An old monk was living alone in the mountain close to Lok Yeung ??in China. One day, a young monk travelled pass by the old monk’s temple and asked to stay overnight. The old monk accepted.
Before the old monk meditate at night, he heard some noise that was coming from the pond outside the temple; so he went out to check what was happening. When the old monk arrived to the pond, he saw the young monk was very busy running around the pond.
The old monk asked the young monk, “What are you doing?â€
The young monk answered, “I am netting the moon.â€
The old monk said, “There is no moon in the pond.â€
The young monk said, “Master old monk, you must forgot to bring your glasses with you, otherwise you would see the moon clearly. I am unable to net the moon because it is moving too fast.â€
The old monk smiled and went back to his room.
