While they may have practiced deception in minor matters, the great majority of the shamans believed in the fact of their spirit possession. Women who were able to throw themselves into a trance or a cataleptic fit became powerful shamanesses; later, such women became prophets and spirit mediums. Their cataleptic trances usually involved alleged communications with the ghosts of the dead. Many female shamans were also professional dancers.

But not all shamans were self-deceived; many were shrewd and able tricksters. As the profession developed, a novice was required to serve an apprenticeship of ten years of hardship and self-denial to qualify as a medicine man. The shamans developed a professional mode of dress and affected a mysterious conduct. They frequently employed drugs to induce certain physical states which would impress and mystify the tribesmen. Sleight-of-hand feats were regarded as supernatural by the common folk, and ventriloquism was first used by shrewd priests. Many of the olden shamans unwittingly stumbled onto hypnotism; others induced autohypnosis by prolonged staring at their navels.

While many resorted to these tricks and deceptions, their reputation as a class, after all, stood on apparent achievement. When a shaman failed in his undertakings, if he could not advance a plausible alibi, he was either demoted or killed. Thus the honest shamans early perished; only the shrewd actors survived.

It was shamanism that took the exclusive direction of tribal affairs out of the hands of the old and the strong and lodged it in the hands of the shrewd, the clever, and the farsighted.

Spirit conjuring was a very precise and highly complicated procedure, comparable to present-day church rituals conducted in an ancient tongue. The human race very early sought for superhuman help, for revelation; and men believed that the shaman actually received such revelations. While the shamans utilized the great power of suggestion in their work, it was almost invariably negative suggestion; only in very recent times has the technique of positive suggestion been employed. In the early development of their profession the shamans began to specialize in such vocations as rain making, disease healing, and crime detecting. To heal diseases was not, however, the chief function of a shamanic medicine man; it was, rather, to know and to control the hazards of living.

Ancient black art, both religious and secular, was called white art when practiced by either priests, seers, shamans, or medicine men. The practitioners of the black art were called sorcerers, magicians, wizards, witches, enchanters, necromancers, conjurers, and soothsayers. As time passed, all such purported contact with the supernatural was classified either as witchcraft or shamancraft.

Witchcraft embraced the magic performed by earlier, irregular, and unrecognized spirits; shamancraft had to do with miracles performed by regular spirits and recognized gods of the tribe. In later times the witch became associated with the devil, and thus was the stage set for the many comparatively recent exhibitions of religious intolerance. Witchcraft was a religion with many primitive tribes.

The shamans were great believers in the mission of chance as revelatory of the will of the spirits; they frequently cast lots to arrive at decisions. Modern survivals of this proclivity for casting lots are illustrated, not only in the many
