Dhp 182-184 · The Buddha (The Awakened)
Difficult (to obtain) is the conception of men, difficult is the life of mortals, difficult is the hearing of the True Law, difficult is the birth of the Awakened (the attainment of Buddhahood). Not to commit any sin, to do good, and to purify one's mind, that is the teaching of (all) the Awakened. The Awakened call patience the highest penance, long-suffering the highest Nirvana; for he is not an anchorite (pravragita) who strikes others, he is not an ascetic (sramana) who insults others.
