A Buddhist phones the monastery and asks the monk, “Can you come to do a blessing for my new house?”

The monk replies “Sorry, I’m busy.”

“What are you doing? Can I help?”

“I’m doing nothing.” replied the monk. “Doing nothing is a monk’s core business and you can’t help me with that.”

So the next day the Buddhist phones again, “Can you please come to my house for a blessing?”

“Sorry,” said the monk, “I’m busy.”

“What are you doing?”

“I’m doing nothing,” replied the monk.

“But that was what you were doing yesterday!” said the Buddhist.

“Correct”, replied the monk, “I’m not finished yet!”
