He who piles up the fire falls away from this world; his libation cannot be performed in a place without bricks; whatever libation he offers in a place without bricks, it runs away, and with its running away the sacrifice is ruined, with the sacrifice the sacrificer; in that he piles up a second piling, (it is) to support the libations; the libations find support [3], the sacrifice is not ruined, nor the sacrificer. He puts down eight; the Gayatri has eight syllables; verily he piles it with the Gayatri metre; if eleven, with the Tristubh, if twelve with the Jagati verily he piles it with the metres. The fire that is re-piled is called the descendant; he who knowing thus re-piles the fire eats food up to the third generation. The re-piling is like the re-establishment of the fire; he who does not succeed through the establishment of the fire [4] re-establishes it; he who does not succeed by the piling up of the fire re-piles it. In that he piles up the fire, (it is) for prosperity. Or rather they say, 'one should not pile it up.' The fire is Rudra, and it is as if one stirs up a sleeping lion. But again they say, 'One should pile it up.' It is as if one awakens a richer man with his due portion. Manu piled the fire; with it he did not prosper; he saw this re-piling, he piled it, with it he prospered; in that he piles the re-piling, (it is) for prosperity. He who desires cattle should pile a piling with the metres; the metres are cattle; verily he becomes rich in cattle. He should pile in hawk shape who desires the sky; the hawk is the best flier among birds; verily becoming a hawk he flies to the world of heaven. He should pile in heron form who desires, 'May I be possessed of a head in yonder world'; verily he becomes possessed of a head in yonder world. He should pile in the form of an Alaja bird, with four furrows, who desires support; there are four quarters; verily he finds support in the quarters.
