"Do not follow the ways of the
men of old.
Instead, seek what they sought."
So the traditional arts were a response to a problem. It seems that the problem, an attack, still exists. But the nature of the attack has changed so the nature of our training, our solution, must also change.
So in essence we are all still training in an art where we are seeking the defence to an attack. It's just that the shape of the attack has changed.
