Any man will be able, after sufficient practice, to accomplish remarkable feats of strength, but he may go only so far and no farther. There is a limit to human physical strength that no one can exceed.

Karate-do strives internally to train the mind to develop a clear conscience, enabling one to face the world honestly, while externally developing strength to the point where one may overcome even ferocious wild animals. Mind and technique become one in true karate.

One whose spirit and mental strength have been strengthened by sparring with a never-say-die attitude should find no challenge too great to handle. One who has undergone long years of physical pain and mental agony to learn one punch, one kick, should be able to face any task, no matter how difficult, and carry it through to the end. A person like this can truly be said to have learned karate.

The ultimate aim of Karate lies not in victory or defeat, but in the perfection of the character of its participants.

You may train for a long time, but if you merely move your hands and feet and jump up and down like a puppet, learning karate is not very different from learning a dance. You will never have reached the heart of the matter; you will have failed to grasp the quintessence of karate-do.

There is no place in contemporary Karate-do for different schools. Some instructors, I know, claim to have invented new and unusual kata, and so they arrogate to themselves the right to be called founders of "schools". Indeed, I have heard myself and my colleagues referred to as the Shoto-kan school, but I strongly object to this attempt at classification. My belief is that all these "schools" should be amalgamated into one so that Karate-do may pursue and orderly and useful progress into man's future.

Karate is like boiling water: without heat, it returns to it's tepid state
