Here’s one of my favourite stories about teaching.
A student goes to the head monk in the temple and asks him, “What’s the biggest problem in teaching Zen?”
The master replies, “Teaching deaf people. No matter how you try to explain, they don’t understand.”
The student ponders this for a moment. He goes to one of the other senior monks and repeats the answer. “What do you think about this?”
The monk mutters something under his breath. The student asks him again. The monk turns away and mumbles something. The student walks in close and asks, “What are you saying?”
The monk replies, “The master is wrong. You’re not deaf.”
