Thanks Schmidtalex, I think there is something definitely here to consider in the unity of opposites, the yin and yang, the emptiness and form, etc. But I have to admit I am really struggling with that concept because to my Western rational mind, opposites are opposites and cannot be the same. One is one and two is two, not one is also two. I am also working through the whole concept of emptiness in Eastern thought, trying to understand it better because of the contradictions that seem inherent in any definition. I suppose what I am missing is that this idea is really more about experience, about a deep sense of unity despite the contradictions apprehended not so much through intellect as through direct conscious experience. And that gets closer to the mystics and their "discoveries" which now seem to coincide so neatly with today's science.
