"Hawaiian Shamanism"

I'm becoming increasingly worried about the issue of cultural appropriation as it relates to my use of the Huna system. I've never maintained that Huna is an authentically Hawaiian system, but it does make that claim. I really don't have enough evidence either way yet to form my own opinion. I've seen some natives denounce Serge King and Max Long and yet recommend books by Deepak Chopra and charge for their own services (which often sound very similar to what I know of King's practices). I've also seen some natives which seem to support King and Long. I, admittedly, just don't know enough of the mythology and religious traditions of Hawaii to know what is bunk and what is not. I currently use King's version of Huna because the principles it espouses make sense to me and I have seen practical results from it. I'm very open to adjusting my practices as I learn more about the traditions it may be based on, or at least has adopted as a backdrop. To that end, I'm archiving this bookmark as a place to start further seeking:
