Hong Ren, the fifth ancestor, chose his successor, summoned all the monks in one day, and told them the essence of Prajna Paramita, so that their disciples could make their own judgments. If they realize the general idea, they may be the sixth generation ancestors. Sometimes, the seated monk is beautiful and knowledgeable, so just think about it and write it on the corridor wall. He said: "I am a bodhi tree, and my heart is like a mirror." Always try Buddha, don't be dust. " Huineng listened and asked who wrote the sentence. Someone told him. After hearing this, Huineng said, "Beauty is beautiful, but it is gone." Disciples laughed at it, it was superficial. Huineng was not surprised, saying that I also had a poem, so he asked someone to write a book next to Shen Xiu's poem at night. He said: "Bodhi has no trees, and the mirror is not a stage. There is nothing, so there is no dust. " Everyone was surprised and said what they said. It's amazing that you can't judge a book by its cover. Seeing that everyone was surprised, Wu Zu was afraid that people would harm Huineng, so he wiped Huineng's poems off with his shoes and deliberately said, "I've never seen sex before." Everyone thinks so.
