Ngai (also called Múrungu or Enkai) is the monolithic Supreme God in the spirituality of the Kikuyu (or Gikuyu) and the closely related Embu, Meru and Kamba groups of Kenya, and the Maasai of Kenya and Tanzania. Ngai is the creator of the universe and all in it. Regarded as the omnipotent God, the Kikuyu, Embu, Meru, Kamba and the Maasai of Kenya worshiped Ngai facing the Mt. Kirinyaga (Mount Kenya) while prayers and goat sacrificial rituals were performed under the sacred Mugumo tree (a fig tree species).
