Malfoyish, Beowulf, deafdyke and Mitcham,
Gotcha. I understand what you mean. I also didn't share my spiritual experience with the public too because of "devil" comments like what you said in your post. Apparently that it is much easier for me to shut up than speaking up in the public and deal with close-mindedness. I am not implying that AD'ers are close-minded people and all, I never say that. Just implying that I noticed that some of christians would say that to me whenever I bring up about it.
I want to discuss a bit more about this:
Shaman could not do this because they are not God. They have to ask first before they can do the healings.
According to my knowledge that they (shamans) never claim that they are 'God'. But I am not sure if they do or do not ask before they can do the healing. I don't know how much you know about Native American culture but most of these tribes tend to kneel and give their thanks to Creator (God) whenever they slay the animals for survival reasons. There is much more about these Native American and their wonderful spirituality belief. I am glad that you decide to share your view with us
