There is a pataki that describes how Oshun took the odus of Ifa from her husband Orunmila and developed the system of Merindilogun. It is an oracular system upon which the laws governing the culture of the Yoruba are based. That system is used as the principle framework for aleyoes, aborishas, omoorishas, iyalorishas and babalorishas. It serves to guide, teach, protect and heal any and all aspects of one's life.
