History of Siberian shamanism
According to archeology, shamanic rituals were practiced in Siberia in the Neolithic and bronze age. Unlike most religious teachings, created a particular founder, shamanism was a natural, historical way.
At a certain stage of reflection of the world in the minds of people, the image of the mythical Universe became so significant and developed that only persons with special abilities and special training could understand it. In most societies, there is a need for a "mediator" between the human and the other worlds.
One of the most ancient shamanistic burials in Russia was found on the deer island near lake Onega and apparently belongs to the Mesolithic period, numbering 6 thousand years.
