高僧傳 2.16

2.16

Śramaṇa Daosheng of Longguang had subtle wisdom and penetrating understanding, grasping the profound structure beyond the text; constantly fearing that his words might be mistaken, he entered the passes to seek adjudication. Śramaṇa Huiyuan of Mount Lu had an erudition that encompassed all scriptures, serving as a pillar of the surviving teachings; yet because the time of the Sage was far off, he could not resolve doubtful points, and so sealed his questions in letters to consult Kumārajīva; the details are seen in Huiyuan's biography.
