Bruce Lee discusses the differences between eastern and western thinking when it comes to martial arts. He tells a story of a master swordsman who is able to catch flies with chopsticks to intimidate three men who were insulting him. While a westerner may see this as an unrelated skill, an easterner understands it demonstrates the master's complete control and presence of mind. Lee believes the goal of martial arts in the east is to use techniques like kicks and punches to conquer the mind, not just opponents. True mastery is achieving a state of "emptiness" and balance within oneself, allowing one to respond fluidly to any situation.
