YV 5.2h

Verily one wins the gods with the first, power with the second; verily one conquers the world of the gods [3] with the first; the world of men with the second; he performs several forms of sacrifice. This offering is called 'the friendly'; for him there is in this world prosperity on whom the moon rises in the west after he hag sacrificed on that day. He who desires heaven should sacrifice with the Daksayana sacrifice. On the full moon he should offer the Samnayya; on the new moon he should sacrifice with clotted curds for Mitra and Varuna. On the full moon (the Soma) is pressed for the gods; during this half-month it is pressed forth for them, and a cow for Mitra and Varuna is to be slaughtered for them at the new moon. In that [4] he sacrifices on the day before, he makes the sacrificial enclosure. In that he drives away the calves, he metes out the seat and the oblation holder. In that he sacrifices, he produces with the gods the pressing day. He drinks for the half-month Soma in carouse with the gods. In that he sacrifices at the new moon with clotted curds for Mitra and Varuna, the cow which is slaughtered for the gods becomes his also. He mounts upon the gods in truth who mounts upon their sacrifice [5]. Just as a great man who has attained (fortune) desires (and does), so he does. If he misses the mark he becomes worse; if he does not, he remains the same. One who desires distinction should sacrifice with it, for this sacrifice has a razor edge, and swiftly he becomes holy or perishes. His vow is: he shall not speak untruth; be shall not eat meat; he shall not approach for all a woman; they shall not clean his raiment with cleansing stuff; for all these things the gods do not do. The new and the full moon (sacrifices) are the chariot of the gods. He, who having offered the new and the full moon (sacrifices) Sacrifices with Soma, rests in the chosen resting-place of the gods which is conspicuous for its chariot (tracks).
