Voodoo Priest

Houngans (Male Voodoo Priest) or Mambos (Female Vodou Priest) are usually people who were chosen by the dead ancestors and received the divination from the deities while he or she was possessed. His or her tendency is to do good by helping and protecting others from spells, however they sometimes use their supernatural power to hurt or kill people. They also conduct ceremonies that usually take place "Amba Peristil" (under a Vodou Temple). However, non-Houngan or non-Mambo as Vodouisants are not initiated, and are referred to as being "bossale"; it is not a requirement to be an initiate to serve one's spirits. There are clergy in Haitian Vodou whose responsibility it is to preserve the rituals and songs and maintain the relationship between the spirits and the community as a whole (though some of this is the responsibility of the whole community as well). They are entrusted with leading the service of all of the spirits of their lineage. Sometimes they are "called" to serve in a process called "being reclaimed", which they may resist at first. Below the houngans and mambos are the hounsis, who are initiates who act as assistants during ceremonies and who are dedicated to their own personal mysteries.
