Shanti Parva 243.9

In this mode of life. the scriptures hold that a portion of food, should be given to every creature, to one, who for the sake of show, keeps his nails and beard, to one who from pride shows what his own (religious) practises are, to one who has unduly abandoned his sacred fire, and even to one who has injured his preceptor. A house holder should give (food) to Brahmacharins and Sanyasins.
