I don't think that's what he's talking about. He's saying that in order to improveyhour technique, you must use what you know. I think that depends on your definition of violence, though. these days, you can step into a ring. I don't consider sanctioned fights as "violence" (even though it CAN be looked at as such, which is why I said it depends on your definition.)
