Four monks decided together to meditate without speaking. By nightfall, the candle flickered and died.
The first monk said, “Oh no, the candle is out.”
The second monk said, “I thought we are not supposed to talk?”
The third monk said, “Why must you two break the silence!”
The fourth monk said, “I’m the only one who didn’t speak.”
One is distracted by the world. One is worried about rules. One is angry with others. One is proud of himself.
Such are the obstacles.
