出三藏記集 12.9

12.9

魏祖答孔是知英人開尊道之情習生貽安則見令主弘信法之心。所以有取二書指存兩事。又支遁敷翰遠國述江南僧業故兼錄。

The Founder of Wei's reply to Kong shows that a brilliant man opened his heart to honor the Dao; Xi Sheng's letter to Dao'an reveals that a fine ruler propagated the mind of faith in the Dharma. For this reason, these two letters are adopted, their purports preserving the two matters. Furthermore, Zhi Dun sent correspondence to a distant land recounting the monastic deeds south of the Yangtze; thus it is also included.
