The passage

In one sentence

At the end there is no longer a skill but a passage: the mind turns away, steps back, turns towards — and what falls, falls for good.

In today's language

Chapter XXI is the chapter of the knowledges that no longer look like knowledges. It begins where the previous one left off: the practitioner has seen through the imperfections and goes on observing the coming up and the passing away.

Then something shifts. The coming up recedes, and what remains is the passing away — everywhere, without a break. From there it goes along a series that the book lists as knowledges and that reads more like states of mind: things appear as terror. As misery. Disenchantment comes. The wish to be free. Once more an effortful reflection.

And then that stops. What comes the book calls equanimity towards formations (saṅkhārupekkhā): the mind no longer reaches out and no longer pushes away. It sees the same as before and has nothing further in mind with it.

Upon that follows the knowledge of conformity — the last moment that still belongs to the accustomed — and then the moment to which the book gives a name and a position of its own: the knowledge of maturity, gotrabhū. It belongs to none of the seven purifications. It is the step across the threshold.

What comes after that is chapter XXII: path and fruit, four times. With each path certain fetters fall, and they fall in such a way that they do not come back.

Why this matters

Because here for the first time something happens that is no longer done. The whole book up to this point was instruction. At this place it says expressly: for one who wishes to bring about the first path knowledge there is nothing further to do in the matter — what was to be done, he has done.

That is not mystification but a sober statement about the structure of the way: the practice establishes conditions; it does not compel a result.

Canonical basis

SN 22.59 has the sequence of words that the manual unfolds here: disenchantment, dispassion, liberation, and the knowledge of liberation. What in the discourse is four words is several chapters in the book.

SN 56.11 is the first documented case: at the end of the first discourse the eye of truth opens for Koṇḍañña — “whatever is subject to arising is also subject to ceasing”. That is exactly the content the manual assigns to stream-entry.

SN 55.1 describes by what the stream-enterer is recognisable afterwards — not by an experience but by four things that no longer waver: confidence in the Buddha, the teaching and the community, and a virtue that no longer breaks.

And MN 107 sets the frame straight: the Buddha describes the whole way in order and says at the end that some arrive and some do not, although the same way was pointed out.

Components

• The knowledges (chapter XXI): arising and passing away — dissolution — terror — misery — disenchantment — the wish for deliverance — reflection — equanimity towards formations — conformity.
• The knowledge of maturity (gotrabhū): between the purifications, without a purification of its own.
• Four paths and four fruits (chapter XXII): stream-entry, once-return, non-return, arahantship.
• The fetters: with stream-entry there fall the view of a person, doubt and the clinging to rules and observances; with the third path sensual desire and ill will; with the fourth the rest.
• The blessing (chapter XXIII): what the whole unfolding of knowledge was good for.

Connection with other teachings

The four paths and fruits are the same division the discourses carry as “eight persons, four pairs”. The fetters are the canonical list. What is new in the manual is only the fine drawing of the transition — the moments immediately before and after the threshold.

And the arc closes: the view of a person, which fell at stage 4 as an insight, falls here as a fetter. That is the difference between understood and finished with.

Significance for practice

The practical yield of this chapter is paradoxical: it describes things one cannot practise. What one takes from it is therefore not a procedure but a measure.

The measure of SN 55.1 is the most usable, because it appeals not to experiences but to what lasts: confidence that no longer turns over, and virtue that no longer breaks. Something can be tested against that — against a remembered experience it cannot.

Common misinterpretations

“Equanimity towards formations is the goal.” It is the last state before the threshold and is itself still conditioned. The book lists it under purification by knowledge and vision of the way, not under deliverance.

“After stream-entry one is finished.” Three fetters fall, seven remain. That is why chapter XXII lists four paths and not one.

“Terror and misery are a step backwards.” They stand in the book as knowledges, not as disturbances — they are names for what the matter shows when one no longer looks away. The chapter before described precisely the pleasant states as a detour; these here are their counterpart.
