The idea for today is an extension of the previous one. You do not think of light in terms of strength, and darkness in terms of weakness. That is because your idea of what seeing means is tied up with the body and its eyes and brain. Thus you believe that you can change what you see by putting little bits of glass before your eyes. This is among the many magical beliefs that come from the conviction you are a body, and the body’s eyes can see.

You also believe the body’s brain can think. If you but understood the nature of thought, you could but laugh at this insane idea. It is as if you thought you held the match that lights the sun and gives it all its warmth; or that you held the world within your hand, securely bound until you let it go. Yet this is no more foolish than to believe the body’s eyes can see; the brain can think.
