Preached to the monks, with Ánanda at their head, by the Buddha at Kammassadhamma in the Kuru country. It deals with real Permanence (ánańjasappáya) and with the various ways of meditating on impassibility and the attainments and true release. True deathlessness is only the heart's deliverance (anupádá cittassa vimokkho), and there are several stages of the paths that lead to it (M.ii.261ff). Buddhaghosa (MA.ii.851) says that this sutta described the arahantship of the Sukkhavipassaká. Arahantship is mentioned in nine different connections in the sutta, which is therefore praised as being well taught (sukathitam).
