Zhu Daosheng, a renowned monk in the late Jin Dynasty, began delivering sermons at the age of 15. By 20, he was lecturing on Buddhism at Mount Lu, establishing himself as a master of Buddhist studies in the Jiangnan region.

He dedicated himself to studying the newly introduced Nirvana Sutra, grasping its profound subtleties. From this, he put forth the theoretical inference that 'everyone can attain Buddhahood,' a view that led to his expulsion from Mount Lu.

He then wandered to Tiger Hill in Suzhou, where he continued to preach, and it is said that even the inanimate rocks would nod in affirmation of his insightful teachings.
