"All the metres are to be recited in this sacrifice," they say; the Kakubh is the strength of the Tristubh, the Ushnih of the Jagati; in that he repeats the Ushnih and the Kakubh, thereby he wins all the metres. The Ushnih is the Gayatri; the four syllables over are four-footed cattle; just as cake is over cake, so it is with the syllables which are over the verse; if he were to close with a Jagati, he would end the sacrifice; he closes with a Tristubh, the Tristubh is power and strength; thus he establishes the sacrifice on power and strength, and does not end it. "O Radiant One, three are thy strengths, three thy abodes," with this verse containing the word "three" he closes, for similarity of form: that which has three constituents is the whole of the sacrifice; for every desire it is employed, for the sacrifice is employed for all desires. With the same offering should he sacrifice who is going to sacrifice with a thousand; thus he produces and gives it. One who has sacrificed with a thousand should sacrifice with the same offering; he goes to the end of cattle who sacrifices with a thousand; the Creator created cattle; He created them with the offering of three constituents; one who, knowing thus, sacrifices, desirous of cattle, with the offering of three constituents, creates cattle from the very source whence the Creator created them; and the thousand resorts to him. He who, having said, "I shall sacrifice," does not sacrifice, becomes a prey to want; he should sacrifice with the offering of three constituents; the offering of three constituents is the whole of the sacrifice; thus he sacrifices with the whole of the sacrifice. The cake is on twelve potsherds; these are three sets of four potsherds, to bring about the three. There are three cakes, these worlds are three; they serve to win these worlds. Each one above the other is larger, for so as it were are these worlds. The middle one is made of barley, that is the form of the atmosphere; it serves for prosperity. He cuts off from all the cakes as he sets them up without making a failure. He gives gold; thus he wins brilliance; he gives the silken garment; thus he wins cattle; he gives a cow; thus he wins his prayers; gold is the colour of the Saman, the silken garment of the formulae, the cow of the praises and rejoicings; thus he wins all these colours.
