The physical body cannot exist without food, and therefore in an indirect sense they are one and the same. The body assimilates that portion of the food which is useful for its maintenance, and throws out that portion which is useless. That which is discarded is as much part of the food that was consumed as that which is assimilated. If man is so supremely indifferent to the eliminated refuse, why should he not feel the same detachment towards the assimilated food which, for practical purposes, becomes his body? Why should he shed tears when, after death, the body itself is cast off to the care of earthworms or to consuming flames?
