I hope you enjoy the discussions here.
I read your new web site and would question a few comments.
# Ordinary people can't become shamans through their own efforts. People who subsequently become shamans are traditionally "chosen" by the spirit world through an involuntary initiation experience frequently occuring in their late adolesence.
# Initiation entails real physical death or full blown "near death experience"
# The initiate passes to the spirit world through a "rainbow door" or "rainbow bridge" the experience of which shatters the soul to be subsequently reassembled (in some meaningfully different way) upon return to the physical body and "this" world.
# Initiates undergo a lengthy and painful period of adjustment during which they struggle to balance both worlds in terms of their own unique experience. Those who succeed become shamans able to utilize their capacities usefully while those who fail to integrate them tend to go insane and/or die young
Not all cultures or 'shamanic' healers go through what you have written. Perhaps the above was your psychedelic experience but others may (and do) vary! These tired, elitist, badge of honour style requirements listed in so many books have little to do with the real world service to others, to the Universe or a person's ability to communicate with the spirits. The spirits seem to approach us and choose us in different ways. The label 'shaman' is perhaps the least important aspect of all.
