21. Heedfulness is the path to the Deathless. Heedlessness is the path to death. The heedful die not. The heedless are as if dead already.
22. Clearly understanding this excellence of heedfulness, the wise exult therein and enjoy the resort of the Noble Ones.
The Deathless (amata) is a synonymy for nibbāna.
