Karate begins and ends with courtesy.

The correct understanding of Karate and its proper use is Karate-do. One who truly trains in this do [way] and actually understands Karate-do is never easily drawn into a fight.

Don't pretend to be a great master and don't try to show off your strength.

When two tigers fight, one is certain to be maimed, and one to die.

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.

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.

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.
