Also remember that kata contains principle or concepts as well as techniques.
The individual techniques are less important than the concept or principles behind them.
Example. If I know how to use my hips for power generation, it doesn't matter what technique
is at the end of that hip twist. Kick, punch,shuto,block...doesn't msatter. I have learned to use my hips and can now always apply that concept/principle.
Once you learn the concepts or principles, you can apply them to any range
. Including fighting on the ground or standing grappling.
My very first submission ever in BJJ was executed in the standing position, after we clinched, using a principle and technique from Kata Wansu.
It's there, you just have to find it. But please DO NOT
attempt to find it by laying on your back and practicing Naihanchi! That's just silly!
