Aṅguttara Nikāya 4.71 8. Apaṇṇakavagga Padhānasutta

“Catūhi, bhikkhave, dhammehi samannāgato bhikkhu apaṇṇakappaṭipadaṁ paṭipanno hoti, yoni cassa āraddhā hoti āsavānaṁ khayāya.

“Mendicants, when a mendicant has four things their practice is a sure bet, and they have laid the groundwork for ending the defilements.

Katamehi catūhi?

What four?

Idha, bhikkhave, bhikkhu sīlavā hoti, bahussuto hoti, āraddhavīriyo hoti, paññavā hoti.

It’s when a mendicant is ethical, learned, energetic, and wise.

Imehi kho, bhikkhave, catūhi dhammehi samannāgato bhikkhu apaṇṇakappaṭipadaṁ paṭipanno hoti, yoni cassa āraddhā hoti āsavānaṁ khayāyā”ti.

When a mendicant possesses these four things their practice is a sure bet, and they have laid the groundwork for ending the defilements.”

Paṭhamaṁ.
