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.

In battle, do not think that you have to win. Think rather that you do not have to lose.

The secret principle of martial arts is not vanquishing the attacker, but resolving to avoid an encounter before its occurrence. To become an object of an attack is an indication that there was an opening in one's guard, and the important thing is to be on guard at all times.

To search for the old is to understand the new.

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.

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.

When you look at life think in terms of karate. But remember that karate is not only karate -- it is life.
