In ancient times itinerant Zen monks when arriving at a monastery could challenge the monks to a theological contest and would be given food and shelter if they won but would have to move on if they lost. There was a monastery occupied by two brothers, one was wise and the other foolish. The foolish monk had but one eye. One night it was raining cats and dogs and an itinerant monk knocked on the door. The wise brother wishing to be kind to the drenched fellow suggested he has a contest with his brother. Within minutes the contest was over. The travelling monk entered the room, bowed and admitted defeat. The wise brother asked: “Tell me what happened?” The other replied: “Your brother is a genius. We decided to debate in silence. I went first and showed a single finger signifying the Buddha. Your brother showed two fingers, meaning the Buddha and his teachings. I replied with three fingers, indicating the Buddha, dharma and the sangha. Your brother replied with coup de gras when he showed me his fist proving that in reality the Buddha, the dharma and the sangha are all one.” The poor monk left in the stormy night. Just then the brother stormed in, angry. “That man was so rude.” “What happened?” The one-eyed brother replied: “We decided to have a silent debate and the first thing he did was to put a single finger up meaning, ‘I see you have only one eye.’ So I put up two fingers out of courtesy to him, meaning, ‘I see you have two eyes.’ But the guy was so rude, he put up three fingers telling me that together the two of us have three eyes. I got so mad, I shook my fist at him, telling him, ‘If you don’t stop talking about eyes, I’m going to punch your lights out.”
