"The mark of a successful shaman is the degree to which he imbues his performance with his own singular style. While he is possessed, in a state where the shaman is very deeply taken by his roles, his ordinary daily self is effaced or replaced. Then follows a transformation of voice, movements, gestures, and even thoughts and feelings. This transformation is strengthened by careful use of makeup, masks, costumes, props, and audience participation."
