高僧傳 6.81

6.81

時廬山隱士劉遺民見肇此論，乃歎曰：「不意方袍，復有平叔。」因以呈遠公。遠乃撫机歎曰：「未常有也。」因共披尋翫味，更存往復。

At that time, Liu Yimin, a recluse of Mount Lu, saw this treatise by Sengzhao and sighed, saying: 'I did not imagine that among those who wear square robes there would appear another [He] Pingshu!' He then presented it to Master Huiyuan. Huiyuan tapped his desk and sighed: 'There has never been anything like this!' Thereupon they perused and savoured it together, and engaged in written correspondence.
