You think some muslim whipping himself is getting an experience equivalent to mushrooms?
I don't think they're comparable in any way whatsoever.
I think that's pretty damn racist... considering it was the Catholic Church that originated that tradition.
I believe all ++++'s are directly related to the kinds of enlightenment that was gained by many religious leaders...
Buddha, gained enlightenment through intense fasting and meditation
Jesus, wandered the desert without food or water for 40 days, and was apparently tempted by the Devil during this time
Muhammad, I believe the Muslims believe he was directly contacted by God during a time he was removed from the world..? I'm not exactly well versed on this religion though, so my apologies if that's wrong.
Point is, many many religious (and non-religious) people over the years have had experiences we could describe as a ++++ that led to their "enlightenment", where their eyes were opened by the "Gods".... this is always repeated through out history, it happens in almost every religion.
I think religious enlightenment, sensory deprivation, out of body experiences, lucid dreams, altered brainwaves that occur when you listen to music, fasting, orgasms, experiences caused by psychedelic drugs or a combination of any of those are all connected...
Each one of those experiences has a direct effect on the neurochemicals that flow through our brain everyday... particularly serotonin. With such commonly repeated experiences that have been taking place in humans since the dawn of time in EXTREMELY different circumstances... there has to be some kind of connection.
Whether you would like to think of it as a chemical one, or a religious one, there is an obvious connection.... I choose to believe that religion is a way of directly altering your neuro-chemistry... but that's just me.
