Inhabiting the southwestern part of modern-day Nigeria and the southernmost part of Benin, lie the Yoruba people. People who practice the traditional Yoruba religion believe in 401 gods, who are in charge of governing various aspects of the world and human life, known as orisha. Oshun, or Osun, is an orisha (deity) of the Yoruba people of southwestern Nigeria. She is typically associated with purity, water, fertility, love, and sensuality. She is most commonly called the river orisha, or goddess, in the Yoruba religion. She is also considered to be one of the most powerful orishas.
