YV 5.7c

Whether by faith, or by lack of faith-that is, those which have no horns-both indeed were prosperous, those which gained horns and those which won strength. He who ceases after ten months is prosperous, and he who ceases after twelve also, if he knows thus. They go by their feet, and he who goes by his foot attains (what he seeks). The Ayana is successful, and therefore is it productive They perform the Prahas in the first month, they perform them in the middle month, they perform them in the last month. They say, 'In the case of a cow which they milk thrice a day, she yields sparingly at the latter two milkings; how then can she be milked who is twelve times milked?' Having made up the year, they should perform the Prsthas once in the last month; verily the sacrificers win the sacrifice and cattle. It is an ocean [1] without a near or a further shore that they enter upon who perform the year (rite). If they employ the Brhat and the Rathantara Samans, it would be as if they were to provide a boat in the middle of the ocean. Going continuously with the Brhat and the Rathantara they obtain support. The union is milked for all desires; thus the sacrificers obtain all desires. The Rcs are the same. The Rcs are the world of men; verily they leave not the world of man. There are different Samans; the Saman is the world of the gods; verily they descend from the world of the gods to one world after another of men. They first use the Jagati, and the metres descend from the Jagati, the cups from the Agrayana, the Prsthas from the Brhat, the Stomas from the Trayastrinça. Therefore the younger descends before an elder. The Viçvakarman cup is drawn; verily by it the sacrificers win all rites. The cup for Aditi [1] is drawn. Aditi is this (earth); verily they rest on this (earth). The one and the other are drawn, for pairing, for propagation.
