The belief in temporary incarnation or inspiration is world-wide. Certain persons are supposed to be possessed from time to time by a spirit or deity; while the possession lasts, their own personality lies in abeyance, the presence of the spirit is revealed by convulsive shiverings and shakings of the man’s whole body, by wild gestures and excited looks, all of which are referred, not to the man himself, but to the spirit which has entered into him; and in this abnormal state all his utterances are accepted as the voice of the god or spirit dwelling in him and speaking through him.
