2.1.4.3

taddhaike 'jamupabadhnanti | āgneyo 'jo 'gnereva sarvatvāyeti vadantastadu tathā na kuryādyadyasyājaḥ syādagnīdha evainam prātardadyāttenaiva taṃ kāmamāpnoti tasmādu tannādriyeta

Here now some tie up a he-goat, arguing that the goat is sacred to Agni and that (this is done) for the completeness of the fire. But he need not do this. Should he possess a he-goat, let him present it to the Âgnîdhra on the next morning; for it is thereby that he obtains the object he desires. He need, therefore, take no notice of that (practice).
