In all things man must have a clear mind. Karate is a technique that permits one to defend himself with his bare hands and fists without weapons. Just as it is the clear mirror that reflects without distortion, or the quiet valley that echoes a sound, so must one who would study Karate-Do purge himself of selfish and evil thoughts, for only with a clear mind and conscience can he understand that which he receives. He who would study Karate-Do must always strive to be inwardly humble and outwardly gentle. It is no exaggeration to say that the original sense of Karate-Do is at one with the basis of all martial arts.
Form is emptiness, emptiness is form itself.
The kara of Karate-Do means this. The correct understanding of Karate and its proper use is Karate-do. Students of any art, including Karate-do must never forget the cultivation of the mind and the body. To win one hundred victories in one hundred battles is not the highest skill. To subdue the enemy with out fighting is the highest skill.
