“A wise man should not resort to other men’s wives. Adultery destroys the religious acts and the life of man. Nothing indeed is so short-lived in the world, as a man’s intercourse with another’s wife here.

“Let him perform the worship of the gods, and the cere monies to fire, and the respectful salutation to his guru, and also the ceremony of eating his food, after duly rinsing out his mouth. Facing eastwards or northwards he should reverently rinse out his mouth, my son, with frothless, inodorous, pure and holy water. He should avoid the five earths from beneath water, from a habitation, from an ant-hill, from ground infested with mice, and where purificatory actions &c. have been carried on. After washing his hands and feet and sprinkling water on them he should, with his face between his knees, and composed mind, rinse out his mouth. He should drink water three or four times after twice wiping the sides of his mouth, the apertures of the body, and his head. After duly rinsing out his mouth with water, being pure, he should perform the ceremony to the gods, the ṛṣis, and the pitṛs diligently. A man should always perform the ceremonies, preserving a composed mind. A wise man should rinse out his mouth, after he has sneezed, or spitten out, or donned his raiment. After a sneeze, and licking, and a vomit, and spitting &c., he should rinse out his mouth, touch a cow’s back, and look at the sun; and he should holdup his right ear, since this is in his power; in the absence of the former, he should do the latter; if the former be wanting, it is desirable to do the latter.
