The human body represents the five elements, and nature's law is that every element returns to its own origin. Naturally therefore the being which is the air part turns into air, the heat is absorbed by the heat -- the fire-element has left already. The body belongs either to earth or to water. But the body, which is born on earth, not in the water, and has sought its comfort on earth, not in water, and has also been afraid of the water, an element foreign to it, had better be saved from it and had better be buried.
