1Then a mendicant went up to the Buddha … and said:

2“Sir, may the Buddha please teach me Dhamma in brief. When I’ve heard it, I’ll live alone, withdrawn, diligent, keen, and resolute.”

3“Well then, mendicant, you should purify the starting point of skillful qualities. What is the beginning of skillful qualities? Give up bad conduct by way of body, speech, and mind and develop good conduct by way of body, speech, and mind. When you’ve done this, you should develop the four kinds of mindfulness meditation, depending on and grounded on ethics.

4What four? Meditate observing an aspect of the body—keen, aware, and mindful, rid of covetousness and displeasure for the world. Meditate observing an aspect of feelings … mind … principles—keen, aware, and mindful, rid of covetousness and displeasure for the world. 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.” …

5And that mendicant became one of the perfected.
