SHAMANISM is understood by some people to be a primitive form of religion or religio-magic practised by the aborigines of northern Asia as well as by all other aborigines in other parts of the world. This opinion is held by Mikhailowski, Kharuzin, and some other Russian scientists. Others hold that Shamanism was only one form of expression of the religious cult of northern Asia, practised in order to avert the evil spirits. This opinion is found in the writings of Jochelson and Bogoras. There is still another view put forward, which it is well for us to consider. This view we find expressed very clearly in the following extract from Klementz: 'One must not lose sight of the fact that in the various beliefs of the Siberian tribes a very close connexion is noticeable, and, likewise, there can be observed an uninterrupted identity in the foundations of their mythology, and in their rites, even extending as far as the nomenclature-all of which gives one the right to suppose that these beliefs are the result of the joint work of the intellectual activity of the whole north of Asia.'
