YV 1.7a

The One Day Sacrifices Production of offspring is light. Agni is the light of the gods; the Viraj is the light of the metres. The Viraj of speech ends in Agni; it is produced according to the Viraj. Therefore it is called light. Two Stomas bear the morning pressing, like expiration and inspiration; two the midday pressing, like eye and ear; two the third pressing, like speech and support. This sacrifice is commensurate with man, and is perfect [1]. Whatever desire a man has, he wins by it, for one wins all by that which is perfect. By means of the Agnistoma Prajapati created off spring; by means of the Agnistoma he grasped them. When he grasped them the mule escaped. Following it he took its seed, and placed it in the ass. Therefore the ass has double seed. They also say, 'He placed it in the mare.' Therefore the mare has double seed. They also say, 'In the plants [2] he placed it.' Therefore plants, though not anointed, glisten.' They also say, 'He placed it in offspring.' Therefore twins are born. Therefore the mule has no offspring, for his seed has been taken from him. Therefore he is not suitable for the sacrifice, but is suitable if there is a sacrifice when one gives (to the priests) all one's goods or a thousand, for he escaped. He who knowing thus sacrifices with the Agnistoma begets unborn offspring and grasps those that are born. Therefore they say, 'It is the best of sacrifices [3].' Prajapati indeed is the best, for he sacrificed with it first. Prajapati desired, 'May I have offspring.' He meted out the Trivrt from his mouth. After it the god Agni was created, the Gayatri metre, the Rathantara Saman, of men the Brahman, of cattle the goat; therefore are they the chief, for they were produced from the mouth. From the breast and arms he meted out the Pañcadaça Stoma. After it the god Indra was created, the Tristubh metre, the Brhat [4] Saman, of men the Rajanya, of cattle the sheep. There fore they are strong, for they were created from strength.
