The beauty of the whole creation is this, that creation has worked in two ways; in one way it has expressed, and in the other way it has made itself a mold in order to respond. For instance, there is substance - matter to touch - and there is a sense to feel touch. There is a sound, and at the same time there is the sense of hearing to perceive the sound. There is light, there is form, there are colors, and at the same time there are eyes to see them.
