古樹禪定　釋慧持。廬山遠法師之弟也。當晉隆安二年。辭遠公入蜀。止嘉州龍淵寺。白黑恭敬。陞持之堂者皆號登龍門。至是義熙八年壬子垂誡門徒。遂入定于龍淵龕樹。至宋政和三年風折其樹。持乃出定。徽宗有贊偈三首。見政和年（僧傳并繫年錄）。

Chan Meditation in an Ancient Tree. Shi Huichi was the younger brother of Dharma Master Huiyuan of Mount Lu. In the second year of Long'an of Jin, he took leave of Master Huiyuan and entered Shu, staying at Longyuan Monastery in Jiazhou. Both clergy and laity revered him; those who ascended to Huichi's hall were said to have "ascended the Dragon Gate." Coming to this renzi year, the eighth year of Yixi, he gave his final admonition to his disciples and then entered absorption within a hollow tree at Longyuan. In the third year of Zhenghe of the Song, a wind broke the tree, and only then did Huichi emerge from absorption. Emperor Huizong composed three encomium gāthās for him, found under the Zhenghe era (from the Biographies of Eminent Monks and the Chronological Records).
