"in training, in studying jiu-jitsu, one is constantly humbled by the continual reappearance of the lessons of the first class: technique will conquer strength; self-control will defeat arrogance; one need not win, one need only endure, conserving strength until one may improve the position. these are the hard-won pillars of wisdom, leaned only through constant application in practice and free-training (bouts with other students)."
"here, through one's own trail and failure, is revealed an astonishing truth about human conflict: that an opponent must move, in order to better his position. that is, in order to advance toward his goal, he must commit himself; and any commitment, that is, any progression from a state of perfect balance, must create, in him, a vulnerability."
