Santeria is an earth religion. That is, it is a magico-religious system that has its roots in nature and natural forces. Each Orisha or saint is identified with a force of nature and with a human interest or endeavor. Chango, for instance, is the god of fire, thunder, and lightening, but he is also the symbol of justice and protects his followers against his enemies. He also symbolizes passion and virility and is often invoked in works of seduction. Oshun, on the other hand, symbolizes river waters, love and marriage. She is essentially the archtype of joy and pleasure.
