Bhagavā etadavoca: “Ekāyano ayaṁ, bhikkhave, maggo sattānaṁ visuddhiyā, sokaparidevānaṁ samatikkamāya, dukkhadomanassānaṁ atthaṅgamāya, ñāyassa adhigamāya, nibbānassa sacchikiriyāya, yadidaṁ cattāro satipaṭṭhānā. Katame cattāro? Idha, bhikkhave, bhikkhu kāye kāyānupassī viharati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ; vedanāsu vedanānupassī viharati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ; citte cittānupassī viharati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ; dhammesu dhammānupassī viharati ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ. Uddeso niṭṭhito.
