As soon as he has performed the Samishtayagus offerings, when the coals are only just extinguished, he takes that embryo with the cloth, and standing with his face to the east, he offers it with a verse to the Maruts (Vâg. S. VIII, 31; Rig-veda I. 86, 1),--'Verily, O Maruts, in whosesoever house ye drink, the heroes of the sky, he is the best protected man.' He utters no Svâhâ (hail), for the Maruts, the clans of the gods are no oblation-eaters, and no oblation, as it were, is what is offered without Svâhâ. And the Maruts are of the gods: he thus establishes it with the Maruts.
