of the house, and Brahman; on the top of the house or behind it for all living creatures; and the remainder must be strewn for the ancestors with the face turned to the south. Any one who omits these offerings before eating is a sinner.[201] At sunrise and sunset the Dvija is to pronounce the prayer Gayatri on pain of losing caste;[202] and every day he must pour libations to the saints, the gods, the spirits, the ancestors, and strangers. The forms of purification underwent further change and important extension. The new system, unlike the old custom, was not contented to remove defilement, when incurred, by the use of rules of purification, in which, in certain cases, traditional prayers and formulæ had to be pronounced in order to obviate the evil consequences, or drive away the bad spirits. In a large number of defilements the Brahmans saw something more than mere impurity; they were sins which must be removed by expiation. Their desire was not to expel the black spirits, but to eradicated and quench the false and sinful feelings in men, which gave rise to impurity. From the same point of view, and following the same path, they required that a man who had committed an offence, should not wait for the penalty of the court, but should punish himself, do penance of his own will, and by this voluntary punishment and expiation remove the consequences of his offence, not in this world only but in the next. The forms of expiation instituted by the Brahmans for the removal of impurity and offences consist of prayers, which at times have to be repeated a thousand times daily, of fasts more or less severe, and occupying more or less time, of corporal punishments, and in the case of grievous offences, of voluntary death or suicide. Any one who by misadventure has eaten forbidden food must perform the expiation of the moon, or the Santapana. The expiation of the moon consists in eating nothing but rice for a whole month; on the first day of the waning moon fifteen mouthfuls are to be taken, and a mouthful less each day till the sixteenth, when a total fast is to be kept; from this time for each day of the increase of the moon a mouthful more is to be taken till the fifteenth day.[203] The Santapana requires that the penitent should live for a day on the urine and dung of cows mingled with milk, and drink water boiled with kuça-grass; the day following he is to fast.[204] To atone for the forbidden food eaten unintentionally by an Arya in the course of a year, it was necessary to perform the penance of Prajapatya for twelve days.[205] On the first three days he eats in the morning only; on the next three, in the evening only; on the seventh, eighth, and ninth day he eats only what strangers give him, without asking; on the last three days he keeps a strict fast. Any one who intentionally eats what is forbidden is expelled by the members of his family from the family and caste. The Brahmans punished indulgence in intoxicating
