The Yin Prana allows a Kuei-jin to to tap into and manipulate his internal Yin energy. Like Yang Prana, Yin Prana relies on motions and postures to utilize the various powers, but these motions are a far cry from the frenzied katas of the Yang Prana. Yin Prana motions are slow, graceful, and deliberate. Nonetheless, as with the Yang Prana, wielders of this Discipline must have relative freedom of movement.
