Zhong Ding

This is a VERY interesting observation from a book I am currently reading.

“Central equilibrium, in turn, is primarily a mental/spiritual function.  A physical manifestation of zhong ding is a perfectly balanced body.  A perfectly balanced body, with the qi sunk to the dantian, is achieved only by a calm and peaceful mind.”  

(Yang Yang, Taijiquan: The Art of Nurturing, The Science of Power, 2005, pg. 30)
