Then a mendicant went up to the Buddha … and said: Atha kho aññataro bhikkhu yena bhagavā tenupasaṅkami …pe…

“Sir, may the Buddha please teach me Dhamma in brief. When I’ve heard it, I’ll live alone, withdrawn, diligent, keen, and resolute.” “sādhu me, bhante, bhagavā saṅkhittena dhammaṁ desetu, yamahaṁ bhagavato dhammaṁ sutvā eko vūpakaṭṭho appamatto ātāpī pahitatto vihareyyan”ti.

“Well then, mendicant, you should purify the starting point of skillful qualities. “Tasmātiha tvaṁ, bhikkhu, ādimeva visodhehi kusalesu dhammesu. What is the beginning of skillful qualities? Ko cādi kusalānaṁ dhammānaṁ? Give up bad conduct by way of body, speech, and mind and develop good conduct by way of body, speech, and mind. Idha tvaṁ, bhikkhu, kāyaduccaritaṁ pahāya kāyasucaritaṁ bhāvessasi. Vacīduccaritaṁ pahāya vacīsucaritaṁ bhāvessasi. Manoduccaritaṁ pahāya manosucaritaṁ bhāvessasi. When you’ve done this, you should develop the four kinds of mindfulness meditation, depending on and grounded on ethics. Yato kho tvaṁ, bhikkhu, kāyaduccaritaṁ pahāya kāyasucaritaṁ bhāvessasi, vacīduccaritaṁ pahāya vacīsucaritaṁ bhāvessasi, manoduccaritaṁ pahāya manosucaritaṁ bhāvessasi, tato tvaṁ, bhikkhu, sīlaṁ nissāya sīle patiṭṭhāya cattāro satipaṭṭhāne bhāveyyāsi.

What four? Katame cattāro? Meditate observing an aspect of the body—keen, aware, and mindful, rid of covetousness and displeasure for the world. Idha tvaṁ, bhikkhu, kāye kāyānupassī viharāhi ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ; Meditate observing an aspect of feelings … vedanāsu …pe… mind … citte …pe… principles—keen, aware, and mindful, rid of covetousness and displeasure for the world. dhammesu dhammānupassī viharāhi ātāpī sampajāno satimā, vineyya loke abhijjhādomanassaṁ. When you develop the four kinds of mindfulness meditation in this way, depending on and grounded on ethics, you can expect growth, not decline, in skillful qualities, whether by day or by night.” … Yato kho tvaṁ, bhikkhu, sīlaṁ nissāya sīle patiṭṭhāya ime cattāro satipaṭṭhāne evaṁ bhāvessasi, tato tuyhaṁ, bhikkhu, yā ratti vā divaso vā āgamissati vuddhiyeva pāṭikaṅkhā kusalesu dhammesu, no parihānī”ti …pe…

And that mendicant became one of the perfected. aññataro ca pana so bhikkhu arahataṁ ahosīti.

Sattamaṁ.
