Babalawo or Iyanifa (also Babaaláwo in full, an pronounced Baba-a-láwo) is a Yorùbá title that denotes a Priest of Orunmila, the Yoruba god or Orisha of Wisdom operating through Ifá, the divination system. Orunmila in the Yorùbá tradition knows the past, present and future. The Babalawo as a Priest of Ifa can ascertain the future and how to deal with it through communication with Orunmila. This is done by consulting Ifa through the patterns of the divining chain (Opele) or sacred palm nuts called "ikin" on the traditionally wooden divination tray.
