Vodou is an oral tradition practiced by extended families that inherit familial spirits, along with the necessary devotional practices, from their elders. In the cities, local hierarchies of priestesses or priests “children of the spirits”, and ritual drummers comprise more formal “societies” or “congregations”. In these congregations, knowledge is passed on through a ritual of initiation in which the body becomes the site of spiritual transformation.
The Haitian voodoo is not only a religion recreated by the African slaves in the French colony called the Hispanola that included Haiti and the Dominican Republic, it is on the contrary a humanistic religion, a set of cultural traditions that constitute the foundation that unites the Haitian people in times of crisis and saves him from despair. Voodoo seeks to obtain the invulnerability of the believer by his circumstances with the higher divinity. In this way the believer tends to identify himself with the deity or with the deified objects, to become invulnerable as the same divinity. It is a religious practice that is not closed to the appearance of new luases (divinities). Man is one with nature, one with his gods, one with his environment, voodoo. The voodoo cults are syncretic from the colonial era, they mixed with the Christians.Voodoo is more than a synthesis of different African beliefs because it incorporates significant influences from Christianity. The word voodoo comes from the Fon language, spoken in Benin, meaning "a kind of power which is mysterious and, at the same time, fearsome." Voodoo is invested in all parts of Haitian life and has a considerable influence on each person and on each natural element. The voodoo pantheon consists of many Loas, which are generally associated with a Catholic saint. Despite the existence of these Loas, voodoo is essentially monotheist; in their conception, the Loas are neither more or less than the intermediaries between God and the human ones.
