The Great Principle constitutes the ancient code of behaviour for all Kuei-jin, as set down by Xue himself. Each new disciple is commanded to learn and live by its precepts, called the Fivefold Way, in his or her every word and deed. In theory, the Great Principle embodies a Kuei-jin's personal directive of discovering and fulfilling his divine purpose under Heaven to atone for his sins as a mortal. Tightly linked to the Great Principle are the five orthodox Dharmas, that also originated in Xue's teachings.
