Why this chapter

Chapter 21 traced insight to its very threshold — a moment where the mind first takes Nibbāna as object. Chapter 22 opens the seventh and final purification by describing what happens at that threshold and beyond: the path-moment itself, immediately followed by its fruit, occurring across four distinct levels that mark the actual, definitive elimination of specific defilements — the purification the whole work's own title most precisely refers to.

Reading guide

The path-moment itself

Following the threshold Chapter 21 described, a single instantaneous event, the path-consciousness, arises, taking Nibbāna directly as its object. The chapter is specific that this event occurs only once for any given stage — it is never repeated.

Path and fruit

The path-moment is immediately followed, without any gap, by a corresponding fruition: several moments of consciousness that also take Nibbāna as their object. Together, path and fruit at each stage constitute what the chapter treats as the actual attainment.

Four stages, ten fetters removed in groups

The chapter traces this path-and-fruit event across four levels, each eliminating a specific subset of ten traditional fetters that bind a being to continued suffering. Stream-entry removes the first three: personality view, doubt, and clinging to rules and observances. Once-returning weakens, without fully removing, sensual desire and ill will. Non-returning eliminates those two entirely. And arahantship removes the remaining five — desire for fine-material and immaterial existence, conceit, restlessness, and ignorance — completing the process.

What each stage guarantees

The chapter is specific about what each level secures going forward: a stream-enterer is guaranteed no more than seven further lives and no rebirth in the lower realms; a once-returner, at most one further return to this particular world; a non-returner, no further rebirth in the sense-sphere at all; and an arahant, full and complete liberation, with nothing further left to attain.

Reviewing what has been attained

After each path-and-fruit event, the chapter describes a further reflective knowledge in which a practitioner reviews what was just attained, what defilements remain, and what remains to be done, before the process, where applicable, begins again toward the next stage.

Why this is the definitive purification

Everything from purification of virtue onward has prepared the ground for this. The four path-moments are what the chapter treats as the actual, irreversible elimination of specific defilements, in contrast to the earlier purifications, which readied the ground rather than accomplishing this directly.

What follows

Chapter 23, the work's closing chapter, turns from the process itself to the benefits this entire training is said to bring, closing the book Buddhaghosa opened by defining virtue back in Chapter 1.
