AN 4:13 The Four Right Efforts
Translated from the Pali by Nyanaponika Thera and Bhikkhu Bodhi
There are four right efforts, O monk. What four?
Herein a monk rouses his will not to permit the arising of evil, unwholesome states that have not arisen—to abandon evil, unwholesome states already arisen—to arouse wholesome states that have not yet arisen—to maintain wholesome states already arisen and not allow them to disappear; he makes an effort (for it), stirs up his energy exerts his mind and strives.
