YV 5.2f

The theologians say, 'He would indeed offer the new and full moon (sacrifices) who should offer them with Indra.' At the full moon there is the subsequent offering of the enemy-dispelling (oblation), and by it the full moon has Indra. There are curds for Indra at the new moon; verily the new moon has Indra. He who knowing thus offers,' the new and full moon sacrifices, offers them with Indra, and day after day it becomes better for him who has so sacrificed. What the gods did at the sacrifice, the Asuras did. The gods [1] saw this offering, one on eleven potsherds for Agni and Visnu, an oblation for Sarasvati, an oblation for Sarasvant; after performing the full moon (sacrifice) they offered this. Then the gods prospered, the Asuras were defeated. He who has enemies should offer this offering after performing the full moon (sacrifice). With the full moon (sacrifice) he hurls the bolt at his enemy, with (the offering) to Agni and Visnu he appropriates the gods and the sacrifice of his enemy, his pairing cattle with (the offerings) to Sarasvati and Sarasvant. Whatever he has, all that [2] he appropriates. One should sacrifice at the full moon, if one has enemies, not at the new moon; having slain one's enemy one does not cause him to grow again. He who desires cattle should sacrifice with the Sakamprasthayiya. The man to whom they bring (any thing) in small measure is not himself pleased, and does not give to another. But he, to whom they bring in large measure, is himself pleased, and gives to another. One should offer in full and large measure; Indra then being pleased delights him with offspring and cattle. He offers with a wooden vessel, for an earthenware one does not hold the offering. It is of Udumbara wood [3]; the Udumbara is strength, cattle are strength; verily by strength he wins for him strength and cattle. One should not sacrifice to, Mahendra, if one is not prosperous. The prosperous are three; a learned (Brahman), a village headman, and a warrior.
