Yamaguchi sensei

    "During your entire movement, if you consciously think, you will lose your way. You must not consciously think. All through nature, there is no separation of mind and body. If you do not separate mind and body, your center (tanden) will become full of spiritual ki. Then, after that, when striking out, the body can move freely. This is Aiki natural posture training".
