A reader asked me to be more specific about Olga Kharitidi and her shamanic experiences in the Altai. Here you go:
Olga Kharitidi is a psychiatrist from Novosibirsk, a big city in Siberia. In the early nineties Kharitidi visited the Altai, where she learned about shamanic healing practices from a local female shaman called Umai. At least, that is what Olga Kharitidi claims.
