YV 3.5g

'Thou art the portion of the Yavas', (with these words he puts down) on the south; the Yavas' are the months, the Ayavas are the half-months; therefore the months turn to the south; the Yavas are food, offspring is food; verily he places food on the south; therefore with the right food is eaten. 'Thou art the portion of the Rbhus', (with these words he puts down) on the west, for support. 'The revolving, the forty-eightfold', (with these words he puts down) on the north, to confer strength on these two worlds; therefore these two worlds are of even strength [5]. He becomes first for whom these are placed on the east as the beginning (of the sacrifice), and his son is born to be first; he eats food for whom on the south these (are placed) rich in food, and a son is born to him to eat food; he finds support for whom these (are placed) on the west, full of support; he becomes forcible for whom these (are placed) on the north, full of force, and a forcible son is born to him. The fire is a hymn; I verily in that this arrangement [6] is made are its Stotra and Çastra produced; verily in the hymn the Arkya (Saman and Çastra) is produced; he eats food, and his son is born to eat food, for whom this arrangement is made, and he too who knows it thus. He puts down the creating (bricks); verily he wins things as created. Now there was neither day nor night in the world, but it was undiscriminated; the gods saw these dawn (bricks), they put them down; then did this shine forth; for him for whom these are put down the dawn breaks; verily he smites away the dark. 'O Agni, drive away those foes of ours that are born', (with these words) he puts down on the east; verily he drives away his foes on birth. 'That are born with force', (with these words he puts down) on the west; verily he repels those that are to be born.
