v. 5. 4.

The waters were the wives of Varuna; Agni longed for them, he had union with them; his seed fell away, it became this (earth); what second fell away became yonder (sky); this is the Viraj, yonder the Svaraj; in that he puts down two Viraj (bricks) he puts down these two (worlds). Now the seed which yonder (sky) impregnates, finds support in this (earth), it is propagated, it becomes plants [1] and shoots; them the fire eats. He who knows thus is propagated, and becomes an eater of food. If a man be full of seed, one should put both down in the first layer for him; verily these in accord pour seed for him; if a man have poured his seed, he should put one in the first layer for him and one in the last; verily he encloses by the two (worlds) the seed he has impregnated. For a year to no man [2] should he descend in honour; for these two (worlds) descend in honour for no man; that is their rule. He who piles the fire without a head, becomes headless in yonder world, he who piles it with a head becomes possessed of a head in yonder world. 'To thought I offer with mind, with ghee, that the gods may come hither, delighting in the offerings, increasing holy order; on the path of the moving ocean I offer all the days to Viçvakarman the undying oblation', (with these words) he puts down the naturally perforated brick and offers [3]; that is the head of the fire; verily he piles the fire with its head. He becomes possessed of a head in yonder world who know thus. The fire is piled for the world of heaven; whatever is done out of order, that is not heavenly; the fire is heavenly; having put down the layer he should stroke it, (saying), 'May the wise discern wisdom and folly, like backs straight and crooked, like men; for wealth and good offspring, O god, grant us freedom, and keep bondage from us.' Verily he puts it down in order. He piles (the fire) facing east; it becomes heavenly for him.
