During the Chuigong period of the Tang Dynasty, Hanshi Shendu from Hangzhou stayed in Lingyin Temple to study. Before leaving, the old monk pointed to the bright lamp in front of the Buddha: "The lamp is there, and the heart is there. If the lamp is not extinguished, don't come back."
He traveled north along the canal to Chang'an and was involved in the power struggle between Prime Minister Pei Yan due to a secret letter from a fellow official. The Pei family used fame as bait to win over him step by step. Shen Du half-heartedly accepted the benefits and reported the news until he found that he had become an accomplice to harm others. He turned back at the edge of the cliff and knelt in front of Di Renjie to confess everything. Three years later, he testified in court, saved the people he had harmed, and was forever owed a life. Finally, he returned to Hangzhou, set up a study hall next to Lingyin Temple, and lit a lamp to light the way for the next person going out.
