Things infested with hair-lice, or sniffed at by cattle, or infested with ñies should be sprinkled with earth water and ashes to be cleansed, my son; things made of udumbara wood[2] with vinegar; tin and lead with salt. Brass things are cleaned with ashes and water; and the over-flows of fluids are pure. A thing soiled by ordure is cleaned with earth and water and by removing the smell; and other such-like things by removing the colour and smell.

Water is pure that has satisfied cattle, that is in its natural state, that is lying on the earth; and likewise flesh that has been slain by Caṇḍālas, Kravyādas and others. And clothes and other things lying on the high-road are said to he made pure by the wind. Dust, fire, a horse, a cow, the shade, the rays of the sun and moon, the wind, the earth, drops of water, and mosquitoes and other insects inflict no contamination though they may have been in contact with what is corrupt. A goat and a horse are pure as regards their face; but the face of a cow or calf is not pure when the mother is in milk; a hawk is pure when it knocks fruit down. A seat, a bed, a carriage, boats, and grass on the road—they are purified by the rays of the moon and sun and by the wind, in the same way as articles of trade.
