I am currently reading Kata: Essence of Bujutsu Karate by Kenji Ushiro. This is more personal research in to Ki and utilising it in martial arts. Of particular interest to me is the concept of "penetrating your opponents mind".
Unfortunately, the book falls a bit short of really explaining how to do this and says that you need to have a teacher who knows how to do it, to show you and pass it on to you. Is this a trick to make me buy a Ushiro seminar ticket? Hmmm, I don't know.
I can certainly say that I am working on using a unified mind+body with consciousness during my kata - and it feels good.
This is my journey towards being in the moment during kumite and letting the techniques happen rather than thinking about them.
