Ori
Ori, literally head, is the Yoruba concept of a person's spiritual intuition. It is a spark of consciousness set into the human essence, and is often personified as an orisha in its own right.
Whatever a person becomes, or whatever happens in a life, is held to be as destined by Ori, so Ori is worshipped like the orisha. When things go wrong it is consulted and appeased, and a person with a balanced character is aligned with his Ori, his divine self.
