Narkissos,
Yes. France. America. Biiiiiiiig difference!
Winston,
I'm not sure there is even much talk of "spirit" in Zen. I mean, practicers of Zen don't even really believe in reincarnation either. Interestingly, there have been studies done of meditators who talk about "being one" with the universe and it is reported that part of the brain -- the part responsible for location in space -- actually can shut down when they feel this. Now, is that an illusion, much like a psychedelic drug, or is the "real thing"? I'm not about to answer that.
Basically this whole discussion is about monism versus dualism. I would think most Zen people would be classified as monists, but I could be wrong.
