Knowledge in martial arts actually means self-knowledge. A martial artist has to take responsibility for himself and accept the consequences of his own doing. The understanding of JKD is through personal feeling from movement to movement in the mirror of the relationship and not through a process of isolation. To be is to be related. To isolate is death. To me, ultimately, martial arts means honestly expressing yourself. Now, it is very difficult to do. It has always been very easy for me to put on a show and be cocky, and be flooded with a cocky feeling and feel pretty cool and all that. I can make all kinds of phoney things. Blinded by it. Or I can show some really fancy movement. But to experience oneself honestly, not lying to oneself, and to express myself honestly, now that, my friend, is very hard to do.
