Passage: Traditional African religions like the Serer religion (A at Roog) are adhered to by devout worshippers of Roog the supreme deity in Serer religion. The Serer ethnic group who adhere to the tenets of Serer religion (including those Senegalese who syncretize) honour the Serer pangool and have ancient rituals and festivals devoted to them. The religious affairs of Serer religion devotees are usually headed by the Saltigue (the Serer priestly class) which in ancient times was the preoccupation of the Serer lamanic class. Some of these religious festivals or ceremonies include the Ndut (rite of passage), Xooy (divination festival once a year in Fatick), and the Raan festival. Senegalese hold several ancient beliefs, such as small efforts of 'thanks' or demands, such as protection from water. They also place great importance on the Baobab tree, which is known as the "House of the Spirits." The baobab tree along with other sacred trees figure prominently in the Serer creation narrative. Among the Jola people, some religious festivals include the Samay, Kumpo and the Niasse.
Link Information: There are two main types of Ndut initiation rites. The first concerns the circumcision for Serer boys whilst the second concerns the initiation of Serer girls. Serer religion and culture forbids the circumcision of Serer girls (female genital mutilation). Only Serer boys are circumcised. Serer girls receive their initiation through njam or ndom (the tattooing of the gums). Preparation for the initiation starts early in childhood. In many cases, boys are circumcised when they reach 13 years old. However it is not uncommon for some to be circumcised when they are 19 to 26 years old. Likewise, Serer girls receive their initiation when they are 11 to 18 years. Answer: the circumcision for Serer boys
