These pregnant words are the key to the religion of the Siberian natives, and afford the only intelligible explanation of the origin of shamans. If any proof were needed that this system of religion is the natural outgrowth of human nature in certain conditions of barbarism, it would be furnished by the universal prevalence of Shamanism in north-eastern Siberia among so many diverse tribes of different character and different origin. The tribe of Tunguses for instance, is certainly of Chinese descent, and the tribe of Yakuts is certainly Turkish. Both came from different regions, bringing different beliefs, superstitions, and modes of thought; but, when both were removed from all disturbing agencies and subjected to the same external influences, both developed precisely the same system of religious belief. If a band of ignorant, barbarous Mahometans were transported to north-eastern Siberia, and compelled to live alone in tents, century after century, amid the wild, gloomy scenery of the Stanavoi Mountains, to suffer terrific storms whose causes they could not explain, to lose their reindeer suddenly by an epidemic disease which defied human remedies, to be frightened by magnificent auroras that set the whole universe in a blaze, and decimated by pestilences whose nature they could not understand and whose disastrous effects they were powerless to avert—they would almost inevitably lose by degrees their faith in Allah and Mahomet, and become precisely such Shamanists as the Siberian Koraks and Chukchis are today. Even a whole century of partial civilisation and Christian training cannot wholly counteract the irresistible Shamanistic influence which is exerted upon the mind by the wilder, more terrible manifestations of Nature in these lonely and inhospitable regions. The Kamchadals who accompanied me to the Samanka Mountains were the sons of Christian parents, and had been brought up from infancy in the Greek Church; they were firm believers in the Divine atonement and in Divine providence, and prayed always night and morning for safety and preservation; yet, when overtaken by a storm in that gloomy range of mountains, the sense of the supernatural overcame their religious convictions, God seemed far away while evil spirits were near and active, and they sacrificed a dog, like very pagans, to propitiate the diabolical wrath of which the storm was an evidence.
