Aldous Huxley "The Doors of Perception" "Heaven and Hell"

I think that Huxley's idea of the mystic functioning beyond the realm of opposites is not a new idea. It has been discovered by Mystics throughout history of man. This consciousness beyond the realm of opposites is the same as the resolution of opposites graphically represented by the Circle or the enyo in Japanese or the Ouroboros, which is the snake with its tail in its mouth. This Ouroboros or circle is the most fundamental and powerful of religious symbols. The mind can only function in opposites but there is no peace of mind until we realize that everything that we can think of has an interdependent opposite; they both arise simultaneously. So if you have a god destroying the devil, then the god must disappear also.

So every religion has its basis in mysticism. Heinrich Zimmer said, "The most important thing [religious experience] cannot be talked about. The second most important thing refers to that first thing [in metaphor] and is always misunderstood." Therefore all organized religions have their basis in this misunderstanding. So the mystics of any particular religion have more in common with the mystics of any other religion than the fundamentalists of their own religion.
