Let us turn from mystic numbers and decorative designs to another aspect of primitive life. The Turkish tribes of western Siberia have a form of religion based on the belief that certain individuals enjoy the hereditary privilege of acting as intermediaries between their ancestral spirits and the people at large. With the aid of his sacred drum the shaman, as such an intermediary is technically called, is able to summon the supernatural beings, cure the sick, foretell the future, separate his own soul from his body and send it to the upper realms of light or the nether regions of darkness. Now, although a particular individual inherits the shaman’s office from his father, he receives no formal instruction nor does he make any active preparation for his mission. His call comes in the form of a sudden paroxysm. He is seized with a feeling of languor and a fit of violent convulsions, with abnormal yawning, and a powerful pressure on the chest, which causes him to utter inarticulate screams. He begins to shiver with cold, rolls his eyes, suddenly leaps up and madly circles about until he falls down covered with perspiration and writhing in epileptic spasms on the ground. His members are devoid of sensation, his hands grasp without discrimination red-hot iron, knives, pins; he swallows such objects without suffering the slightest injury, and again ejects them from his mouth. Finally, the prospective seer seizes a shaman’s drum and assumes the shaman’s office. Disobedience to the spirit’s call would spell disaster, madness and death amidst the most horrible tortures.[2]
