Britannica’s article by renowned religious historian Mircea Eliade on Shamanism states:
“…shaman, a person believed to achieve various powers through trance or ecstatic religious experience. Although shamans’ repertoires vary from one culture to the next, they are typically thought to have the ability to heal the sick, to communicate with the otherworld, and often to escort the souls of the dead to that otherworld.
“As its etymology implies, the term applies in the strictest sense only to the religious systems and phenomena of the peoples of northern Asia and the Ural-Altaic, such as the Khanty and Mansi, Samoyed, Tungus, Yukaghir, Chukchi, and Koryak. However, shamanism is also used more generally to describe indigenous groups in which roles such as healer, religious leader, counselor, and councillor are combined. In this sense, shamans are particularly common among other Arctic peoples, American Indians, Australian Aborigines, and those African groups, such as the San, that retained their traditional cultures well into the 20th century.”
