Seek perfection of character. Be faithful. Endeavor. Respect others. Refrain from violent behaviour.

Karate is like boiling water, if you do not heat it constantly, it will cool.

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.

Put Karate into your everyday living, that is how you will see true beauty.

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.

What you have been taught by listening to others' words you will forget very quickly; what you have learned with your whole body you will remember for the rest of your life.

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.
