“Who is the best swordsman?” asked a warrior of his master.

“Go to the field near the monastery,” his master answered. “There is a rock there. I want you to insult the rock.”

“But why would I do that?” the disciple asked. “The rock will not respond.”

“Well, then attack it with your sword,” the master said.

“I won’t do that, either,” the disciple answered. “My sword would break. And if I attack the rock with my hands, I’ll injure my fingers and have no impact on it. That wasn’t what I asked. Who is the best swordsman?”

“The best is the one who is like the rock,” said his master. “Without unsheathing a sword, it demonstrates that no one can conquer it.”
