Why this discourse

This discourse opens round four's exterior half — and, with it, the vagga's own final three discourses: the identical timeless impermanent/suffering/not-self cycle already run for the interior sense fields (SN 35.222-224), now applied to sights, sounds, smells, tastes, touches, and ideas, all six named together on a single line.

Reading guide

The exterior sense fields, named together

“Sights, mendicants, are impermanent. Sounds … smells … tastes … touches … and ideas are impermanent…” — the root text still marks each field separately, but Sujato's own English compresses them into a compact, single-sentence list.

Three discourses from the vagga's own close

SN 35.225-227 will complete round four, this vagga, and — unlike any other round in this vagga — carry the vagga's own closing colophon and uddāna at their own final discourse, SN 35.227.

Key terms

bāhirāyatana — the six exterior sense fields — sights, sounds, smells, tastes, touches, and ideas, this discourse's own new subject
rūpā…dhammā — sights…ideas — the six exterior sense fields, named together in this discourse's own compact list
anicca — impermanent — the quality declared here, the first of the exterior half's own three-quality cycle in round four
ajjhattikāyatana — the six interior sense fields — already completed at SN 35.222-224, contrasted here with the exterior fields
aniccasutta — “The Discourse on Impermanence” — sharing its own title with SN 35.222's own interior counterpart and, further back, SN 22.12

The text

The complete discourse: the declaration, naming each of the six exterior sense fields, then the liberation formula in compressed form. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1“Mendicants, sights, sounds, smells, tastes, touches, and ideas are impermanent. Seeing this … They understand: ‘… there is nothing further for this place.’”
