The supreme being, our single God, is known as Oludumare, another form of the word. Our mouths speak and eat and breathe. Our faces are different from all others and provide our physical identities. An individual may come to Earth with a wonderful destiny, but if he or she comes with bad character, the likelihood of fulfilling that destiny is severely compromised. Character is essentially unchangeable.
Destiny is more complex.
In Ifa we believe that we choose our own destinies. And we do this through the auspices of the Orisa Ajala Mopin, or the god of Ori. Ajala is responsible for molding the human head, and it is believed that the Ori we choose determines our fortunes or tribulations in life. Ajala's domain is close to Oludumare's, and it is he who sanctions the choices we make. These choices are documented by what we call Aludundun deities.
