1On one occasion the Venerable Sāriputta and the Venerable Mahāmoggallāna and the Venerable Anuruddha were dwelling at Saketa in the Thornbush Grove. Then, in the evening, the Venerable Sāriputta and the Venerable Mahāmoggallāna emerged from seclusion, approached the Venerable Anuruddha, and exchanged greetings with him. When they had concluded their greetings and cordial talk, sn.v.175 they sat down to one side, and the Venerable Sāriputta said to the Venerable Anuruddha:

"Friend Anuruddha, it is said, ‘A trainee, a trainee.’ In what way, friend, is one a trainee?"

"It is, friend, because one has partly developed the four establishments of mindfulness that one is a trainee.

2What four? Here, friends, a bhikkhu dwells contemplating the body in the body … feelings in feelings … mind in mind … phenomena in phenomena, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. It is because one has partly developed these four establishments of mindfulness that one is a trainee."

Sammodanīyaṁ kathaṁ sāraṇīyaṁ vītisāretvā ekamantaṁ nisīdiṁsu. Ekamantaṁ nisinno kho āyasmā sāriputto āyasmantaṁ anuruddhaṁ etadavoca:

"‘Sekho, sekho’ti, āvuso anuruddha, vuccati. Kittāvatā nu kho, āvuso, sekho hotī"ti?

"Catunnaṁ kho, āvuso, satipaṭṭhānānaṁ padesaṁ bhāvitattā sekho hoti.

2Katamesaṁ catunnaṁ? Idhāvuso, bhikkhu kāye kāyānupassī vihārati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ; vedanāsu … pe … citte … pe … dhammesu dhammānupassī vihārati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ. Imesaṁ kho, āvuso, catunnaṁ satipaṭṭhānānaṁ padesaṁ bhāvitattā sekho hotī"ti.

Chaṭṭhaṁ.
