In randori we learn employ the principle of maximum efficiency even when we could easily overpower an opponent.

Judo helps us to understand that worry is a waste of energy.

In Randori we teach the pupil to act on the fundamental principles of Judo, no matter how physically inferior his opponent may seem to him, and even if by sheer strength he can easily overcome him because if he acts contrary to principle his opponent will never be convinced of defeat, no matter what brute strength he may have used.

For one thing, Judo in reality is not a mere sport or game. I regard it as a principle of life, art and science. In fact, it is a means for personal cultural attainment.

Face your fear, empty yourself, trust your own voice, let go of control, have faith in outcomes, connect with a larger purpose, derive meaning from the struggle.

Nothing under the sun is greater than education. By educating one person and sending him into the society of his generation, we make a contribution extending a hundred generations to come.

Judo should be free as art and science from any external influences, political, national, racial, and financial or any other organized interest. And all things connected with it should be directed to its ultimate object, the benefit of Humanity.

Walk a single path, becoming neither cocky with victory nor broken with defeat, without forgetting caution when all is quiet or becoming frightened when danger threatens.

Consider fully, act decisively.

The pine fought the storm and broke. The willow yielded to the wind and snow and did not break. Practice Jiu-Jitsu in just this way.

Carefully observe oneself and one's situation, carefully observe others, and carefully observe one's environment. Consider fully, act decisively.

Walk a single path, become neither cocky with victory nor broken with defeat.

It is not important to be better than someone else, but to be better than yesterday.

The purpose of the study of judo is to perfect yourself and to contribute to society.

In randori, one must search out the opponent's weaknesses and be ready to attack with all the resources at his disposal the moment the opportunity presents itself, without violating the rules of judo.

The teaching of one virtuous person can influence many that which has been learned well by one generation can be passed on to a hundred.
