All observers speak in enthusiastic language of the temperament and moral qualities of the Tunguses, and particularly of those groups that roam the forests about the Tunguska tributaries of the Yenisei, which take their name from these daring hunters and trappers. "Full of animation and natural impulse, always cheerful even in the deepest misery, holding themselves and others in like respect, of gentle manners and poetic speech, obliging without servility, unaffectedly proud, scorning falsehood, and indifferent to suffering and death, the Tunguses are unquestionably an heroic people[619]." A few have been brought within the pale of the Orthodox Church, and in the extreme south some are classed as Buddhists. But the great bulk of the Tungus nation are still Shamanists. Indeed the very word _Shaman_ is of Tungus origin, though current also amongst the Buryats and Yakuts. It is often taken to be the equivalent of priest; but in point of fact it represents a stage in the development of natural religion which has scarcely yet reached the sacerdotal state. "Although in many cases the shamans act as priests, and take part in popular and family festivals, prayers, and sacrifices, their chief importance is based on the performance of duties which distinguish them sharply from ordinary priests[620]." Their functions are threefold, those of the medicine-man (the leech, or healer by supernatural means); of the soothsayer (the prophet through communion with the invisible world); and of the priest, especially in his capacity as exorcist, and in his general power to influence, control, or even coerce the good and evil spirits on behalf of their votaries. But as all spirits are, or were originally, identified with the souls of the departed, it follows that in its ultimate analysis Shamanism resolves itself into a form of ancestry-worship. The system, of which there are many phases reflecting the different cultural states of its adherents, still prevails amongst all the Siberian aborigines[621], and generally amongst all the uncivilised Ural-Altaic populations, so that here again the religions strictly reflect the social condition of the peoples. Thus the somewhat cultured Finns, Turks, Mongols, and Manchus are all either Christians, Muhammadans, or Buddhists; while the uncultured but closely related Samoyeds, Ostyaks, Orochons, Tunguses, Golds, Gilyaks, Koryaks, and Chukchi, are almost without exception Shamanists.
