YV 3.7b

The theologians say, 'By the first day of the twelve-day rite what is it that the sacrificer takes from the priests?' 'Brilliance and power' is (the answer). 'What by the second?' 'The breaths and food.' 'What by the third?' 'These three worlds.' 'What by the fourth?' 'Four-footed cattle.' 'What by the fifth?' 'The Pankti with its elements.' 'What by the sixth?' 'The six seasons.' 'What by the seventh?' 'The Çakvari with its seven feet.' 'What by the eighth?' 'The Gayatri with its eight syllables.' 'What by the ninth?' 'The Trivrt Stoma.' 'What by the tenth?' 'The Viraj with its ten syllables.' 'What by the eleventh?' 'The Tristubh with its eleven syllables.' 'What by the twelfth?' 'The Jagati with its twelve syllables.' So much is there as that. So much as that he takes from them. (The rite) of thirteen nights is a complete (rite of) twelve days, for the opening and concluding days are the same. There are three Atiratras, three are these worlds, for the obtaining of these worlds. The first Atiratra is the expiration, the second cross- breathing, the third inspiration; verily they find support in expiration, inspiration, out-breathing, and food, and reach their full life, who knowing thus perform (the rite) of thirteen nights. They say, '(The rite) of twelve days is the sequence of speech. They would cleave it if they put an Atiratra in the middle, and the speech of the householder would be liable to fail.' They perform the Mahavrata after the Chandomas; verily they maintain the sequence of speech, and the speech of the householder is not likely to fail. The Chandomas are cattle, the Mahavrata food; in that they perform the Mahavrata after the Chandomas, they find support in cattle and in food. The Adityas desired, 'May we be prosperous in both worlds.' They saw this (rite) of fourteen nights; they grasped it, and sacrificed with it. Then indeed they prospered in both worlds, this and yonder.
