43.70

讚曰。當　太宗朝兩獲瑞石。皆稱趙二十一帝。嘉州之貢猶可以言人為之。至於舒州之獻誌公所記異僧親指。非可言人為也。及誌公降禁中聞寶訓。遣使鐘山奉齋致謝。非聖天子有所誠感曷至於是。

The tribute from Jiazhou might still be called human fabrication, but as for the offering from Shuzhou, with the record of Master Zhi and the personal pointing of the extraordinary monk, it cannot be called human fabrication. And when Master Zhi descended into the imperial palace and his treasured instructions were heard, an envoy was sent to Mount Zhong to offer a vegetarian feast in thanksgiving—if not for the sincere resonance of the sage Son of Heaven, how could it have come to this?
