Couldn't find Osha. Found Oshun, in Wikipedia under Yoruba religion:
Wife of the former Oba of Oyo called Shango (another Yoruba Orisha, see below) is said to've turned into a river in Osogbo.

She is associated with several powers, including abilities to heal with cool water, induction of fertility and the control of the feminine essence.

The Osha provides the stories, history, types and manner of divination, the procedures of vestment, names of the deities and everything which is part of the Yoruba/Santeria Religion. A bold work of great intimacy with "The Religion.
