Hi sara(h)ng. When a belief has been tooling around multiple cultures for millenia, I think there's something to it-that's the case for the notion of chakras & subtle energies. Shoot, Tibetan Buddhsim makes that a core aspect of their spiritual approach as one would expect from a tantric system. What i wasn't aware of was that apparently similar notions could be found in shamanic systems of the americas-if you believe the anthropologist Alberto Villoldo. I've recently become a student of his published work-he has adapted the traditional teachings of Peruvian Inka tradition shamans on the subtle energy systems. think you might find his book, "Shaman, Healer, Sage" particualrly good as he goes into a good bit of detail re the shamans he has studied with as well as the methods of work. Interestingly he posits a 9 chakra system: the eighth he describes as "a few inches above our heads...where we experience a union with all of creation and its Creator" and the ninth as : "exists outside of time and space...where we experience the expanse of creation.This is where we reside within God." He notes exercises for clearing chakras in most of his books such as the aforementioned as well as "The Four Insights." Interesting info on the blending of subtle energy work and shamanic healing. Am about to start his book re soul retrieval. Interesting notions contained in such an approach-the idea of "fragments" of one's soul being essentially left behind in time as a result of traumas & such and reengaging with those fragments as an "enwholing" experience. As I move on in years, being in my 50's, have those hard-to-pin-down moments of ennui-feeling as if I have left parts of my "original self" behind which I am missing in a way. I could stand to become a "wholier" me.

Take care, earl
