Loa are the spirits of Voodoo. They are also referred to as "mystères" and "the invisibles" and are intermediaries between Bondye (from French Bon Dieu, meaning "good God") and humanity.[1] They have their own personal likes and dislikes, songs, dances, ritual symbols (Veve), and special modes of service.[1]
The word Loa (lwa) comes from Yoruba olúwa (meaning "lord" or "God").[2]
There are many families of loa: Rada (also Radha), Petro (also Pethro, Petwo), Agwé, Nago, Kongo and Ghede (also Guede, or Gede) among others. In a ritual the loa are called down by the houngan (priest) or mambo (priestess) to take part in the service, receive offerings, and grant requests.
