"Take a piece of glass, paint colours and forms on it, and put into a magic lantern, turn on a white light, and the colours and forms painted on the glass are reproduced on the screen. If that light were not turned on, you would not see the colours of the slide on the screen.

"So is it with an ordinary man. His mind is like the screen. On it shines the light, dulled and changed because he has allowed the many-sided world to stand in the way of the Light (God). He sees only the effects of Light (God) instead of the Light (God), and his mind reflects the effects he sees just as the screen reflects the colours on the glass. Take away the prism and the colours vanish, absorbed back into the white light from whence they came. Take away the colours from the slide and the light shines clearly through. Take away our sight the world of effects we see, and let us look only into the causes, and we shall see the Light (God)."
