仁王經疏 3.331

3.331

釋曰：辨第十法師。文別有三：初標位列名、次入位時分、三「常行三空」下辨觀差別。此即標名。玄謂玄遠，達即通達。遠至功用後邊，名之為玄。創入無生忍，名為達也。

Explanation: Explaining the tenth dharma master. The text has three divisions: first, indicating the stage and listing the name; next, the duration of entering the stage; third, explaining the differences of contemplation from 'constantly practicing the three emptinesses' onward. This is the first, indicating the name. 'Profound' (xuan) means deep and far-reaching; 'penetration' (da) means thorough comprehension. Reaching far to the final limit of active effort is called 'profound.' Newly entering anutpattika-dharma-kṣānti is called 'penetration.'
