Mbh 12.192.2a

"'"'I shall now describe the conduct of those called Parivrajakas. That is as follows: freeing themselves from attachment to the sacred fire, wealth, spouse and children, and robes, seats, beds, and such other objects of enjoyment, and breaking the bonds of affection, they roam about, regarding with an equal eye a clump of earth or rock and gold. They never set their hearts on the acquisition or enjoyment of the triple aggregate. They cast an equal eye on foes and friends and neutrals or strangers. They never injure, in thought, word, or deed, immobile things or creatures that are viviparous, or oviparous or born of filth, or called vegetables. They have no homes. They roam over hills and mountains, upon shores of rivers or seas, under shades of trees, and among temples of deities. They may go to towns or villages for residence. In a town, however, they should not live for more than five nights, while in a village their residence should never exceed one night. Entering a town or a village, they should, for the support of life, repair to the abodes of only Brahmanas of liberal deeds.[581] They should never ask for any alms except what is thrown into the (wooden) bowls they carry. They should free themselves from lust, wrath, pride, cupidity, delusion, miserliness, deceit, slander, vanity, and injury to living creatures. On this subject there are some verses: that person, who, observing the vow of taciturnity, roveth without giving any creature cause of fear, is never inspired with any fear himself by any creature. That learned person who performs the Agnihotra (not by kindling of external fire but) with the aid of the fire that is his own body, indeed, who poureth libations into his own mouth and upon the fire that exists in his own body, succeeds in attaining to numerous regions of felicity in consequence of that fire being fed with such libations obtained by a life of eleemosynation.
