If the use of flesh as food could not be entirely forbidden to the Kshatriyas and Vaiçyas, the Brahman must live on milk and vegetables. But he might not drink the milk of a cow when in heat, or that has lately calved, or of a cow which had lost her calf, the milk of a camel, the red gum which exudes from trees, or anything from which oil has been pressed, or with which sesame has been mixed, or anything that from sweet has become sour. He might not eat anything kept over night, or any food into which lice have fallen, or which a cow has smelt, or anything touched by a dog. He might not take the food of a criminal, or prisoner, or usurer, or rogue, or hunter, or dog-trainer, or Çudra, or dancer, or washer-woman; or of a man who is submissive to his wife, or allows her infidelity, or into whose house the wife's paramour comes. All such food is unclean for the Brahman; and so also is food offered to him in anger, and that touched by a madman. Any one eating such things feeds on "bones, hair, and skin." With the same minute exactness, regulations are laid down for the Brahman as to the mode and position in which he is to take the permitted kinds of food; with what parts of the hand or finger he is to perform his ablutions, how he is to demean himself on all the occasions of life, when travelling, etc., in order to preserve his purity and sanctity. With equal detail we are told how the Brahman is to perform the natural requirements of the body, and the purifications thereby rendered necessary.[211] The least neglect in the fulfilment of these endless duties, which it was impossible to keep in view at once, and more impossible still to bear in mind at every moment, even with the most devoted attention, might bring on centuries of punishment and endless regenerations, unless it was expiated. The prescripts of the Brahmans have been thoroughly carried out, and even the other orders to this time fulfil their daily duties. The Brahman utters his morning prayer, bathes in the stream, the fountain, the pool, or in his house, performs the invocations to the gods, spirits, and ancestors, and then with his wife and child, who also have bathed, offers prayers and gifts to the protecting deities of the house.[212] Among wealthy families of the Kshatriyas and Vaiçyas the morning prayers after the bath are performed under the guidance of the priest of the house. No one eats the morning meal till the grains of rice have been scattered for the Maruts, the gods of water and trees, and the special deity of the house. No Hindoo proceeds to his work till he has purified himself and performed his devotions. The Brahman does not open his book, neither smith nor carpenter takes in hand his tool, till he has uttered prayers. They neither stand up nor sit down, nor leave the room, nor sneeze, nor vomit, without the prescribed formula.
