illusory body can manifest.1 Loosening, not building. What produces the body is the removal of something.
And the other half of the "new life" gets deflated too. It doesn't just mean an invisible body that can travel the universe at will — it also means your purified physical body, rejuvenated by the process.1 So a good deal of what sounds like a second body is, on this account, the first one working properly.
Then a passage unusual in this book for admitting defeat:
If all these factors become purified, then your spiritual emanations will be purified and there are all sorts of emanations you can have. Some of them I can only describe as emptiness themselves, and others we can (though improperly) refer to as rarified forms of light, or even folds in space. Sorry, but I have no better way to describe them.1
Sorry, but I have no better way to describe them. That's a straightforward admission of descriptive failure from an author otherwise generous with categories, and it corroborates from the other direction what the twelve-analogy list implies. The tradition assembled twelve borrowed images because nothing available was close enough — and here a modern expositor hits the same wall and says so, in one sentence, rather than reaching for a thirteenth image.
These are said to go far beyond the simple chi projection bodies that announce the birth of the immortal fetus, and there are so many substances involved that it's hard to count them.1
The levelling is the section's real payload.
Ordinary people tend to think the various Tantric teachings are rather unique and one-of-a-kind, not to be found elsewhere. However, when you examine the methods outlined by Tsong Khapa, as well as the traditional techniques of Body, Speech and Mind Isolation, you'll find that their effects are not that much different from those of other schools which describe the cultivation pathway through terms like jing, chi and shen attainments.2
Medieval alchemy has the same stages, visible in the old picture books. So the manifestation of an illusory chi body "should not be surprising at all, and should not be considered an event unique to this school."2 And the sharpest version: these body teachings even appear in the Zen school, but most people know so little of true Zen that they don't realise it.2
The cross-tradition anchor is 1 Corinthians 15, quoted at length — there are celestial bodies and terrestrial bodies, the glory of one is one and the glory of the other another, and "there is a natural body, and there is a spiritual body."1 Notice what that's being used for. Not to claim Paul knew about illusory bodies. It's used for the weaker and more defensible point that a two-body distinction isn't exotic, and that a Western scriptural tradition already carries one.
Then the reduction, applied to his own material as readily as to anyone else's: what all of it really comes down to, in Taoist vocabulary, is jing-chi-shen and emptiness attainments — which is to say cultivating emptiness, which is to say samādhi and prajñā.2 And the general rule that governs the whole class: all the various bodies you can cultivate, including the bardo bodies, should never be mistaken for the ultimate achievement, because form isn't the cultivation path.2
Then a terminological correction that's the best thing on the page.
People think that the world is empty, or non-existent, but that's not a totally correct way to say things. It's better that we say that it is "ungraspable" because it's always changing, it's ungraspable because it's always coming, always transforming.2
The elaboration runs: phenomena are existent dharma, but they're not real. And since they're like a dream, you can't say they're either existent or non-existent — things in one sense are as they are and in another sense aren't. Which is just another way of saying don't grasp them, and that your mind shouldn't dwell in form or appearances but should abide in the Middle Path. With the Diamond Sūtra as backstop: one who attains supreme enlightenment won't say that dharmas are annihilated.2
Empty invites a reader to try to make things disappear. Ungraspable doesn't. That's a word chosen for what it stops the reader doing rather than for accuracy — and the reason is stated: you'll just tire yourself out or cause all sorts of anxieties.2
The instruction that follows is the most directly usable thing here, and it arrives as a list of what not to do. You can't stop phenomena. You can't annihilate them into nothingness or make them disappear. You can't stop existence and you shouldn't try, either by dwelling and holding or by blocking.2 Then the list gets specific, and it's the specificity that makes it a technique rather than a sentiment: don't try to stop phenomena, don't try to stop anything within your body, don't stop your internal chi circulations — and don't even stop your thoughts. How could you stop them, since they belong to the realm of phenomena?2
That last one is aimed at nearly every beginner's idea of what meditation is. The named failure mode comes from the Third Zen Patriarch and it's four words: stopping creates even more agitation. Alongside it, the sharper version — "trying to get rid of existence is obscuring being; trying to follow emptiness is turning away from emptiness."2 So the effort itself is the error, and it produces the opposite of what it aims at, which is why the practitioner who tries hardest here gets furthest from it.
And the positive instruction is one sentence: you just let go of everything around you, and then you're naturally existing in the present moment without dwelling.2 Not stopping. Letting go of, which is a different operation — the first is applied to the phenomenon and the second to your grip.
The reason it works that way is given too, and it's the one piece of theory needed to make the instruction make sense. Because the true mind doesn't dwell, all phenomena arise. Their nature of arising is emptiness, and because the nature of arising is emptiness, we have all phenomena.2 So the arising isn't the problem to be solved. It's the evidence that the thing you're looking for is already working.
Somebody in this tradition did the responsible thing. Faced with a technique that reliably produces an attractive result, and a doctrine saying the result isn't the point, they built the caveat into the name.
It's elegant. The term can't be spoken without stating that the body is a stand-in and that it's unreal. Every use is a reminder. On paper that's the most robust place a warning could possibly live, because you can't skip the label the way you skip a preface.
And it's reported failing, in exactly the population it was built for: people become fascinated and want to cultivate the methods just to attain this body, "however, they forget all the while."2 The reason is a property of names rather than a failure of the practitioners. A compound term is parsed once and used thereafter. The first time you meet substitute empty body you read three words; the tenth time you read one label. That transition isn't carelessness — it's what makes a technical vocabulary usable at all, and a term you had to unpack on every use would be abandoned inside a year.
Which means the encoding has a defect its elegance conceals. The very property that lets a name carry a warning — compression — is the property that guarantees the warning stops being read.
Put that against what compressed language is normally praised for. A symbol is a shortcut, holding dozens of meanings in one phrase, and its power is delivering all of them without argument. Compression is an asset when you want people to feel something, because feeling doesn't require unpacking. It's a liability when you want them to check something, because checking does.
So the tradition put its caveat in the one container that would be handled constantly and opened never. Warnings need friction, and names are built to remove it.
Which predicts where else this fails, and the prediction is easy to test in any technical field. Best-effort delivery. Rough consensus. Non-binding guidance. Preliminary findings. Each was named by somebody trying to build a limit into the label, and each is now a unit whose qualifier has gone silent. The qualifier survives longest where the term is used least — and the terms we most need qualified are the ones we use most.
The remedy is visible on this page and it isn't elegant at all. The warning gets reissued in prose, at length, by a person, in every generation — a paragraph spent saying what the name already says, because the name has stopped saying it. That isn't redundancy. It's the maintenance a compressed warning requires, and a tradition that stops doing it won't notice the loss for a long time, because the term is still there.
You won't attain an illusory body, and the page still has a use, and it's the name. Take the thing your practice is currently aimed at — the settled mind, the open channel, the state you'd like back. Now name it the way this tradition named that: a term holding what you want and the reason it won't satisfy you, in the same breath. Substitute empty calm. Substitute empty clarity.
It feels absurd, and that's the measurement. The absurdity tells you how much of your attention the first half is holding.
Then the honest observation about why the trick fails anyway. You'll use that term a hundred times and parse it never, because names become units the moment they become useful. So don't rely on it. Say the whole sentence out loud once a month instead — this state is a stand-in and it isn't more real than what it stands in for — because a sentence has friction and a label doesn't.
The instruction that actually transfers is the one about stopping, and it's testable this evening. Sit, and notice how much of what you're doing is stopping — stopping thoughts, stopping restlessness, stopping the itch, stopping the noise from next door. Every one of those is on the list of things you can't stop. Then try the other operation: let go of your grip on them instead, and leave them running. If the Third Zen Patriarch is right, the second is quieter than the first within ten minutes, and the difference is measurable in how tired you're at the end.
And carry the general rule off the page, because it's the part that applies to every state you'll ever reach: whatever your practice produces will feel like an improvement on your ordinary condition, and feeling like an improvement isn't the same as being a different kind of thing. It's the same kind of thing, better arranged.

The ungraspable-over-empty correction is the best teaching here, and the reason is given plainly — empty invites an attempt at annihilation that produces only fatigue and anxiety.2 The stopping instruction is specific enough to act on and carries a named failure mode.2 The levelling claim has a testable form.2 And sorry, but I have no better way to describe them is an honest admission of limit in a book that rarely offers one.1
The tension the source doesn't close: the name was built to prevent exactly the fascination it reports, and it failed. Nothing addresses why, or what would work instead — the remedy on offer is a paragraph of prose restating the name, which is presumably what every previous generation also did. A second: whether the "new life" is a second body or the first one rejuvenated gets answered both ways within a page.1
🚩 A substantial historical claim is made with no school named and no source — that after Shakyamuni's death "a particular school of Buddhism arose that focused on the appearance side of the Tao."2 Recorded as a further instance of the logged unnamed-targets pattern. 🚩 SECONDARY WITHOUT PRIMARY on the Eckhart material in this stretch, via Forman's Mysticism, Mind, Consciousness, SUNY 1999, p 147 — a further instance of the recorded Forman dependency [n≥3].1 The Pauline passage is quoted with chapter and verse and no edition.
Scope limit: this is a Completion Stage attainment beside a ladder the source's own footnote 518 calls conventional,3 and its own summary agrees — it all comes down to jing-chi-shen and emptiness attainments.2 Open question. If a warning built into a name reliably goes silent, has any tradition anywhere found a container that holds one — or is periodic reissue by a living teacher the only mechanism that has ever worked?
Two things this material does at once, and a reader coming to it fresh will take away whichever they were already inclined to. It describes the attainment in detail — the fish leaping, the emanations of light and folds in space, the purified body, the substances too numerous to count — with evident interest and at length. And it says, in the same pages, that the whole class should never be mistaken for the achievement, that form isn't the path, and that a name was built to stop exactly the fascination the description produces.
The two aren't reconciled and they can't easily be, because the description is what makes the warning necessary. Anyone who writes attractively about an attractive result has created the appetite the caveat then has to manage — and the caveat, on this page's own evidence, doesn't manage it. What the material has instead of a resolution is repetition: the warning restated in prose every time the description gets vivid, which is a maintenance schedule rather than a solution and is presented as though it were one.
Behavioral mechanics — The Symbol as Shortcut. That page treats a symbol as a compression device: a shortcut of expression holding dozens of meanings in one phrase or object, whose power is that it delivers all of them at once and without argument. That's exactly why symbols work on people — they arrive whole, they don't require unpacking, and the recipient feels the meaning before they could have examined it. Now set that against what this tradition tried to do with substitute empty body, which is to use compression to carry a caution. The pairing exposes why it had to fail, and the failure is structural rather than cultural. Compression is an asset when you want somebody to feel something and a liability when you want them to check something, because feeling doesn't require unpacking and checking is nothing but unpacking. A warning that arrives whole and unexamined isn't a warning; it's a mood. So the tradition put its safeguard in the one container guaranteed to be handled constantly and opened never, and the elegance of the design is precisely what disabled it. Which gives a rule with reach well past either page: never encode a limit in a name you expect to become common. The qualifier survives longest where the term is used least, and the terms that most need qualifying are the ones used most, so the decay is fastest exactly where the stakes are highest. And it explains why every tradition that carries a dangerous attainment ends up with a living teacher restating the caution in prose — not because the prose is better, but because prose has the friction that a name is engineered to remove.
Sharpest implication. A warning built into a name is the most elegant and least durable place to put one. Compression is what lets a term carry a caution and it's also what guarantees the caution stops being read, because a compound is parsed once and used forever after. Which means the only mechanism that has ever kept a dangerous teaching safe is somebody saying it out loud again, in full sentences, to each new generation — and that's a maintenance cost, not a design.
Generative questions.
