At one time the venerables Sāriputta, Mahāmoggallāna, and Anuruddha 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, they speak of the one called ‘a trainee’. How is a trainee defined?” “Reverends, a trainee is someone who has partly developed the four kinds of mindfulness meditation.

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

They meditate observing an aspect of feelings … mind … principles—keen, aware, and mindful, rid of covetousness and displeasure for the world.
