The Tipiṭaka in Three Languages

Pariññātasutta

Suttapiṭaka · Saṁyuttanikāya · Mahāvaggasaṁyutta · Vol. 19 · Section 811

[811] …dwells contemplating feelings (vedanā) in feelings, ardent, clearly comprehending, mindful, having removed covetousness and grief regarding the world. As he dwells contemplating feelings in feelings, feeling becomes fully understood (pariññātā). Because feelings have been fully understood, the deathless (amata) is realized.
