Whether or not Shannon Parsons and Tim Yearington have a bit of distant heritage, it looks like the usual pan-Indian misinformation peddled by nuagers. I don't see any hint of authenticity or cultural connection.
They claim to be teaching '
an ancient, all-encompassing "Aboriginal Wisdom System." ("The acronym we use for this is AWSYM, pronounced "awesome", because it is! It is a power tool.')[sic] As in, throw it all in a blender, mix fragments of misunderstood ceremonies all together and sell it.
Tim Yearington is teaching nuage, pan-NDN/Lakota-lite "medicine wheel" workshops, that have nothing to do with the cultures they claim, and that are inappropriate for the territory where they live.
http://www.medicinepinehealing.ca/medicine-wheel-waysFor them to ask people for $120 to have tea with them, and call this "traditional Native guidance" seem grandiose and exploitative. As they imply they are doing healing for people in these sessions, I'd say this falls under selling ceremony, even if they don't know any real ones to sell.
