Anyone who has learned a physical skill knows this sequence, even if nobody named it for them. First something starts to work. Not reliably, not on demand, but occasionally the thing happens and you can feel that it happened. Warming.
Then it gets good. You've a best day, and on that day you can do it. You can't repeat it tomorrow. The peak.
Then comes the long ugly stretch where the peak won't come back and you keep going anyway. Nothing improves for months. This is where most people quit, and the name for the stage is exactly right: patience, or forbearance.
And then a plateau that is genuinely high — the best you can do while still doing it the way you've been doing it. Highest worldly attainment. The ceiling of the ordinary approach.
Buddhism uses these four to partition the second stage of the path, the stage of intensified preparatory practice. The Sanskrit collective term is the nirvedha-bhāgīya, the portions conducive to penetration. They're laid out at page sixteen and returns to them for eight pages afterwards.1
This page exists partly to correct a record, and the correction matters more than it might appear. The vault already held these four, at second hand, through an intermediary corpus, where they were labelled "his four stages." Both pages carrying them hedged the attribution and flagged that it rested on a targeted reading of a secondary document.
The primary text settles it. He presents them as Buddhism's own partition of the preparatory stage — "Buddhism does exactly this, and partitions the Stage of Intensified Practices into a sequence of four phases" — and then matches them to the Haṭha Yoga Pradīpikā's four-fold scheme of ārambha, ghaṭa, paricaya and niṣpatti, calling that "almost an exact matching of teachings."1
So the hedging pointed at the wrong risk. The danger was never that the attribution was too weak. It was that calling them his over-credits the transmitter, who is a conduit here, and says so.
That's a small correction with a large moral, and it's treated at Identical Metaphor, Different Attainment: what dropped out of the chain of transmission wasn't a citation. It was a doctrinal-tradition marker — a Buddhist scheme of the path of preparation, arriving somewhere else in devotional clothing, with nothing in the vocabulary to signal that it had moved.
The four are more interesting than a stage-list because they're said not to apply once. They apply to every gong-fu. To every absorption, individually. So a practitioner working on the second dhyāna goes through warming, peak, patience and highest-ordinary inside that one attainment, and then does it again in the third.
And then the claim that makes the page worth building: they apply to learning to cook, to ice-skate, to ride a bike.2 That's the cross-domain connection drawn in the text itself, which is rarer and more valuable than a vault-imposed one. The scheme isn't a description of spiritual progress that happens to resemble skill acquisition. On his account it is skill acquisition, running at every scale, and the contemplative case is one instance rather than the parent.
If that's right, then the four aren't a doctrine to accept but a shape to check — and everyone reading has already lived through it several times, in domains where the evidence is public.
The fourth name repays a second look, because it's doing something the other three aren't. The first three describe how the practitioner feels. The fourth describes a limit. Laukikāgradharma — the highest of worldly dharmas — is the best result available inside the ordinary frame, and the point of naming it is that going further isn't a matter of doing more of the same.
That's why the whole four-part sequence sits inside the preparatory stage rather than spanning the path. You can execute all four perfectly and be exactly where the stage-scheme says: prepared. The plateau at the top of them is not a failure of effort. It's what completed effort looks like from inside, and the thing that follows it is a different kind of event.
This is the structural point most likely to be lost when the four get borrowed, because a four-stage sequence naturally reads as a path, and readers supply a fifth stage where the tradition supplies a discontinuity.
You've been working at something for two years and it has gone flat. You had a period early on where it started working. You had a stretch, maybe six months in, where you were noticeably good — and you haven't been that good since. Now it's grinding and you're wondering whether you have the aptitude, or whether this was the wrong thing to spend two years on.
Locate yourself before deciding anything.
Ask whether the peak actually happened. Not whether it was sustained — whether there was a period, however short, when the thing worked. If yes, the capacity is established and the current flatness isn't evidence against it. If no, you may genuinely still be in warming, and warming can take much longer than anyone tells you.
Then ask how long the flat stretch has run. This is the stage the scheme names patience, and naming it is most of the help. The flatness isn't a sign that something has gone wrong. It's the stage, and it's the one that eliminates people — not because they lack the capacity but because nothing in the experience distinguishes "grinding through the necessary stretch" from "wasting my time."
Then check what you are still doing the same. If you've been flat for a long time and everything about the approach is unchanged, you may be at the fourth stage rather than the third — the ceiling of the current method. Those two feel identical from inside and need opposite responses: patience means keep going, ceiling means change something structural.
And expect to run the sequence again. The recursive claim is the practically useful part. The next capacity you build will have its own warming, its own peak, its own long flat stretch. Knowing that in advance doesn't make the flat stretch shorter. It stops you reading it as a verdict.
The strongest thing done with these four isn't the exposition — it's the cross-check, and it's worth examining because it's one of the few correspondences in the book that survives his own criterion. He sets the Buddhist four beside the Haṭha Yoga Pradīpikā's: ārambha (the beginning, when the practice starts to take), ghaṭa (the vessel, when things consolidate), paricaya (accumulation, the long gathering), niṣpatti (completion, the final ordinary perfection).
Two things make this a better match than most of the book's correspondences. The schemes are structurally parallel rather than lexically similar. He isn't matching a word for warmth to a word for warmth. He is matching four positions in two four-part sequences that both describe the same stretch of the same kind of work — the consolidation phase before something else has to happen. The names don't resemble each other at all, which is a point in favour rather than against.
And the fourth terms agree about the limit. Niṣpatti means completion, and in the yogic scheme it is the perfection of the preparatory work, not of the path. Laukikāgradharma is the highest of worldly dharmas. Both traditions independently place a named ceiling at the end of four stages, and both treat what comes after as discontinuous.
That's agreement on a structural feature rather than on imagery, and it's the kind of match Buddhism as a Comparative Reference Grid argues is the only reliable sort. Whether the two traditions are describing the same terrain remains unproven. But they're at least making the same shape of claim, and the shape is checkable.
The collective name is the most informative thing about the set, and it never gets used — the nirvedha-bhāgīya, the portions conducive to penetration. That framing tells you what the four are for. They aren't four qualities to develop, and not four experiences to have. They're the segments of a run-up. Each is named for what's happening to the practitioner's relationship with the material rather than for a state achieved: heat is friction beginning, a peak is the highest point of a curve, patience is what's required when the curve flattens, and the fourth is the top of the ordinary range.
Read that way the sequence isn't arbitrary, and you can see why it resists being extended. Add a fifth and you would have to name something between "the best the ordinary approach produces" and the discontinuity — and there's nothing there. Remove one and the account loses either the early flicker or the flat stretch, which are the two segments practitioners most need named, for opposite reasons: the first because it's easy to over-read, the second because it's easy to quit inside.
The scheme's most important feature is the thing it doesn't describe, and it's worth stating because a reader will otherwise supply it. After the fourth stage there's no fifth stage of the same kind. The four are the whole of the preparatory sequence, and what follows them isn't more of it.
That's why the tradition treats the transition as a break rather than a step — and why the larger frame puts Seeing the Tao in a different category from the stage that precedes it rather than at the top of the same ladder. The four take you to the edge of what refining an approach can produce. They don't, on this account, produce the thing on the other side, and nothing about executing them well makes the crossing more likely except by removing obstructions to it.
This is the part most easily lost in transmission. A four-part sequence has a strong natural reading as a path to somewhere, and every borrowing of these four that this build has traced reads them that way. The tradition's own reading is narrower and stranger: a run-up whose completion isn't an arrival.
Strongest support. The four are attested here with those glosses, presented as Buddhism's own partition rather than his invention, and cross-checked against a named yogic scheme with a parallel structure. The recursive extension to ordinary skills is the source's own, which removes the usual worry that the vault has imposed a secular reading.
The tension the source does not close. If the four apply to learning to cycle as well as to the second dhyāna, then either the contemplative case is not special, or the four are so general that locating yourself among them tells you very little. Both are wanted here — a universal shape and a specific diagnostic — and doesn't say how a scheme that fits everything constrains anything.
A second tension, inherited. These sit inside the preparatory stage, which is the stage the book relocates nearly all world practice into. So the four are simultaneously the most portable thing in the book and a description of the part of the path almost nobody is said to get past. Both are true and they read very differently depending on which you meet first.
And the standing status line. The stage-scheme these four sit inside is disclaimed by its own author — see False Stages, and the Footnote That Says So. The four are offered as a rest stop and a morale aid, not as a measurement.
Open questions. Does the yogic four-fold scheme mark the same discontinuity after niṣpatti that the Buddhist one marks after highest-worldly-attainment — or is the parallel only in the first three? And if the sequence recurs at every scale, what determines the grain at which you should be locating yourself?
The direct correction runs to The Bhūmi-Kāṇḍa Correspondence System, which carries these four at second hand under the wrong attribution. That page's hedge should be replaced rather than removed: the content it reported was accurate, and the framing over-credited the transmitter. The deeper finding is that a Buddhist preparatory scheme travelled into a devotional corpus and arrived re-badged, which is a case study in exactly the transmission failure the source itself describes.
Against Dhāraṇā, Dhyāna, Samādhi, Saṃyama, the relationship is one of scale rather than rivalry. Patañjali's sequence describes the deepening of concentration; the four prayoga stages describe the consolidation of any practice, including that one. On the recursive claim they should nest — each of Patañjali's stages having its own warming, peak, patience and ceiling — and that's a specific prediction the vault could check against the Yoga Sūtras directly.
The stage that eliminates people — Ego Development Theory Hub. The third term is the one worth taking outside the tradition. Patience names the long unrewarding stretch after early progress stops and before consolidation shows, and its defining property is that nothing inside the experience distinguishes it from failure. The developmental literature has the same problem under other names — plateau, arrest, the long middle — and the same practical difficulty: the person in it can't tell, from inside, whether persistence is warranted. The insight the pairing produces: the flat stretch isn't a signal that can be read, and treating it as one is the error — which means the decision to continue has to be made on grounds other than how the work currently feels, and any framework that promises to tell you which flat stretch you're in is overselling.
Ceilings that are not failures — Decline Mechanisms Hub. The fourth term names something most progress models lack: a completed limit, where the approach has been executed properly and has reached the end of what it can produce. Institutions hit this constantly and almost never diagnose it correctly, because the symptoms of a method at its ceiling and a method being executed badly are identical — flat results, no obvious error, effort undiminished. Neither side gives this alone: distinguishing a ceiling from a plateau requires evidence from outside the method, and a method at its ceiling is precisely a method that has stopped generating such evidence — which is why the diagnosis is almost always made late, and usually by someone who arrived from elsewhere.
Sharpest implication. The fourth stage is a ceiling, not a summit — and a four-part sequence naturally reads as a path, so readers reliably supply a fifth stage where the tradition supplies a discontinuity. That misreading is most of what goes wrong when this scheme travels.
Generative questions.
