There is only ONE type of power.
And that is the amount of effort or time it takes to complete a task with the human body.
That is power.
How that ability is cultivated is one thing, how it is expressed is another.
There is no internal nor external way to move a 200lbs wall unit from A to B, nor is there an internal or external or taichi or wing chun method of running the 100 meters in less than 11 seconds.
There is no taichi or wc or shaolin method of lifting your 100lbs big screen TV set.
There is just the right way, and the wrong way, there is just having the "power" to do it or NOT having it.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
