This may seem like a really dumb question, but if I could get the lightbulb to come on, I think it would really help me. I have studied several martial arts in my lifetime: Karate', Judo, Japanese Jiu Jitsu and others. I can't say I mastered any of them, but I think I understand them. So in the striking arts, I get that power is generated from the ground up, pivoting various joints in the body to create power in a strike. Of course, there is a lot of nuance in positioning, body movement and footwork to get in position to deliver each strike. In Judo, I get that every throw involves a grip, an off balancing, a re-positioning and an execution. There are throws where the opponent is taken off his center of gravity and there are throws where the person throwing displaces the opponent's center of gravity. I may not have used all the right words to describe all the above, but in my mind, it seems clear and generally, I can do it. But I have been taking BJJ for about six months now and while I have learned the positions like guard, side control, mount, etc. and several combinations of moves to get from one to the other, the whole art still seems a mystery to me. I am fascinated by it and determined to learn, but I still don't get the overall logic of it. When I roll, I see that it works, but I find myself wondering what even happened a lot. When the instructor teaches a sequence I am often amazed how ingenious it is, but I wonder, "How did anyone ever figure that out? What principles were they following? Am I making any sense? Is there any way to an intellectual understanding, or do I just need to keep rolling until the light comes on?
