You Are Also Correct
Two monks who came out of a lecture by their master went on a hot debate regarding what they heard during the lecture. Each of them insited that his understanding was the correct one. To settle the dispute, they went to see the master for a judgement.
After hearing the argument put forth by the first monk, the master said, "You are correct!" The monk was overjoy. Casting a winner's glance at his friend, he left the room.
The second monk was upset and started to pour out what he thought to the master. After he finished, the master looked at him and said, "You are correct, too." Hearing this, the second monk brightened up and went away.
A third monk who was also in the room was greatly puzzled by what he saw. He said to the master, "I am confused, master! Their positions regarding the issue are completely opposite. They can't be both right! How could you say that they are both correct?"
The master smiled as he looked into the eyes of this third monk, "You are also correct!"
