He need only lay down the Punaskiti; for this is a repeated sacrifice (punar-yagña), it is a later (higher) worship of the gods: it is thus a repeated sacrifice and the higher worship of the gods he thereby arranges, and the repeated sacrifice inclines to him!--so (they say), but let him not do this, for, indeed, whenever Agni is placed on the built (altar), this whole Agni passes into that very brick: thus whenever he offers in the fire, then these oblations of his will be offered even as would be his oblations, when offered on a complete Sândila fire-altar built up with wings and tail.
