Introduction to Shenggong's podium: Shenggong was a famous eminent monk in my country's Jin Dynasty, Zhu Daosheng. At that time, he mainly expounded the Nirvana Sutra and preached that "the sea of suffering is boundless and you can turn back to the shore, put down the butcher's knife and become a Buddha immediately" and "all living beings have Buddha nature." He When he was lecturing in Huqiu, when he said that all evil people can become Buddhas, one of the stones suddenly nodded slightly to him, as if to say, "I understand," and this stone is the nodding stone in the pool. It was a severe winter at that time, but the white lotus flowers in the pool were blooming one after another, and the water in the pool was full. Therefore, there is a saying that "when the old man preaches, the stubborn stone nods, the white lotus flowers bloom".
