"We talk about martial arts having three levels. The first level we talk about the physical: Sword on your hand is part of your body. You use like it's your arm. The second part, you don't (really) have a sword but the sword in your heart. Before the physical contact, maybe you can scare them. Maybe you can use imagination, talking. Make them afraid. Third level, the highest level, you love your enemy. In other words, mercy is courage." --Jet Li
