'Reverence be to you, the sparkling,' for those (Rudras) produce (kar) everything here,--'hearts of the gods!'--Agni, Vâyu and Âditya (fire, wind and sun), these truly are the hearts of the gods;--'Reverence to the discriminating!'--for those (gods) discriminate everything here;--'Reverence to the destructive!'--for those (gods) destroy whom they wish to destroy;--'Reverence to the irremovable!'--for those (gods) are not (to be) removed from these worlds.
