Tena kho pana samayena bhagavā bhikkhū nib­bā­na­paṭi­saṃ­yuttāya dhammiyā kathāya sandasseti samādapeti samuttejeti sampahaṃseti. Tedha bhikkhū aṭṭhiṃ katvā manasi katvā sabbaṃ cetaso samannāharitvā ohitasotā dhammaṃ suṇanti.

“Nissitassa calitaṃ, anissitassa calitaṃ natthi. Calite asati passaddhi, passaddhiyā sati nati na hoti. Natiyā asati āgatigati na hoti. Āgatigatiyā asati cutūpapāto na hoti. Cutūpapāte asati nevidha na huraṃ na ubhaya­manta­rena. Esevanto dukkhassā”ti.

Catutthaṃ.
