Hi there, glad you found us. The short answer is no. If a purportedly Indian person is offering to teach 'shamanism' in the UK, or anywhere for that matter, don't just walk away, run away. They will rip you off or otherwise abuse you, no matter how 'spiritual' they seem. Indian spiritual leaders (not sure if that's a good term) serve their communities: they do not cross the Atlantic to make money off gullible Europeans. Tell your friends, before one of them is molested or dies in a fake sweatlodge.
Some Indian people do come to the UK to teach, but not the noble-savage fantasy stuff. Our own Al Carroll is one (he's a historian). In fact Al spoke in Whitstable this time last year, at the arts centre, thanks to our friend Elija van den Berg. Another is
Scott Frazier. If you look at that page you won't see anything there about totems, power animals, vision quests, how to build a sweatlodge, etc.
