The Buddha teaches on accomplishment in rational application of mind (2nd), 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 45.62 Accomplishment in Rational Application of Mind (2nd)

“Yadidaṁ—yonisomanasikārasampadā. Yonisomanasikārasampannassetaṁ, bhikkhave, bhikkhuno pāṭikaṅkhaṁ—ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāvessati, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkarissati.

Kathañca, bhikkhave, bhikkhu yonisomanasikārasampanno ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkaroti? Idha, bhikkhave, bhikkhu sammādiṭṭhiṁ bhāveti rāgavinayapariyosānaṁ dosavinayapariyosānaṁ mohavinayapariyosānaṁ …pe… sammāsamādhiṁ bhāveti rāgavinayapariyosānaṁ dosavinayapariyosānaṁ mohavinayapariyosānaṁ. Evaṁ kho, bhikkhave, bhikkhu yonisomanasikārasampanno ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāveti, ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkarotī”ti.

Sattamaṁ.

Sūriyapeyyālaṁ.

Tassuddānaṁ

Kalyāṇamittaṁ sīlañca,
chando ca attasampadā;
Diṭṭhi ca appamādo ca,
yoniso bhavati sattamaṁ.

Reference Translation by Bhikkhu Sujato (CC0).

“Yadidaṁ—yonisomanasikārasampadā.

“… accomplishment in rational application of mind.

Yonisomanasikārasampannassetaṁ, bhikkhave, bhikkhuno pāṭikaṅkhaṁ—ariyaṁ 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 rāgavinayapariyosānaṁ dosavinayapariyosānaṁ mohavinayapariyosānaṁ …pe… sammāsamādhiṁ bhāveti rāgavinayapariyosānaṁ dosavinayapariyosānaṁ mohavinayapariyosānaṁ.

It’s when a mendicant develops right view, right purpose, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion, which culminate in the removal of greed, hate, and delusion.

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.

Sūriyapeyyālaṁ.

Tassuddānaṁ

Kalyāṇamittaṁ sīlañca,

chando ca attasampadā;

Diṭṭhi ca appamādo ca,

yoniso bhavati sattamaṁ.
