Is Power Control?

From the movie ‘Man of Tai Chi’: 

Master: You must meditate.
Tiger: Why?
Master: To clear your mind, guide your chi and gain control.
Tiger: I have control.
Master: No, you have power, not control.
Tiger: Power is control.
Master: That is an illusion.
Tiger: It is not an illusion. It’s reality.

From meditative practices, there will be mindfulness, of your state of mind, which controls your physical energy. Since power is useless, and even dangerous without control, control of whatever much or little power you have is the primary power to have, which can only be there with mindfulness.
