Well a "real" natural born shaman is probably not selling seminars on the internet
But some of them are very interesting seminars and are in vacation locations such as Bali, and Hawaii so there is some vacation quality to the seminar
Shaman's that are born into a tribal culture are not as plentiful as they once were because the process called democracy have homogenized and blended a "smoothie" culture.
O/T I have a son on the Kona side of the big Island. Very few Haouli's are allowed or invited into the Huna tradition but one can be invited.
There are seminars but that is not quite like living in a geographical location, in this case, Hawaii and being accepted by the local healers and being invited into the ceremonies and the actual community or tribe.
