Su Dongpo asked Fo Yin, "What do you see?" Fo Yin replied that he saw the Buddha. Then he asked Su Dongpo what he saw, and Su Dongpo replied that he saw cow dung. When he returned home in triumph and told Su Xiaomei about it, all he could think about was that it was a brilliant victory for him to secretly compete with the monk Fo Yin. You lost badly. Once, two people sat down and looked at each other. Fo Yin has a Buddha in his heart, so what you see in your eyes is a Buddha, and you will see something, Su Xiaomei explained, because you have something in your heart. Su Dongpo was puzzled, but Su Xiaomei shook his head and sighed? What you see is what you think.

Su Dongpo and monk Fo Yin are good friends.
