True Masters Are Both Brutal and Refined
In the martial arts, the really good teachers cultivate in their students an acute sensitivity to various stimuli. Your nerve endings are teased and jolted, your reflex actions made more subtle, and, for some of us, the result is a change in the ways we see the world and exist within it. The true masters are both brutal and refined, compassionate torturers, and guides who lead you to places where you will stand alone, confronting age-old fears that snarl in the abyss.
Once you’ve gone into that void and come through to the other side, it changes you. You glimpse it sometimes in people who’ve had a similar experience. I see it in my teacher’s face in his rare unguarded moments. And I see it in the mirror. It doesn’t make us better than other people, just different.
— Tengu, chapter 2
