[256] 52. "'The secure, the secure' (khemaṃ), friend, it is said. In what way, friend, has the secure been spoken of by the Blessed One?"
"Here, friend, a bhikkhu, quite secluded from sensual pleasures … enters and dwells in the first jhāna. To this extent too, friend, the secure has been spoken of by the Blessed One in a provisional sense (pariyāyena) …
"Again, furthermore, friend, a bhikkhu, by completely surmounting the base of neither-perception-nor-non-perception, enters and dwells in the cessation of perception and feeling; and, having seen with wisdom, his taints (āsava) are utterly destroyed. To this extent, friend, the secure has been spoken of by the Blessed One in the definitive sense (nippariyāyena)."
