"Yeah, our view of reality, the one we conventionally take, is one among many. It’s pretty much a fact that our entire universe is a mental construct. We don’t actually deal with reality directly. We simply compose a picture of reality from what’s going on in our retinas, in the timpani of our ears, and in our nerve endings. We perceive our own perception, and that perception is to us the entirety of the universe. I believe magic is, on one level, the willful attempt to alter those perceptions. Using your metaphor of an aperture, you would be widening that window or changing the angle consciously, and seeing what new vistas it affords you."
