Paṭhamasikkhattayasutta

“Tisso imā, bhikkhave, sikkhā. Katamā tisso? Adhisīlasikkhā, adhicittasikkhā, adhipaññāsikkhā.

“Mendicants, these are the three trainings. What three? The training in the higher ethics, the higher mind, and the higher wisdom.

Katamā ca, bhikkhave, adhisīlasikkhā? Idha, bhikkhave, bhikkhu sīlavā hoti …pe… samādāya sikkhati sikkhāpadesu. Ayaṁ vuccati, bhikkhave, adhisīlasikkhā.

And what is the training in the higher ethics? It’s when a mendicant is ethical, restrained in the monastic code, conducting themselves well and resorting for alms in suitable places. Seeing danger in the slightest fault, they keep the rules they’ve undertaken. This is called the training in the higher ethics.

Katamā ca, bhikkhave, adhicittasikkhā? Idha, bhikkhave, bhikkhu vivicceva kāmehi …pe… catutthaṁ jhānaṁ upasampajja viharati. Ayaṁ vuccati, bhikkhave, adhicittasikkhā.

And what is the training in the higher mind? It’s when a mendicant, quite secluded from sensual pleasures, secluded from unskillful qualities, enters and remains in the first absorption … second absorption … third absorption … fourth absorption. This is called the training in the higher mind.

Katamā ca, bhikkhave, adhipaññāsikkhā? Idha, bhikkhave, bhikkhu ‘idaṁ dukkhan’ti yathābhūtaṁ pajānāti …pe… ‘ayaṁ dukkhanirodhagāminī paṭipadā’ti yathābhūtaṁ pajānāti. Ayaṁ vuccati, bhikkhave, adhipaññāsikkhā. Imā kho, bhikkhave, tisso sikkhā”ti. Navamaṁ.

And what is the training in the higher wisdom? They truly understand: ‘This is suffering’ … ‘This is the origin of suffering’ … ‘This is the cessation of suffering’ … ‘This is the practice that leads to the cessation of suffering’. This is called the training in the higher wisdom. These are the three trainings.”
