holger kalweit had some really good stuff to say about the animist and shamanic perspective on inside and out in his book shamanshealers and medicine men and his other book dream time and inner space. really good books if you can find them maybe the best out there on the subject of shamanism. the inside and out side are just a strange notion, based on improper thinking. in an ecstatic states all boundries are disolved there is no other, or out side or inside its all becomes just oneness. inside and out side are in thier true nature just one thing or one however you want to look at it.
i used to feel that the healing came from out side of me. them i realized the healing came from inside of me, then i realized that it was both and niether, almost...unspeakable... i think that when you in that experince then miracles can happen. the supernatural becomes natural, an all is one.
