You and your opponent are one. There is a coexisting relationship between you. You coexist with your opponent and become his complement, absorbing his attack and using his force to overcome him.
Emotion can be the enemy, if you give into your emotion, you lose yourself. You must be at one with your emotion, because the body always follows the mind.
A man strikes you, make him bleed. He makes you bleed, you break his bones. He breaks your bones, kill him. Being hit is inevitable, strike back twice as hard.
