According to the Avesta, the soul of man is kept pure by truthfulness, industry, and diligence, by good thoughts, good words and acts, which advance the kingdom of life; the body is to be kept free from dirt and the house from filth and dead creatures; from all that belongs to the evil spirits and is in their power. The soul of man is created pure; but from the first the body has certain impure parts, and the defilement which Angromainyu brought into the bodies of men. This defilement consists in the spittle, the excrements, dead skin, sores, etc; in everything that has an unpleasant smell, or is removed from the living body, like the hair and nails. These when cut are dead, and therefore belong to the kingdom of darkness; hence in Iran as in India they are impure things. "Wherever cut hair and nails lie," says the book of the law, "there the Daevas gather to these unholy places; there the impure animals come, which men call lice. Therefore carry away--so saith Auramazda--cut hair and nails, ten paces from the pure men, twenty from the fire, thirty from the water, fifty from the sacred bundle of rods. Dig a hole below the house in the earth, pronounce the prayer Ahunavairya thrice, six times, nine times, and then say: To thee, O bird, Asho-zusta, I show these nails. These nails I dedicate to thee; may they be thy lances, thy swords, thy bow, thy swift-flying arrows, thy sling-stones against the Mazanian Daevas. If these nails are not announced to the bird Asho-zusta, they are weapons for, not against, the Daevas."[361] Spittle is among the worst impurities. The priests could only approach the fire with veiled mouth, and even now the Parsees invariably cover the mouth in praying. They eat in silence, and two never use the same spoon, because the food would then be polluted by spittle. The removal of the excrements requires as much care in the Avesta as it did in the Brahmanic law, and the Vendidad gives minute regulations in regard to these matters.[362] A man is rendered impure by excess and debauchery; a woman by her courses, "by marks and blood," and by the birth of a child. She must be carried to an elevated place in the dwelling, which is strewn with dry sand, fifteen paces from the fire, from water, and the sacred bundle of rods, "at a distance also from the trees," and so placed that she cannot see the fire on the hearth. No one may touch her. Only a definite amount of certain kinds of food can be given to her, and that in metal jars, because these contract the least amount of impurity, and are most easily cleansed; the person who brings the food must remain three paces distant from her bed. After childbirth a woman is unclean for three days; then she must wash her body with water and gomez. If she has had a miscarriage her body is also polluted by the dead child: she must be placed thirty paces away from the fire and the sacred objects of the house, and must pass a longer period on
