 "Ling" is the mediating bivalency, the "medium", between yin and yang, that is "disorder" and "order", "activity" or "passivity", with "yang" usually preferred over "yin".More specifically, the "ling" power of an entity resides in mediation between the two levels of order and disorder, activity and passivity, which govern social transformation.The mediating entity itself shifts of status and function between one level and another, and makes meaning in different contexts.
