Parinibbānasutta

Suttapiṭaka · Saṁyuttanikāya · Sagāthāvaggasaṁyutta · Vol. 15 · Section 620

[620] On one occasion the Blessed One was dwelling at Kusinārā, at Upavattana, in the sāla grove of the Mallas, between the twin sāla trees, at the time of his final Nibbāna (parinibbāna). Then the Blessed One addressed the bhikkhus: "Come now, bhikkhus, I address you: conditioned things (saṅkhārā) are of a nature to decay; strive to accomplishment through diligence." This was the Tathāgata's final utterance.
