Everything that is part of perception shows us what is going on in the mind. No matter what you are looking at, these are symbols that are part of the perceptual world. When we allow these symbols to be used there is a free flow, not unlike that of a river. The goal is to come to an experience that there is nothing outside you. Not the you you think you are, but the You in a Spirit sense. Ultimately the experience of seeing yourself as an Idea in the mind of God is what one lives.
