The Khasi religion, at the levels of both belief and practice (rites and rituals), traditionally, was neither codified nor elaborated uniformly across the Khasi Hills. The Khasi religion is neither church-based nor does it have an established priesthood. This means that, traditionally, it was not an organised religion that could give uniform and standardised rituals to society. Life-cycle events were marked by the performance of rites by an individual’s mother’s brothers. Their absence presents a situation of crisis. The book explains the ways in which such situations of crisis have been resolved. There are events other than life-cycle events that threaten an individual’s life. The book explains the rites performed to thwart evil influences on individuals. The book also highlights the role of the Ka Seng Khasi in preserving and perpetuating the Khasi belief and rites, and the historical conditions leading to its formation.
