In plain words
And it is said elsewhere too: This food is the body of the blessed Viṣṇu named the World-bearer. The breath is the savour of food, the mind of the breath, understanding of the mind, and bliss of understanding. He who knows thus comes to have food, breath, mind, understanding and bliss. And as many beings here eat food, so many does he, standing within them, eat as food, who knows thus. "Food is what keeps off old age; food is called what wins others over; food is the breath of cattle; food is the eldest, and food is called the healer."
