Each member of the magical Corporation provides turn sacrifice, and no one is allowed to evade this obligation, even if as a result of his fall victim to the next of kin. A popular song recorded on the island of Pemba, gives an idea of ??this custom: it is groaning mother who sacrificed her daughter, so to speak, a bad bargain, selling her soul, because not received a return of what to expect. In the cases described above, a sacrifice devoured after the death and burial (whether it enliven always kill again, as in Nyasaland and Zanzibar, it is not clear), but the procedure, according to the stories of some West African tribes (eg, mpongve) is different. Here, if you can believe the stories, in the case enters the hypnosis. By all indications, sorcerers peacefully asleep in their huts, but their "true essence," or, as we would say the Theosophists, their astral bodies, are sent into the woods on the night orgy, taking with them the same or a similar way the "essence" of his victim, recovered "heart of life" and devour it. The person did so die if swallowed his whole life force. If the wizards do not eat it right away, the person begins to suffer from many diseases, but it can get better, even if it remains a particle of its vitality.
