The monotheistic Maasai worship a single deity called Enkai or Engai. Engai has a dual nature: Engai Narok (Black God) is benevolent, and Engai Na-nyokie (Red God) is vengeful. There are also two pillars or totems of Maasai society: Oodo Mongi, the Red Cow and Orok Kiteng, the Black Cow with a subdivision of five clans or family trees. The Maasai also have a totemic animal, which is the lion; however, the animal can be killed. The way the Maasai kill the lion differs from trophy hunting as it is used in the rite of passage ceremony. The Mountain of God, Ol Doinyo Lengai, is located in northernmost Tanzania and can be seen from Lake Natron in southernmost Kenya. The central human figure in the Maasai religious system is the laibon whose roles include shamanistic healing, divination and prophecy, and ensuring success in war or adequate rainfall. Today, they have a political role as well due to the elevation of leaders. Whatever power an individual laibon had was a function of personality rather than position. Many Maasai have also adopted Christianity and Islam. The Maasai are known for their intricate jewelry and for decades, have sold these items to tourists as a business.
