The belief in the transmigration or reincarnation, found in many peoples who have reached a certain level of culture, as for example the India. Where we see more clear is in the tribes of West Africa. According to Delafosse (1912), every living creature, as every natural phenomenon, depends on its nature of a niama (dynamic spirit). The nima of the dead person resides where most pleases him: in the corpse, in the hut, a sacred object or in the body of another living person, whose niama it absorbs. Thus certain magicians attributed his virtue and power to the possession of the niama a genius or a deceased person. Niama of a man you have not practiced, due rites, can reincarnate himself in a solitary animal or a human being loses his sanity. Ideas related to the immortality of the soul, are found in all peoples. Although it is not possible to compare or put on the same level the emerging doctrines of the savages, with the perfectly elaborated of the Egyptians; at the bottom of all them there is a same feeling, that, after death, divinity will reward good actions and punish the bad, and that this world, as it is now constituted, is not eternal, but that will come a day that will disappear forever.

We find different doctrines: – 1 of the Savages: among the tribes of central Australia, the belief that the human personality is maintained in the form of a spirit, which embodies in children born is very common. But in the intervals between two successive incarnations, spirits take refuge in ponds of water, trees, rocks, etc., and from there lurk the passage of women, within which they penetrate and engender new being. Elsewhere in Australia, does not believe in the rencarnacion, but the person who has died once, he moved to a distant region, which is in heaven, or under the seas where everyone gathers.
