The Buddha teaches on accomplishment in rational application of mind (1st), showing how a mendicant develops and cultivates the noble eightfold path with factors that rely on seclusion, fading away, and cessation, ripening as letting go.

SN 45.69 Accomplishment in Rational Application of Mind (1st)

“Yadidaṁyonisomanasikārasampadā. Yonisomanasikārasampannassetaṁ, bhikkhave, bhikkhuno pāṭikaṅkhaṁariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāvessati, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkarissati.

Kathañca, bhikkhave, bhikkhu yonisomanasikārasampanno ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkaroti? Idha, bhikkhave, bhikkhu sammādiṭṭhiṁ bhāveti vivekanissitaṁ virāganissitaṁ nirodhanissitaṁ vossaggapariṇāmiṁ …pe… sammāsamādhiṁ bhāveti vivekanissitaṁ virāganissitaṁ nirodhanissitaṁ vossaggapariṇāmiṁ. Evaṁ kho, bhikkhave, bhikkhu yonisomanasikārasampanno ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkarotī”ti.

Sattamaṁ.

Reference Translation by Bhikkhu Sujato (CC0).

“Yadidaṁyonisomanasikārasampadā.

“… accomplishment in rational application of mind.

Yonisomanasikārasampannassetaṁ, bhikkhave, bhikkhuno pāṭikaṅkhaṁariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāvessati, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkarissati.

A mendicant accomplished in rational application of mind can expect to develop and cultivate the noble eightfold path.

Kathañca, bhikkhave, bhikkhu yonisomanasikārasampanno ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkaroti?

And how does a mendicant accomplished in rational application of mind develop and cultivate the noble eightfold path?

Idha, bhikkhave, bhikkhu sammādiṭṭhiṁ bhāveti vivekanissitaṁ virāganissitaṁ nirodhanissitaṁ vossaggapariṇāmiṁ …pe… sammāsamādhiṁ bhāveti vivekanissitaṁ virāganissitaṁ nirodhanissitaṁ vossaggapariṇāmiṁ.

It’s when a mendicant develops right view, right purpose, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion, which rely on seclusion, fading away, and cessation, and ripen as letting go.

Evaṁ kho, bhikkhave, bhikkhu yonisomanasikārasampanno ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkarotī”ti.

That’s how a mendicant accomplished in rational application of mind develops and cultivates the noble eightfold path.”

Sattamaṁ.
