After touching a menstruous woman, a horse, a jackal, and other animals, or a woman recently delivered of a child, or people of low caste, one should bathe for the sake of purification; and so should those who have carried a corpse. After touching an oily human bone a man becomes clean when he has bathed; after touching a dry human hone he becomes clean by rinsing out his mouth, or by touching a cow, or by gazing at the sun. Moreover one should not disregard blood, spittle, and unguents for the body.

A wise man should never stand in gardens and other places in the afternoons. Nor should one hold converse with a woman hated by the populace or with a widow.
