“Tayome, bhikkhave āsavā. Katame tayo? Kāmāsavo, bhavāsavo, avijjāsavo— ime kho, bhikkhave, tayo āsavā. Imesaṁ kho, bhikkhave, tiṇṇannaṁ āsavānaṁ pahānāya cattāro satipaṭṭhānā bhāvetabbā.

Defilements

“Mendicants, there are these three defilements. What three? The defilements of sensuality, desire to be reborn, and ignorance. These are the three defilements. The four kinds of mindfulness meditation should be developed to give up these three defilements.

Katame cattāro? Idha, bhikkhave, 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, bhikkhave, tiṇṇannaṁ āsavānaṁ pahānāya ime cattāro satipaṭṭhānā bhāvetabbā”ti.

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. These four kinds of mindfulness meditation should be developed to give up these three defilements.”
