The daily Pit_ri_ya_gñ_a or Ancestor-worship is one of the five sacrifices, sometimes called the Great Sacrifices,[293] which every married man ought to perform day by day. They are mentioned in the G_ri_hya-sûtras (Â_s_v. III. 1), as Devaya_gñ_a, for the Devas, Bhûtaya_gñ_a, for animals, etc., Pit_ri_ya_gñ_a, for the Fathers, Brahmaya_gñ_a, for Brahman, _i.e._ study of the Veda, and Manushyaya_gñ_a, for men, _i.e._ hospitality, etc. Manu (III. 70) tells us the same, namely, that a married man has five great religious duties to perform: 1. The Brahma-sacrifice, _i.e._ the studying and teaching of the Veda (sometimes called Ahuta). 2. The Pit_ri_-sacrifice, _i.e._ the offering of cakes and water to the Manes (sometimes called Prâ_s_ita). 3. The Deva-sacrifice, _i.e._ the offering of oblations to the gods (sometimes called Huta). 4. The Bhûta-sacrifice, _i.e._ the giving of food to living creatures (sometimes called Prahuta). 5. The Manushya-sacrifice, _i.e._ the receiving of guests with hospitality (sometimes called Brâhmya huta).[294] The performance of this daily Pit_ri_ya_gñ_a, seems to have been extremely simple. The householder had to put his sacred cord on the right shoulder, to say "Svadhâ to the Fathers," and to throw the remains of certain offerings toward the south.[295] The human impulse to this sacrifice, if sacrifice it can be called, is clear enough. The five "great sacrifices" comprehended in early times the whole duty of man from day to day. They were connected with his daily meal.[296] When this meal was preparing, and before he could touch it himself, he was to offer something to the gods, a Vai_s_vadeva offering,[297] in which the chief deities were Agni, fire, Soma the Vi_s_ve Devas, Dhanvantari, the kind of Æsculapius, Kuhû and Anumati (phases of the moon), Pra_g_âpati, lord of creatures, Dyâvâ-p_ri_thivî, Heaven and Earth, and Svish_t_ak_ri_t, the fire on the hearth.[298] After having thus satisfied the gods in the four quarters, the householder had to throw some oblations into the open air, which were intended for animals, and in some cases for invisible beings, ghosts and such like. Then he was to remember the Departed, the Pit_ri_s, with some offerings; but even after having done this he was not yet to begin his own repast, unless he had also given something to strangers (atithis). When all this had been fulfilled, and when, besides, the householder, as we should say, had said his daily prayers, or repeated what he had learned of the Veda, then and then only was he in harmony with the world that surrounded him, the five Great Sacrifices had been performed by him, and he was free from all the sins arising from a thoughtless and selfish life.
