YV 6.7j

The gods drew the cups in a line; Prajapati saw this Ançu, drew it, and therewith prospered. Verily he, for whom knowing thus the Ançu is drawn, prospers. He draws from (the Soma) when it has been once pressed, for once he prospered thereby. He draws with the mind, for Prajapati is mind as it were; (verily it serves) to obtain Prajapati. He draws with (a vessel) of Udumbara; the Udumbara is strength; verily he wins strength; it has four corners; verily he finds support in the quarters [1]. He who knows the foundation of the Ançu becomes possessed of a foundation. The Saman is that called the Vamadevya; singing in his mind that foundation he draws; verily he becomes possessed of a foundation. If the Adhvaryu were not to make a success of drawing the Ançu, for both the Adhvaryu and the sacrificer would it go ill; if he were to make a success, for both would it go well; he draws without breathing; this is its success. He breathes over gold; gold is immortality, breath is life; verily with life he quickens immortality; it is of a hundred (Krsnalas) in weight, man has a hundred (years of) life, a hundred powers; verily in life, in power he finds support. Prajapati assigned the sacrifices to the gods; he thought himself emptied; he pressed over himself the power and strength of the sacrifice in sixteen ways; that became the Sodaçin; there is no sacrifice called Sodaçin; in that there is a sixteenth Stotra and a sixteenth Çastra, therefore is it the Sodaçin, and that is why the Sodaçin has its name. In that the Sodaçin is drawn, so the sacrificer bestows power and strength upon himself. To the gods the world of heaven [1] did not become manifest; they saw this Sodaçin, and drew it; then did the world of heaven become manifest to them; in that the Sodaçin is drawn, (it serves) for the conquest of the world of heaven.
