"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."

And many kinds of creatures must have died, Unable to plant out new sprouts of life. For whatever you see that lives and breathes and thrives Has been, from the very beginning, guarded, saved By it's trickery for its swiftness or brute strength. And many have been entrusted to our care, Commended by their usefulness to us. For instance, strength supports a savage lion; Foxes rely on their cunning; deer their flight.
