There is a Buddha in the heart, and people are Buddhas; If you have shit in your heart, it's shit to look at people. This is a story between Su Shi, a famous person in Song Dynasty, and Fo Yin, a Zen master of Jinshan Temple. One day, Su Shi meditated with the Zen master. Su Shi asked the Zen master, "How is my meditation posture?" ? The other party replied: very good, like a Buddha. The Zen master asked Su Shi | "How is my posture?" Su Shi replied ridiculously, "You are like a lump of cow dung." The Zen master smiled without a word, and later told his sister Su Xiaomei. My sister said that you lost, and the Zen master was like a Buddha, so he thought you were like a Buddha, and your heart was like cow dung, so you thought the Zen master was cow dung.
