Pragâpati produced the sacrifice. His greatness departed from him, and entered the great sacrificial priests. Together with the great priests he went in search of it, and together with the great priests he found it: when the great priests eat the priests’ mess of rice, the Sacrificer thereby secures for himself the greatness of the sacrifice. Along with the priests’ mess of rice he presents gold (to the priests); for the mess of rice is seed, and gold is seed: by means of seed he thus lays seed into that (horse, and Sacrificer). It (the gold) weighs a hundred (grains); for man has a life of a hundred (years), and a hundred energies: it is life, and energy, vigour, he lays into his own self. At midday he takes Vasatîvarî water of four kinds; it is brought together from the (four) quarters, for food is in (all) the (four) quarters, and water is food: by means of food he thus secures food for him.
