'O Agni, thousand-eyed!--through the chips of gold Agni is indeed thousand-eyed;--hundred-headed,'--inasmuch as, at that time, he was created as the hundred-headed Rudra;--'thine are a hundred out-breathings, and a thousand through-breathings,'--his indeed are a hundred out-breathings and a thousand through-breathings who is hundred-headed and thousand-eyed;--'thou art the master of wealth,'--that is, 'thou art the master of all wealth;'--'to thee, our strength, do we give honour!'--he (Agni) is indeed the strength: it is him he thereby gratifies.
