YV 2.2f

He whose fire goes out after it has been taken out (from the Garhapatya) before the Agnihotra has been offered should offer a cake on eight potsherds to Agni with light; (they say), 'Should another be taken out, after lighting up (from the Garhapatya)'? That should not be done. Since the former is taken out for a definite share, how should another [7] be taken out for (it)? He should deposit the extinguished embers and produce fire by friction, (with the words), 'Hence first was Agni born, from his own womb, the all-knower; he with Gayatri, Tristubh, Jagati shall bear the oblation to the gods, the wise ones'; with the metres he begets him from his own womb; 'this is the fire', they say, I what falls from it is light'; in that he offers to Agni with light, he wins the light which has fallen from it. He who is calumniated should offer on twelve potsherds to Vaiçvanara, an oblation to Varuna, and an oblation to Dadhikravan; in that there is (an offering) on twelve potsherds to Vaiçvanara, and Agni Vaiçvanara is the year; verily he satisfies him with the year, he smites off the evil hue; by (the offering) to Varuna he frees him from the noose of Varuna; by Dadhikravan he purifies him. The sacrificial fee is gold; gold is a purifier; verily he purifies him; his food becomes fit to eat. The same (offering) he should make who desires offspring; the year [1] unpropitiated burns up the womb of offspring, of cattle, for him who being fit for offspring does not obtain offspring; in that there is (an offering) on twelve potsherds for Vaiçvanara, and Agni Vaiçvanara is the year; verily he propitiates the year with its own share; it propitiated begets offspring for him from his own womb; by (the offering) to Varuna he frees him from the noose of Varuna; by Dadhikravan he purifies him. The sacrificial fee is gold; gold is a purifier; verily he purifies him [2]; he obtains offspring.
