"He who, after having offered food and libations to the Pitris, bathes in the Ganges, Satlaj, Vipáśá (Beyah), Saraswatí, or the Gomatí at Naimisha, expiates all his sins. The Pitris also say, 'After having received satisfaction for a twelvemonth, we shall further derive gratification by libations offered by our descendants at some place of pilgrimage, at the end of the dark fortnight of Mágha.' The songs of the Pitris confer purity of heart, integrity of wealth, prosperous seasons, perfect rites, and devout faith; all that men can desire. Hear the verses that constitute those songs, by listening to which all those advantages will be secured, oh prince, by you. 'That enlightened individual who begrudges not his wealth, but presents us with cakes, shall be born in a distinguished family. Prosperous and affluent shall that man ever be, who in honour of us gives to the Brahmans, if he is wealthy, jewels, clothes, land, conveyances, wealth, or any valuable presents; or who, with faith and humility, entertains them with food, according to his means, at proper seasons. If he cannot afford to give them dressed food, he must, in proportion to his ability, present them with unboiled grain, or such gifts, however trifling, as he can bestow. Should he be utterly unable even to do this, he must give to some eminent Brahman, bowing at the same time before him, sesamum-seeds adhering to the tips of his fingers, and sprinkle water to us, from the palms of his hands, upon the ground; or he must gather, as he may, fodder for a day, and give it to a cow; by which he will, if firm in faith, yield us satisfaction. If nothing of this kind is practicable, he must go to a forest, and lift up his arms to the sun and other regents of the spheres, and say aloud--I have no money, nor property, nor grain, nor any thing whatever it for an ancestral offering. Bowing therefore to my ancestors, I hope the progenitors will be satisfied with these arms tossed up in the air in devotion.' These are the words of the Pitris themselves; and he who endeavours, with such means as he may possess, to fulfil their wishes, performs the ancestral rite called a Śráddha."
