The cup was already full

A professor comes to ask about Zen. The tea goes over the rim and keeps going.

Chapter 03 of 12 in The masters were funny

A professor visits a Japanese master called Nan-in to ask about Zen. Nan-in serves tea. He fills the visitor's cup to the brim and then keeps pouring, and the tea goes over the rim, across the table, onto the mats. The professor watches as long as he can stand it. It's full, he says. No more will go in.

Like this cup, says Nan-in, you are full of your own opinions. How can I show you Zen unless you first empty your cup.

The version everybody knows comes from a book of Zen stories put together in the twentieth century, so I hold the history loosely. As a piece of comic timing it is close to perfect, because the master says nothing until the guest complains. He lets the joke run on the floor for a while.

The professor is no fool in the story. He is a professor. Being full is what he is good at. He has done the reading, he has the vocabulary, he came with questions that are probably quite sharp. What he cannot do is receive an answer, because every answer arrives into a container that is already at the brim and immediately becomes another thing he knows about.

I do this with everything I read on this subject. A piece lands, I feel the click, and within a day the click has been filed as a position I hold, which I can then defend at dinner. Nothing came in. The cup got a new label.

I hesitate at the phrase everybody quotes it for. Empty your cup. Said out loud it becomes another instruction to perform, and now I am the man sitting there trying to look empty, which is a full cup with a new decoration. Wanting to does not empty it.

What is left is to look down at the tea on the floor.
