You taught at the Governor's School for the Arts. That is wonderful. Your letter said only teaching music, but other times, you are always teaching music, karate, and Zen. Our mind has three aspects. Will makes goodness.
Emotion makes beauty.
Intellect makes truth. So, these three aspects come from one mind. You have one body, one mind. When you are teaching karate, you must teach strong will, complete goodness. Next, when you are teaching music, you must teach high emotion.
