He thought, 'If I kill him, I shall have but little food.' He therefore brought forth by that speech and by that body (the year) all whatsoever exists, the Rik, the Yagus, the Saman, the metres, the sacrifices, men, and animals. And whatever he (Death) brought forth, that he resolved to eat (ad). Verily because he eats everything, therefore is Aditi (Death) called Aditi. He who thus knows why Aditi is called Aditi, becomes an eater of everything, and everything becomes his food.

In plain words: Death thought that if he ate the child he would have little food, so instead he created everything—the sacred hymns, rituals, people and animals—and set out to eat it all. That is why he is called Aditi, from the word 'to eat,' and whoever knows this can enjoy everything.
