Nice,
some good insights talks to some the post mentioned here
“Within the thirteen dynamics, being centered is the priority. The other twelve – warding off, rolling back, pressing, pushing, and so on – are just there to assist. If you have that quality of being centered, then you have everything. When none of your postures exist independent from centeredness, then you’ll be ready to talk about applying them.
Chen Pinsan [Chen Xin] said: ‘Open and close, emptiness and fullness – these are the keys to the art.’ We should understand that when we don’t have centeredness, there’s no opening and closing.
“For example, the opening and closing of a door depends upon its hinges. If a hinge slips into an awkward angle, will it open or close well? Without opening and closing, you won’t be able to seek emptiness and fullness.
Thus you can understand that any emptiness or fullness you feel when not centered is neither emptiness nor fullness. Being without a sense of centeredness is like a blind man’s sight, a lame man’s steps, touching when without a sense of touch, perceiving when without ability to perceive.
It says in the classics: ‘Your posture must be straight and comfortable.’ That word ‘comfortable’ is the indicator of being centered.”
