[390] 12. Thus have I heard. On one occasion the Blessed One was dwelling at Sāvatthī in the Eastern Park, in the mansion of Migāra's mother. Now on that occasion — it being the uposatha day of the fifteenth, on the night of the full moon at its full — the Blessed One was seated in the open air surrounded by the Saṅgha of bhikkhus. Then the Blessed One, having surveyed the utterly silent Saṅgha of bhikkhus, addressed the bhikkhus:
"'Bhikkhus, as to those wholesome (kusala) dhammas that are noble, emancipating (niyyānika), leading to full awakening (sambodhi) — what, bhikkhus, is the reason (upanisā) for your listening to those wholesome dhammas that are noble, emancipating, leading to full awakening?' — if, bhikkhus, there should be questioners who ask thus, they should be answered thus: 'Just for the sake of knowledge (ñāṇa), as it really is (yathābhūta), of dhammas in dyads (dvayatā).' 'And what dyad do you speak of?' 'This is suffering (dukkha); this is the origin (samudaya) of suffering' — this is one contemplation. 'This is the cessation (nirodha) of suffering; this is the way of practice (paṭipadā) leading to the cessation of suffering' — this is the second contemplation. Bhikkhus, for a bhikkhu who dwells thus rightly contemplating the dyads — heedful, ardent (ātāpī), and resolute — one of two fruits is to be expected: final knowledge (aññā) in this very life or, if there is a residue of clinging, the state of a non-returner (anāgāmī)."
This is what the Blessed One said. Having said this, the Well-Farer (Sugata),
the Teacher, further said this:
