378. The Bhikshu whose body and tongue and mind are quieted, who is collected, and has rejected the baits of the world, he is called quiet.
379. Rouse thyself by thyself, examine thyself by thyself, thus self-protected and attentive wilt thou live happily, O Bhikshu!
380. For self is the lord of self, self is the refuge of self; therefore curb thyself as the merchant curbs a good horse.
DHAMMAPADA, Chapter 25. THE BHIKSHU (MENDICANT)
