Shishuang Qingzhu

Shishuang Qingzhu was a student of Daowu Yuanzhi who established a remarkable community on Mount Shishuang, known as the "dead tree hall" because its members practiced sitting meditation with such radical stillness that they appeared as lifeless as withered trees. This practice of utter non-engagement with thought and sensation was Shishuang's distinctive contribution to Chan methodology—a form of sitting so absolute that it preceded the later Caodong emphasis on silent illumination.

Shishuang's famous instruction was: "Cease and desist. Be like a censer in an ancient temple, like a length of white silk." This teaching of radical cessation—not as torpor but as the complete dropping of the discriminating mind—became foundational for the Caodong tradition. When he died, his community was so devoted to this practice that a succession crisis arose because no student would presume to claim the teacher's role. His student Jiufeng Daoqian eventually maintained the lineage.
