Re: What's your sensei teaching you?
Kumagai Shihan once said to me: "I am not teaching you waza (technique) for the sake of technique. There is something underneath the waza that we cannot get to any other way, something very deep. So we do the waza over and over again and little by little we see it." Just exactly what lies underneath waza he was reluctant to say, perhaps because words will always fail to reach it.
