Light cannot be seen; it can only be known. Light is still. The sense of sight cannot respond to stillness. That which the eyes “feel” and believe to be Light is but wave motion simulating the idea of Light. Like all things else in this electric wave universe the idea of Light cannot be produced. Electric waves simulate idea only. They do not become idea.
When man sees the light of the sun he believes that he is actually seeing light when the nerves of his eyes are but “feeling” the intense, rapid, shortwave vibrations of the kind of wave motion which he senses as incandescence. The intensely vibrant electric current mirrored into the senses of the eyes fairly burns them. They cannot stand that high rate of vibration. The eyes would be destroyed by such a vibration, but light would not be the cause of that destruction. Fast motion, simulating light, would be the cause. It would be like sending a high voltage electric current over a wire so fine that the current would burn it out.
Man likewise cannot see darkness. The nerves of his eyes which sense motion slow down to a rate of vibration which he can no longer “feel.”
Man is so accustomed to the idea that he actually sees light in various intensities illuminating various substances to greater or lesser degree that it is difficult for him to realize that his own senses are but acting as mirrors to reflect various intensities of wave motion. But that is all that is happening.
Every electrically conditioned thing in Nature reflects the vibrations of every other thing, to fulfill its desire to synchronize its vibrations with every other thing All matter is the motion of light. All motion is expressed in waves. All light waves are mirrors which reflect each other’s condition unto the farthermost star.
This is an electrically conditioned wave universe. All wave conditions are forever seeking oneness. For this reason all sensation responds to all other sensation.
