1“Mendicants, there are four ways of practice. What four?

2Painful practice with slow insight,

5pleasant practice with swift insight.

6Of these, the painful practice with slow insight is said to be inferior in both ways: because it’s painful and because it’s slow. This practice is said to be inferior in both ways.

7The painful practice with swift insight is said to be inferior because it’s painful.

8The pleasant practice with slow insight is said to be inferior because it’s slow.

9The pleasant practice with swift insight is said to be superior in both ways: because it’s pleasant, and because it’s swift. This practice is said to be superior in both ways.

10These are the four ways of practice.”
