Houngan is the term of a Haitian Voodoo priest.
Houngans can be chosen in three ways – through a dream-like experience in which a lwa informs that they are chosen as their servants, having visions, or through degradation and transference rituals after an important houngan's death. Each houngan has authority in their own temple, however, there is no official hierarchy within Haitian Vodou.
To become a houngan, one must first undergo initiation. First, a period of isolation and seclusion (typical of an African initiation) known as Kouche Kanzo must take place. Then Lave Tèt (“the washing of the head”) takes place, which is a ceremony where one's hair is washed seven times with a mixture made of plants to spiritually cleanse in order to better receive the lwa. Then, various rituals and sacrifices are made. This is often a lengthy and expensive process, as numerous items have to be purchased such as the presentation of Iwa's favourite food and drinks, and special handmade ceremonial clothes.
