Mbh 12.193.2a

"'Bhishma said, "They that are of bad conduct, of bad acts, of wicked understanding, and excessive rashness, are called evil or wicked men. They, however, that are called good are distinguished by purity of conduct and practices. They are good men who never answer calls of nature on the high roads, in cow-pens, or in fields overgrown with paddy. Having finished the necessary acts one should perform his ablutions in river-water and gratify the deities with oblations of water. This is said to be the duty of all men. Surya should be always worshipped. One should not sleep after sunrise. Morning and evening the prayers (ordained in the scriptures) should be said, sitting with face turned towards the east and towards the west respectively. Washing the five limbs,[589] one should eat silently with face turned towards the east. One should never disparage the food which one is to eat. One should eat food that is good to the taste. After eating one should wash one's hands and rise.[590] One should never go to sleep at night with wet feet. The celestial Rishi Narada said that these are indications of good conduct. One should every day circumambulate a sacred spot, a bull, a sacred image, a cow-pen, a place where four roads meet, a pious Brahmana, and sacred tree. One should not make distinctions between one's guests and attendants and kinsmen in matters of food. Equality (in this respect) with servants is applauded. Eating (twice a day) in the morning and evening is an ordinance of the gods. It is not laid down that one should eat (once more) at any intermediate period. He who eats according to this rule acquires the merit of a fast.[591] At the hours ordained for Homa one should pour libations on the sacred fire. Without seeking the companionship of other people's wives, the man of wisdom who seeks his own wife in her season acquires the merit of Brahmacharyya. The remnants of a Brahmana's dish are like ambrosia.
