The marriage of the sun and moon Book

I'd read The Natural Mind years before, liked it, remembered it enough to notice and pick up this subsequent work by Dr. Weil about altered states of consciousness. Unlike the former book, this is a collection of essays ranging from discussions of class-one narcotics to pieces praising tropical fruits and hot--very hot!--peppers. (The pepper article really raised my eyebrows, but I'm not ready for that path of self-transcendence yet). Weil is a very engaging writer, the kind of person one would want as a family physician and, judging by his oeuvre, health guru. He looks, with his bearded teddy-bear visage, like Ginsberg and is just about as non-threatening. His advocacy of certain natural psychotropics is quite sincere, careful and discriminating.
