Why this chapter

Chapter 20 taught how to recognize the ten experiences that can be mistaken for the path and return attention to the plain observation of rise and fall. Chapter 21 opens the sixth purification by tracing what that properly reoriented contemplation actually develops into: a sequence of insight-knowledges, each building on the last, moving from simply watching phenomena arise and pass to a settled equanimity mature enough to give way to the supramundane path itself.

Reading guide

A sequence, not a single leap

Rather than describing insight as one sudden event, the chapter traces a graduated sequence of named stages, each a genuine advance on the one before, with contemplation deepening step by step rather than jumping directly from ordinary observation to full realization.

From arising-and-passing to passing alone

As the ten experiences from Chapter 20 settle, attention narrows: rather than noticing both the arising and passing of phenomena, the maturing contemplation increasingly registers dissolution specifically — phenomena's constant breaking-up.

Fear, danger, disenchantment

As this narrowed seeing of constant dissolution deepens, a related cluster of insight-knowledges follows: seeing all conditioned phenomena as fearful, seeing the danger inherent in them, and a matured, dispassionate disenchantment — not despair, but a settled seeing-through of what conditioned existence actually has to offer.

The wish to be free, and looking for the way out

This disenchantment gives rise to a genuine wish for deliverance from the whole conditioned process, followed by a renewed, more deliberate re-examination of the three characteristics, undertaken specifically in search of a way out.

Equanimity about formations

The sequence's peak follows: a stable, mature equanimity toward all conditioned phenomena, neither pursuing nor pushing any of them away, described as the furthest point ordinary, not-yet-supramundane insight can reach on its own.

Conformity, and the threshold

From that equanimity, a further knowledge arises that the chapter describes as conforming to both everything already contemplated and to what is about to follow — functioning as a bridge to a single moment in which the mind, for the first time, takes Nibbāna itself as its object: the very threshold of the supramundane path Chapter 22 will describe.

What follows

Chapter 22 turns to the seventh and final purification, describing that threshold moment itself and the four supramundane paths and fruits it opens onto.
