He bethought him, 'Surely, if I kill him, I shall gain but little food.' By that speech and that soul of his he created all this (universe) whatsoever there is,--Rik (hymn-verses), Yagus (formulas), Sâman (hymn-tunes), metres, sacrifices, men, and beasts. And whatsoever he created he set about devouring; and because he eats (ad) everything, hence the name 'Aditi'; and, verily, he who thus knows the nature of Aditi becomes an eater of everything, and all food becomes his.
