“I have much to teach you. Come and learn the art of war from the one who invented it. (Takeshi)”
“The master is not the one who teaches; it's the one who suddenly learns.”
“If you would thoroughly know anything, teach it to others. One who ceases to learn cannot adequately teach.”
“...No one teaches well unless he has first learned well; no one learns well unless he learns in order to teach. And both learning and teaching are vain and unprofitable unless accompanied by practice.”
“He continues to teach because it provides him with a livelihood; also because it teaches him humility, brings it home to him who he is in the world. The irony does not escape him: that the one who comes to teach learns the keenest of lessons, while those who come to learn learn nothing.”
