Instead of opposing force by force, a gung fu man completes his opponent's movement by accepting his flow of energy as he aims it, and defeats him by borrowing his own force.
Master Lee also references pedaling a bicycle; pushing one pedal while releasing the other is the only way to move forward. "The utilization of energy and movement in gung fu should flow on continuously without cessation."
Working it out in my head...analyzing how I can use my own energy, flow with it, allow it to move continuously, gentle and strong, without cease. Instead of struggling against my own nature, allowing my certain type of flow, complete my own movement... If I am struggling with fear about my ability or an upcoming task, how can I use that fear (energy) to complete the task? Accept the flow of energy that comes from the fear (overwhelment/lack of clear direction/fear of failure), rather than taking it as a punch to my motivation (thus ending my action), crouching down to hide and deflect.... How can I stay standing...?...allow the punch (fear), move with the punch (energy created by anxiety), utilizing that force to defeat (act) and overcome (complete fearsome task)... Moving with the flow of the fear...just do it...?
