Osun is often considered a minor Orisha (as if there could be such a thing) that plays an interesting role in the religion of Santeria. Osun is "received" as a member of the Warriors (Eshu, Oggun, Ochosi and, of course, little Osun) and applies His aché to protecting those who receive Him. Osun acts as a "look out" of sorts, providing an actual physical warning by falling to His side should danger approach! Should this occur, we "in the religion" will seek the guidance of Orunmila through a Babalawo to learn exactly what Osun's warning means, and how the trouble He predicts may be avoided.

The mysteries of Osun are received in a small metal cup topped with a small metal rooster and adorned with bells, all perched atop a thin metal stand. When He is introduced to a believer's home, He is placed high on a shelf (ideally higher than the recipient's own head) so He has an ample vantage point to perform His sacred function.

Ebo (offerings) are never made to Osun directly by those who receive Him, for Osun is the servant of Eshu, and Eshu is responsible for sharing scraps of His own meal with Osun as He pleases. It is taboo for anyone else to make offerings to Osun, except for the Babalawo, who includes Osun in the annual feeding of the three other Warriors, or when prescribed through Ifa Divination.
