The Duke and the Wheelright
Duke Huan was reading a book in the hall.
Wheelwright Pian, who had been chiseling a wheel in the courtyard below, set down his tools and climbed the stairs to ask Duke Huan: "may I ask what words are in the book Your Grace is reading?"
"The classic of a famous sage." the Duke responded.
"Is he still alive?"
"Oh no, he is long dead"
W'heelwright Pian said, "In my case I see things in terms of my own work. I chisel at a wheel. If I go too slow, the chisel slides and does not stay put. If I hurry, it jams and doesn't move properly. When it is just right, I can feel it in my hand and respond to it from my heart. I can explain this to my son, but I cannot pass on the skills to him. That is why at seventy years old, I am still making wheels.”
Moral: Some things can't be learned from books.
