I just had another idea for this. An art where the techniques are taught, but the core principle obscured until the very end. So when you get that core principle, you have to relearn everything about the art. For example: You train the forms. You train them specifically based on movements, and are not given any application. You must master all of the forms before the application is revealed. You then learn the first layer of the application. It is a game, or sport, based on clinching and tagging marked spots on your opponent's uniform. This game serves no martial application, and mastering this game will teach you absolutely nothing about fighting. You then learn how to apply the game in a martial setting. The marked spots correspond to pressure points and leverage points, and the martial application is one that involves using these points to control your enemy. The forms and the game must be relearned and remastered with this new application in mind. But you're only going to be good at fighting against people who use this martial art, because you've learned nothing about how to apply it to a real fight. You then learn how to apply the martial game into a real fight. Once again, everything must be re-learned with the new application in mind.
