A monk was sitting in meditation when the abbot of the monastery walked by.
“What are you doing?” the abbot asked the monk.
“I’m sitting in meditation to become a buddha,” replied the monk.
The abbot picked up a brick and began polishing it. The monk asked the abbot, “What are you doing?”
The abbot replied, “I’m polishing a brick to make a mirror.”
The monk asked, “How can you polish a brick to make a mirror?”
“How can you sit in meditation and make a buddha?” the abbot replied.
