the tribe expanded and people moved further away from this point, other hilltops would be set aside as being sacred. Evidently, the first kaapkoros took place very soon after the Kalenjin settled in Kenya—or even long before that time. People gathered on average once a year at kaapkoros, where worship would be led by the priests, known as Tisiik. Mabwaita is a term used by the Kipsigis section for the family altar or prayer tree which was positioned to the east of the house as one exited from the door. The Nandi and Keiyo sections called it korosyoot. This was a duplicate of the one at kaapkoros and was the centre for worship and ceremonies connected with the home and family. Sach ooraan is a Kalenjin term used for the intersection of two or more paths or roads. Sach ang'wan is used for the place where four paths or roads branch off. Years ago when a crossroad was being used for a ceremony or practice, it was considered to be a shrine. It was remembered ever afterwards that the spot had been used for the removal of something bad. Children were not allowed to go near a shrine at an intersection. Casting a leaf at sach ooraan was a form of prayer to Asis to drive away disease. Traditional knowledge Kamuratanet Kamuratanet is a Kalenjin traditional process of teaching its members appropriate behavior, knowledge, skills, attitudes, virtues, religion and moral standards. Kamuratanet provides parameters that are used to determine what is acceptable and normal and what is not acceptable, and therefore abnormal. Though carried out throughout an individual's lifetime, it is formalized during yatitaet (circumcision) and subsequent tumdo (initiation). Medicine Traditional Kalenjin medicine recognized both supernatural and technical skills, with male practitioners more associated with the former and female practitioners with the latter. When a person fell ill, it was attributed to an angry spirit, often of a relation, and a cleansing ceremony was performed following which treatment was carried out. Medicines were made out of bark, roots and leaves of various trees and plants. Surgery was practiced and limbs skillfully set and amputated. Cupping therapy was frequently made use of and wounds were at times cauterized using a fire-stick. Chepkerichot The Nandi chepkerichot corresponds to an ordinary medical practitioner. In fact Nandi doctors of the 21st century are called Chepkerichot. Both males and females could attend this role, except
