There is a well-known fact that goes entirely ignored: the mind and the body are the same thing. (Keep looking for the soul, it must be around here somewhere.) Organic matters are the matter of thought; this is difficult to imagine because trees seem so explicable when cut down, but brains are less obvious. I don't take the mystic traditions at their word; the energy between brain and tree, I'll believe when it can be observed. But, I do find it off to forget that blood is necessary for a brain is necessary for thoughts which require fuel which trees seem happy to provide. Living next to each other, our bond in space and time cannot be so easily denied.
