Here we have manifestly the wide-spread phenomena of Possession. In these tribes there are no professional priests. The magicians, though in a sense the intermediaries between men and the higher powers, are not charged with the duty of offering sacrifice and prayer. In South Africa, among the Bantu tribes, also, there are {108} no professional priests. Ancestor-worship is the religion; and the only worship paid is paid to the _manes_ of the dead. The proper person to offer sacrifices is the head of the family for the time being. But medicine-men or magicians form a regular profession, which is divided into a number of branches. For some of these branches initiation by the spirits of the dead is not necessary. For others it is indispensable. Frequently, however, the same man combines the practice of several branches of the art. All who practise openly are recognized as White Wizards, exercising their powers for the wellbeing of society, in defence of the established order. Yet these very men sometimes boast of being _baloyi_, a term by which evil wizards are generally known. They claim to be more powerful than ordinary wizards, able to discover and baffle their tricks, and to kill. Moreover, there are good _baloyi_, who use their power to bless. They are sometimes sent by ancestral spirits to increase the produce of the fields, and then they are said to have bewitched the fields to make them bring forth more fruit. Thus it is clear that a hard and fast line cannot be drawn between the social and the antisocial magicians, at least among some of the Bantu tribes. One of the chief branches of the profession is that of exorcist. Now no man can set up as an exorcist without having been himself possessed by the spirits and exorcised. This is indeed the regular method of initiation, for a man is not merely restored to ordinary life by exorcism; he is also aggregated to the society of magicians; he enters a new life; he becomes a neophyte among the practitioners, and must undergo further probation which may result in his becoming more than an exorcist--he may become clairvoyant or a diviner, a prophet or a worker of marvels; he may cure diseases or cause the rain to fall. Many practitioners {109} profess more than one of these accomplishments; the most distinguished profess several.[109.1] How far the phenomena of possession are voluntary need not here be discussed. The Zulu or Xosa patient (if we may call him so) becomes sickly and abstinent; he distinguishes himself by dreams and visions, and begins to talk of his intercourse with spirits of the dead; he becomes “a house of dreams”; he is hysterical; he sings; he behaves as though he were out of his mind; he is possessed by an _Itongo_, an ancestral spirit. Then he is admitted to the society of the magicians and receives instruction from them. Finally, he is accounted a new creature, whose intercourse with spirits and share in their supernatural powers is recognized by everyone.[109.2]
