In randori we learn to employ the principle of maximum efficiency even when we could easily overpower an opponent. Indeed, it is much more impressive… - Kanō Jigorō

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.

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". Human sacrifice is a matter of ancient history.

Judo is the way to the most effective use of both physical and spiritual strength. By training you in attacks and defenses it refines your body and your soul and helps you make the spiritual essence of Judo a part of your very being. In this way you are able to perfect yourself and contribute something of value to the world. This is the final goal of Judo discipline.
