MBh 12.185.4

I shall now describe the conduct of the Parivrajakas, which is as follows : alienating themselves from attachment to the sacred fire, wealth, wife and children, and robes, seats, beds, and such other objects of enjoyment, and snapping the fetters of affection, they walk about, regarding with an equal eye a clump of earth or rock and gold. They never think of acquiring or enjoying the threefold objects of life. They regard impartially foes and friends and neutrals or strangers. They never injure, in thought, word, or deed, immobile objects, or creatures that are viviparous, or oviparous, or born of fifth, or called vegetables. They have no homes. They road over hills and mountains, upon shores of rivers or oceans, under shades of trees, and among temples of gods, They may go to towns or villages for living. In one town, however, they should not live for more than five nights, while in the same village they should not live for more than one night. Entering a town or a village, they should , for maintaining their life, go to the houses of liberal Brahmanas only. They should never ask for any alms but accept what is put into the bowls they carry. They should free themselves from lust, anger, pride, cupidity, delusion, miserliness, deceit, slander, vanity, and injury to creatures.
