The Religion of the Indians of California
“ In some regions, as among the Pomo and Yuki, the bear shaman was not thought as elsewhere to actually become a bear, but to remain a man who clothed himself in the skin of a bear to his complete disguisement, and by his malevolence, rapidity, fierceness, and resistance to wounds to be capable of inflicting greater injury than a true bear. Whether any bear shamans actually attempted to disguise themselves in this way to accomplish their ends is doubtful. It is certain that all the members of some tribes believed it to be in their power. ”
