This is the second idea, yet this is not sufficient; there will be still more doubts. It is very good to say that there is no destruction for any force. But all the forces and forms that we see are combinations. This form before us is a composition of several component parts, and so every force that we see is similarly composite. If you take the scientific idea of force, and call it the sum total, the resultant of several forces, what becomes of your individuality? Everything that is a compound must sooner or later go back to its component parts. Whatever in this universe is the result of the combination of matter or force must sooner or later go back to its components. Whatever is the result of certain causes must die, must be destroyed. It gets broken up, dispersed, and resolved back into its components. Soul is not a force; neither is it thought. It is the manufacturer of thought, but not thought itself; it is the manufacturer of the body, but not the body. Why so? We see that the body cannot be the soul. Why not? Because it is not intelligent. A corpse is not intelligent, nor a piece of meat in a butcher's shop. What do we mean by intelligence? Reactive power. We want to go a little more deeply into this. Here is a pitcher; I see it. How? Rays of light from the pitcher enter my eyes, and make a picture in my retina, which is carried to the brain. Yet there is no vision.
