Monks, I know not of any other single thing of such power to cause the arising of good thoughts if not yet arisen, or to cause the waning of evil thoughts if already arisen, as heedfulness. In him who is heedful, good thoughts not yet arisen, do arise, and evil thoughts, if arisen, do wane
The man who delights in mindfulness and regards heedlessness with dread, is not liable to fall away. He is in the vicinity of Nibbana.
