Ekaṁ samayaṁ āyasmā ca anuruddho āyasmā ca sāriputto āyasmā ca mahāmoggallāno sākete viharanti kaṇḍakīvane. Atha kho āyasmā ca sāriputto āyasmā ca mahāmoggallāno sāyanhasamayaṁ paṭisallānā vuṭṭhitā yenāyasmā anuruddho tenupasaṅkamiṁsu; upasaṅkamitvā āyasmatā anuruddhena saddhiṁ sammodiṁsu. Sammodanīyaṁ kathaṁ sāraṇīyaṁ vītisāretvā ekamantaṁ nisīdiṁsu. Ekamantaṁ nisinno kho āyasmā sāriputto āyasmantaṁ anuruddhaṁ etadavoca: “sekhenāvuso anuruddha, bhikkhunā katame dhammā upasampajja vihātabbā”ti?

At Thorny Wood (1st)

At one time the venerables Anuruddha, Sāriputta, and Mahāmoggallāna were staying near Sāketa in the Thorny Wood. Then in the late afternoon, Sāriputta and Mahāmoggallāna came out of retreat, went to Anuruddha, and exchanged greetings with him. When the greetings and polite conversation were over, they sat down to one side. Sāriputta said to Anuruddha: “Reverend Anuruddha, what things should a trainee mendicant enter and remain in?”

“Sekhenāvuso sāriputta, bhikkhunā cattāro satipaṭṭhānā upasampajja vihātabbā. Katame cattāro? Idhāvuso, bhikkhu kāye kāyānupassī viharati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ; vedanāsu …pe… citte …pe… dhammesu dhammānupassī viharati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ— sekhenāvuso sāriputta, bhikkhunā ime cattāro satipaṭṭhānā upasampajja vihātabbā”ti.

“Reverend Sāriputta, a trainee mendicant should enter and remain in the four kinds of mindfulness meditation. What four? It’s when a mendicant meditates by observing an aspect of the body—keen, aware, and mindful, rid of covetousness and displeasure for the world. They meditate observing an aspect of feelings … mind … principles—keen, aware, and mindful, rid of covetousness and displeasure for the world. A trainee mendicant should enter and remain in these four kinds of mindfulness meditation.”
