Hi 4Bears,
What an excellent question! I can only give you my take on this, which is similar to Kathryn's--call the practitioners by the words their own people use. I've cut the s-word almost entirely out of my vocabulary because seems both too vague and too specific (Siberian).
To me, a term like "shamanic religions" is, again, too vague to be useful. I like the books of Joseph Campbell too, but IMO he had a tendency to lump everything together to fit his "monomyth," sort of like Fraser seeing dying gods everywhere he looked and Harner deciding all "shamans" do the same things, make the same journeys to the same places, etc.
If we mean people who work with the spirits or gods directly, is it proper/accurate to call them "visionaries" or "mystics," or does that only make things more confusing?
I hope someone else will weigh in on this? Or, if it ought to be on another thread, I apologize for going O/T.
