Welcome, Ardal.
One good fraud detector is their advertising a mix of various different ethnic traditions, plus various Newage practices.
Nuage stuff: spiritualism, theosophy, Tarot, crystals, Reiki, Pranic Healing.
Theosophy is particularly interesting as it is based on a theory of so-called root races which declares ndns to be a senile race prone to extinction. (Theosophy has also been discussed in several threads in this forum.)
Then she claims to have studied „gypsy philosophy“. Any person with real contacts to Roma and/or Sinti will be aware that, for the majority of them, „gypsy“ is a no-go. Roma and Sinti also do not pass their traditions to outsiders.
Another fraud detector is persons claiming one nation and teaching spirituality of one or several other nations.
Cotten claims „Cherokee“ without being any more precise. Usually, members of an indigenous nation can and will name their family, clan or band, relatives etc., and with more detail than just a „cousin Bobcat“.
A „Council of Elders and Medicine Man“ (just one of them? ? ?) ? And for/from which nation? A google search for that only produces her facebook site and the website advertising the event. A search for „... medicine men“ is not particularly successful either.
Why would a Cherokee teach Lakota spirituality? Whenenver you see persons claiming this, you can bet they are plastic shamans, usually of non-indigenous descent, or of very distant indigenous descent.
