During the twelfth month they should be given all the various kinds of eatables and fees should be given to them every month The Brâhmaṇas should put on pure clothes (never torn clothes) and perform sacrifice in the noon and the devotee should always remain with the Brāhmaṇas which pleases Indra and other gods and for the satisfaction of the gods animal sacrifice should also be made. Afterwards Agniṣṭoma sacrifice should also be performed, afterwards Purṇāhuti is to be duly performed. In one hundred Homas two hundred Purṇāhutis are to be performed, in one thousand (1,000) Homas twice that (i.e.) 2,000 Purṇāhutis are to be performed, thus up to one lākh Homas, this rule of doubling is to be followed. The Brâhmaṇas should then offer the sacrificial offerings for the Puroḍāśa for the satisfaction of the Devas. Afterwards the devotee should adore the manes, and offer libations as prescribed. Thus the ceremony is completed.—27-33.
