Judo is the way to use most efficiently one's mental and physical strength.

By training, one should discipline and cultivate his or her body and spirit
through the practice of techniques for offense and defense, thereby to master
the essence of this way. And, by dint of these means, it is the ultimate goal
of Judo to build oneself up to perfection and benefit the world.
