Now, let us hear what foods are recommended and how purity is to be maintained. The scriptures declare that one should partake of smooth, oil-free rice, as well as products derived from milk. In the same way, split pulses and similar foods are prescribed by Manu as wholesome sustenance. The roots and grains of various grasses, along with those from mountain trees, are also to be considered suitable for eating. Turning to matters of cleanliness, it is said that all types of bark garments may be purified simply with water, while cotton garments require the use of ash for proper purification. Earthen vessels, once rendered impure, regain their purity when reheated. As for items found on the road, of unknown origin, or handled by groups of servants, their status is different. Yet, the actions of children and the elderly, as well as the mouth of a child, are regarded as pure. Furthermore, the words spoken by the best among the twice-born, and water drops warmed by the sun, are considered pure. Purity within the home is achieved through smearing, scraping, sprinkling, sweeping, and general cleaning. For purification, clay, water, ash, and alkali are to be employed. Copper vessels and those used for washing are purified with ash and water. Other substances are rendered pure by removing any foul odor. Even animals have their rules: a donkey bearing a load is pure, and a dog is pure when it is seizing an animal. Objects that have been baked in a kiln are purified simply by the wind. When impurity is present on an object, the upper portion should be removed and discarded, and the remainder purified by sprinkling. However, if the impurity is unknown or was only known in the past, no purification is prescribed. If one touches something impure, or bears a corpse, it is necessary to bathe to regain cleanliness. Sometimes, mere sipping of water, touching a cow, and gazing at the sun are sufficient for purification. Water used for washing the feet, leftover food, feces, and urine should always be thrown outside the house. For deeper purity, one should bathe in sacred ponds, lotus-filled lakes, or flowing rivers. There are also cautions regarding association: one should not converse with a person hated by the people, a coward, or a woman of ill repute. Should one touch or speak with such persons, purification is achieved by looking at the sun. The scriptures then speak of those who are regarded as fallen, expelled, naked, or the lowest of men, such as outcastes. The characteristics of these persons are described in truth. Both the woman who has recently given birth and the one who has miscarried are called 'sūtikā', and their food is considered impure. One who neglects the worship of ancestors and gods is described as a eunuch. He who does not strive for the welfare of the next world is likened to a cat. One who is called a rat makes it difficult to regain purity after eating his food. He who always hates the virtues of others is referred to as a dog, and the gods call such a person a rooster, whose food is also impure. If such a person is not in distress, the learned declare him fallen. He who kills a cow, a Brahmin, or a woman is called defiled. Such people are called naked by the virtuous, and their food is impure. The one who abandons someone who has sought refuge is a cāṇḍāla, the lowest of men. One who eats from a pit must perform the cāndrāyana expiation after consuming such food. After eating the food of such a person, or even the food of a miser, a man is purified by fasting for three nights. However, a ritual cutting for a specific purpose should never be performed under any circumstances. Thus are the rules of food, purity, and conduct, as taught by the scriptures.
