Orth.—The soul does not crave for food. How could it when it is immortal? But the body, which derives its vital force from the soul, feels its need, and desires to receive what is lacking. So after toil it longs for rest, after waking for sleep, and so with the rest of its desires. So forthwith after its dissolution, since it has no longer its vital energy, it does not even crave for what is lacking, and, ceasing to receive it, it undergoes corruption.
