At the third rung you gave up joy and kept bliss. At the fourth, the bliss goes too.
What's left, in Buddhism's accounting, is one-pointedness and "profound equanimity" — "an equanimous state of neither pleasure nor pain that we should consider real bliss."1 Not a better feeling. The end of feeling being the thing at issue. And the equanimity itself isn't just inherited from the rung below: the mental equanimity of the third dhyāna "has become even more refined and purified" here.42 Two things are happening at once, then. Bliss subtracts, and what remains gets finer.
The operation that gets you here is different in kind from the three below it. Those removed particular contents — coarse aiming, refined attention, joy, bliss. This one removes the machinery. "The fourth dhyāna represents a total abandonment of false thought, so it's a stage wherein we can say you're finally liberated from thought."2
The traditional name says it: "The Pure Ground of Renouncing Thought," so called for its extremely high degree of mental purity compared with the three rungs below.3 Not renouncing thoughts. Renouncing the production of them.
The technical gloss in the eight-consciousness scheme: this rung "can finally be considered a realm of no-thought whereby you've really settled the sixth consciousness and made great inroads into purifying the conception skandha."4 Great inroads — not completion. The hedge is in the original and it matters later.
There's a status change here that happens nowhere else on the ladder, and it arrives in one sentence:
"But this state of the fourth dhyāna is so excellent that it's finally called a stage of liberation. It's a stage unlike the first three dhyāna because they still haven't escaped from the distraction of physical sensations and feelings, which you finally accomplish in the fourth dhyāna."5
Look at what that reclassifies. The first three rungs — including the one that supposedly ends all remaining disease in the body — get grouped together as not liberated, on the single ground that physical sensation is still a distraction in all of them.6 The third dhyāna's sublime bliss, the "bliss of the sages," is on the wrong side of that line. So is the second's stopped breath and the third's stopped heart.
The Buddha's own description follows, and the striking thing is that the body hasn't disappeared:
"is beyond pleasure and suffering and possesses the purity of attention due to equanimity. He [the practitioner] sits down and penetrates this very body with a pure and lucid spirit, so that not a single part of his body remains unaffected. To one who lives in this way, devoted, alert and determined, the memories and the ways of the world vanish. Then his spirit will strengthen internally, will be calm, harmonious and concentrated. In this way, O Monks, you cultivate the attention of the body [which is the means of practice to reach this state]."7
The body is still there and still being pervaded. What's gone is the pull — sensation no longer competing for attention. That's a much more precise claim than transcendence-of-the-body, and it's the one the text actually makes.
And the last sentence is the technique, sitting in plain sight at the end of a passage usually quoted for its first line. Attention of the body is the means of practice to reach this state. Not withdrawal from the body. Penetrating it with a pure and lucid spirit until no part is unaffected. The method and the marker are the same operation seen from two ends.
The same rung gets four descriptions, and each names something the others leave out. Buddhism gives the mental factors: equanimity and one-pointedness, thought-production ended, the conception skandha substantially purified.4
Taoism describes it as a state of great emptiness, produced by the absence of thoughts — and puts it on the map by proximity: "it's very much near the stage where shen completely transforms into emptiness."40 That's a location in the jing-chi-shen sequence rather than a description of an experience, and it's what the Taoist column is for. Near, not at. The transformation of shen into emptiness is still ahead.
Tantra makes a point of the bliss specifically. It's "so extremely subtle that it seems non-existent," which is why the rung gets characterised by an innate bliss where "emptiness and bliss have joined into one."41 Read against the Buddhist column that's a disagreement about description rather than about state. Buddhism says bliss has gone. Tantra says bliss has become so fine it's indistinguishable from emptiness. Same rung, and a practitioner would report either depending on the vocabulary they were handed.
Yoga, through Vyāsa, gives the cleanest sequence of the four, because it's the only one that states the whole ladder as a single subtraction:
The vitarka-conjoint samādhi actually accompanies all four. The second one, with gross thought (vitarka) having been terminated, is accompanied by subtle thought (vicāra). The third one, with subtle thought having been terminated, is accompanied by bliss (ānanda). The fourth one, with that bliss having been terminated, is merely I-am-ness (asmitā). All these samādhis are dependent on, conjoint with, or accompanied by supportive factors.43
Each rung is named by what accompanies it after the previous accompaniment is cut. Gross thought, subtle thought, bliss, I-am-ness. And every one of the four is a support — which is the distinction the next section turns on.
Then comes a reversal the rest of the ladder doesn't prepare you for.
"In summary, the fourth dhyāna is a very profound state of cultivation attainment, but it's still within the Realm of Form. It reaches to the heavens at the very top of the Form Realm, but it is still considered a Form Realm attainment that is an image of emptiness, rather than an experience of true emptiness itself. Nevertheless it's on the very border of making this statement untrue."8
That last sentence is the most carefully weighed thing in the chapter and it's worth reading twice. The rung is an image of emptiness. It's also so close to the real thing that saying so is nearly wrong.
The yoga column supplies the technical reason and it's clean. All four of these absorptions "are dependent on, conjoint with, or accompanied by supportive factors."9 The gloss: "In yogic terminology, all these samādhi are 'accompanied by supportive factors' and that's why they are Form Realm concentrations rather than Formless Realm samādhi attainments."10 The formless states above are defined by the negative — they "have no form-based supports as do the various first four dhyāna."45
So the whole ladder, all four rungs including the one called liberation, is defined by leaning on something. The formless absorptions aren't more refined versions of the same thing. They're the first states with nothing underneath.
And Vyāsa's name for what's left at the fourth rung is exact: asmitā, "merely I-am-ness."11 Every content has gone. What hasn't gone is the bare fact of there being someone this is happening to. That's the support.
The strongest evidence for the ladder arrives as a throwaway. "Don't think that only the Tao school recognizes this categorization scheme, for even the Zen school recognizes these phenomena! This is something that modern scholars all tend to ignore."12 Then Yun-men:
In the first stage of meditation, thoughts stop. In the second stage of meditation, breathing stops. In the third stage of meditation, the pulses stop. In the fourth stage of meditation, extinction culminates in great stability.13
Four rungs, physical markers, same order as the Taoist column — from a Zen master, in a tradition with a reputation for having no use for staged attainment schemes at all.
The Grass Mountain Ch'an synopsis runs the same sequence and then adds something the others don't:
The fourth dhyāna is dropping thought [altogether] to reach purity. "The two forms, movement and stillness, spontaneously do not arise." What is spontaneously not arising? It is I. Spontaneity is selfless.14
That line deserves its own hearing, because it names precisely what makes this the last rung on its side of the border. Movement and stillness both stop arising. Then the question: what is it that isn't arising? It is I. And spontaneity is selfless.15
The cross-tradition identification is made explicit — "Even in Taoism we have this description of no-thought and no-self appearing, which is the equivalent of the I-am-ness of Hinduism or the 'extinction' and 'emptiness' of Buddhism."16 There's a real problem sitting in the middle of that sentence and it goes straight past. Asmitā is I-am-ness, a residue, the thing that's left. The Ch'an line says selflessness, an absence. They're treated as equivalents, and in form they're opposites — one names what remains at the fourth rung, the other names what's gone.
They are reconcilable, and the reconciliation is probably right. What remains is bare being-there with no self-content in it, which from one direction reads as the last residue and from the other as the first selflessness. But the reconciliation has to be made, and it isn't. The equivalence is asserted. Recorded as a tension rather than resolved.
Then the closing move, which is the reason this rung exists at all: "This stage of non-ego is what enables you to see the Tao when you can drop even the fourth dhyāna."17 The ladder's payoff isn't the top of the ladder. It's being in a position to let go of the top of the ladder.
One more thing about the two Chinese sources. They're Chinese Buddhist and they're reporting the Taoist column — the physical one — rather than the Buddhist mental-factor column. That's either a school reading its host culture's instrumentation, or two independent traditions finding the same physical sequence, and nothing in the text settles which. [n=2 SUGGESTIVE]. But a Zen source giving a four-stage physiological ladder cuts against the standard picture of Zen as the school that refused ladders, which makes it inconvenient for the received view whichever way it resolves.
For a first-person progression through all four rungs, the chapter turns to the Ekottara-Āgama account of Rāhula, the Buddha's son — via Nan Huai-Chin's Working Toward Enlightenment.18 Chain: B citing Nan's rendering of the sutra, not the sutra directly.
The account tracks the subtraction sequence exactly, with inline glosses. First dhyāna — "had awareness and contemplation, and he was mindful of joy and contemplation." Gloss: still in the realm of vitarka, vicāra, and the sixth consciousness. Second — "without awareness, without contemplation, mindful of the joy of samādhi." Gloss: vicāra without vitarka. Third — "no longer mindful of joy. He held to his awareness and bodily bliss, the joy which is always sought and preserved by all the worthy sages." Fourth — "both suffering and pleasure were extinguished, and he had no more sorrows or worries, no more suffering or pleasure. Preserving a state of pure mindfulness."19
What makes this worth a section is what comes after the fourth rung in the same passage, because that's where the ladder stops being the point. His mind becomes "pure and clean, and free from the defilements of sense objects," then free of all bonds, then stainless. Then "he attained liberation from the mind of desire and defilement," then liberated wisdom — glossed as he saw the Tao. And then: "Birth and death were ended."20
The four dhyānas occupy four sentences. The thing they were for occupies the rest.
And the Buddha's response to the report isn't congratulation on the absorptions at all. It's: "You fully abide by the precepts of discipline, and you have perfected all your faculties. Gradually you will reach the stage where all bonds and the impelling forces [of karma] are ended."21 Gradually you will reach. The most complete first-person account of the four dhyānas in the chapter ends with the teacher pointing further up.
One thing this passage does that the surrounding chapter doesn't: it names the technique. Rāhula asked for a method, was given ānāpāna — breath mindfulness — went into the forest, and worked it.22 No initiation, no lineage, no transmission event. A question, an instruction, and time.
Years in. The sits have gone quiet in a way you no longer mistake for dullness. Then one day the bliss isn't there either. Not suppressed — just absent, the way a sound you'd stopped noticing is absent once it stops.
1. Don't read the loss of bliss as loss. There's no reassurance available here. The equanimity that replaces bliss doesn't announce itself and doesn't feel like a reward. The marker isn't a feeling at all. It's whether thought is being produced — not whether thoughts are occurring, but whether the machine that makes them is running.25
2. Check for alertness, because torpor imitates this rung. In the imitation, thoughts have stopped because attention collapsed; poke it and it wakes up cross. At this rung the state is one of pure mindfulness and lucidity, and the Buddha's phrase is "devoted, alert and determined."26 Alert is the operative word. If the quiet is drowsy, it's torpor with a good reputation.
3. Work the body, and work it into rather than away from. The stated means of practice is cultivating the attention of the body — penetrating this very body with a pure and lucid spirit until not a single part remains unaffected.44 That's the instruction, and it's the opposite of the withdrawal people assume. The distraction of sensation ends by saturating the body with attention, not by leaving it.
4. Expect the bliss report to depend on your vocabulary. If you were trained in the tantric frame you'll describe an innate bliss so subtle it's indistinguishable from emptiness. In the Buddhist frame you'll say bliss has ended.41 Both are descriptions of the same rung. Don't conclude you're in the wrong state because your words don't match your lineage's.
5. Then the instruction the whole ladder was built to make possible. You're at the top of the Form Realm. This state is an image of emptiness rather than emptiness, and the way forward is to drop even this.27 After years of work, at the most refined state you've ever reached, the instruction is to let go of it. The reason isn't that it's bad. It's that it's still leaning on something, and the thing it leans on is the bare sense that this is happening to you.28
Nobody arrives here by accident and stays. The rung isn't a destination. It's the only place from which the last letting-go is available.
A historical claim is attached to the ladder that's easy to skip and is doing real argumentative work.
When Buddhism first entered China in the Eastern Han, the account runs, "it was only accepted into this new culture because it emphasized the work of actual cultivation practice, and this work produced results that no one could deny." People read the techniques — the skeleton visualisation, breath mindfulness — practised them, and attained the dhyānas.23
The frame put on it: "That's the way cultivation science works — it's exactly like physics or chemistry in that there are theoretical principles, and so you practice according to the theory and then get results which prove their verity." And so "the established powers in China at the time could do nothing but accede to Buddhism's authenticity."24
Take the reproducibility argument seriously and it's the best structural case in the chapter. A foreign religion arriving with no political sponsor, no army and no existing constituency has one thing to sell: a procedure that works when strangers run it. If the dhyānas were doctrine, the transmission would have needed a patron. If they were a repeatable result, it wouldn't.
Take the historical claim seriously and it's thinner than the frame it carries. No source is offered and no case is made for the Han reception story, and the actual history of Buddhism's Chinese entry involves translation programmes, court patronage, trade routes and Daoist vocabulary borrowing — none of which appears. [PLAUSIBLE — needs corroboration] as a partial factor; [CONTESTED] as the sole mechanism.
The argument that survives isn't the historical one. It's the criterion embedded in it: a practice tradition that can't be independently reproduced by someone outside it has nothing to offer a culture that doesn't already believe it. That criterion is worth more than the anecdote it arrived in.
[POPULAR SOURCE] throughout, and three chains to keep straight: the Buddha quote is via Odier's Nirvana Tao, Vyāsa via Arya, Yun-men via Cleary.7913
Strongest evidence. Yun-men's four-stage physiological sequence.29 A Zen source, quoted by a translator with no stake in the Taoist column, reporting the same four markers in the same order. It's the one piece of the concordance that comes from a tradition with a doctrinal reason not to produce staged attainment maps.
The unresolved tension. Asmitā is I-am-ness, what remains. The Ch'an line says spontaneity is selfless, what has gone. They're called equivalent without argument.30 The reconciliation is available and isn't made, and the two formulations point opposite ways.
A second tension, on the liberation status. The fourth dhyāna is "a stage of liberation"31 and, on the same page, an "image of emptiness, rather than an experience of true emptiness itself."32 Both hold only if liberation here means liberation from sensation specifically rather than liberation as such — consistent with what the rung is said to accomplish, but the word is left doing double duty and a reader could easily take the stronger sense.
A third, on the bliss. Buddhism's column says bliss has gone. Tantra's says bliss has become so subtle it seems non-existent and has merged with emptiness.41 Those aren't the same report, and no reconciliation is offered.
Open questions. Yun-men and the Grass Mountain synopsis are Chinese Buddhist sources reporting a Taoist-style physical sequence. Independent convergence, or a school describing itself in its host culture's terms? Nothing in the text distinguishes them. And the Han reception claim does structural work with no historical support attached — what would actual evidence for reproducibility-driven adoption look like?

(Read as tensions within the subject.)
Two criteria for what counts as a genuine absorption are in play, and they'd sort a practitioner's experience differently. On the strict one, vivid bodily phenomena disqualify the state — "if you can feel these various things that Ramakrishna described while you're 'in dhyāna,' then you aren't truly in dhyāna," because the absorptions are entered by detaching from sensation.34 On the looser one running through the Taoist column, the physical markers are the evidence: breath stops at the second rung, pulse at the third. A practitioner with a stopped pulse is either well advanced or disqualified, depending on which criterion is being applied, and both criteria sit in the same chapter.
The same knife is used on both sides of the aisle, which is what keeps it from being sectarian. Ramakrishna's five samādhis — ant, fish, monkey, bird, serpent, sorted by the movement of the spiritual current — are demoted to "descriptions of the phenomena that appear at the cultivation stage of clearing the chi channels."33 Form and sensation skandha phenomena. Preliminary. Then Buddhism's own five kinds of meditative bliss — minor, momentary, showering, uplifting, pervading — get exactly the same treatment: "these descriptions of bliss sound very beautiful and poetic, just as do Ramakrishna's explanations, but they certainly aren't states of samādhi." The most granted is that "pervading bliss" approaches the first dhyāna's.35 A canonical Buddhist taxonomy, demoted with the same argument in the same breath.
One inference goes further than the material supports. Ramakrishna's cancer is cited as showing the physical body wasn't fully purified and the channels not fully open.36 That runs the framework backwards — from an outcome to a verdict on someone's attainment — and treats an illness as diagnostic of spiritual rank. Nothing supports it beyond the framework asserting it, and it would be unfalsifiable in either direction. [LOW CONFIDENCE], recorded, not carried.
Set against The Second and Third Dhyāna, where the same discrimination is applied to Swami Rama's stopped heart: the criterion is stable across cases and applied to Buddhist material as readily as to Hindu. That consistency is what earns it whatever authority it has.
Ego Death State works the territory where the self-structure dissolves, and the clinical literature's recurring finding is that these states aren't uniform. They range from terrifying annihilation to serene dissolution, and what predicts which one you get is largely what was left standing when the structure went.
Asmitā is the precise contribution the dhyāna scheme makes to that question. Vyāsa's fourth-rung entry is "merely I-am-ness" — every content stripped, the bare fact of being someone still present.37 And this ladder says that isn't a failure to go far enough. It's the correct terminal state of the Form Realm, and it's what makes the next step possible: "this stage of non-ego is what enables you to see the Tao when you can drop even the fourth dhyāna."38
The insight the pairing produces runs against both sides' instincts. The clinical frame treats residual self-sense during dissolution as incomplete letting-go — the part that resisted. The contemplative frame here treats it as the platform: you can't drop the last support until you're standing on nothing else. So the two traditions are describing the same residue and disagreeing about whether it's debris or a foothold.
And that disagreement is testable in the one place it matters. On the clinical reading, a stronger residual I-am-ness predicts a worse outcome — more resistance, more terror. On this reading, arriving at bare asmitā with nothing else attached is the best possible position, and the states that go badly are entered from lower down with contents still in play. The ladder predicts that the sequence matters more than the depth. Nothing in either literature has tested that, and you can't even ask the question without holding both frames at once.
Technology Adoption and Rejection is about why societies take up or refuse an available technique, and its recurring finding is that demonstrated efficacy is rarely sufficient and often not necessary. Adoption tracks social fit, patron interest, and who loses status if the thing works.
The Han China story is the pure efficacy model with everything else stripped out: Buddhism was accepted because you could experientially prove everything it had to say, and the established powers "could do nothing but accede."39
Held against the adoption literature, that's almost certainly wrong as history and interesting as a claim about what kind of thing the dhyānas are. Notice what the efficacy model requires. The technique must work for people with no prior commitment to the framework, produce a result they can recognise without being told what to look for, and do it reliably enough that refusing to believe becomes the harder position. Very few religious claims can meet that. This one is being asserted to — and the four-column concordance is exactly the evidence that assertion would need, since agreement across traditions sharing no vocabulary is what independent reproduction looks like from outside.
So the handshake produces a reframing rather than a correction. The Han anecdote is weak history doing the work of a strong methodological commitment: treat a contemplative claim as adoptable technology, and the whole evidentiary standard changes — from what the tradition testifies to what a stranger can reproduce. The commitment is never stated. The chapter is built on it, and the adoption frame is what makes it visible.
Sharpest implication. The top of a ladder is defined by what it still leans on, not by how high it is. This rung has removed every content — coarse thought, refined thought, joy, bliss, the pull of sensation — and it's still a Form Realm state, because someone is there. That single residue keeps it inside the world it was climbing out of. The last thing to go is never a content. It's the fact of there being somewhere for contents to appear. Which is why the ladder's final instruction is to drop the ladder, and why that instruction can't be given early.
Generative questions.
