Juok (Jwok), the supreme being, created the world, its plants, animals, and people. There are three levels of belief: the recognition and worship of Juok, the cult of Nyikang and the kings in whom he has been reincarnated, and the cult of the ancestral spirits. Juok is spirit that is universal, formless, and invisible like the air. He is above Nyikang and men, though he is approached principally through Nyikang. Sacrifices are made to Nyikang to cause him to move Juok to send rain, to prevent misfortune, remove sickness.
Using different types of earth, God created people in three types, black, white and brown. The white man was made from white loam; the brown man was made from the desert sand; and the black man was formed from the fertile riverside clay. See also: Nyikang, Ukwa.
