維摩經略疏 5.25

5.25

「佛告摩訶迦旃延」，六、命大迦栴延。文為二：一命問疾、二辭不堪。所以次命者，諸弟子中論義第一。摩訶言大，旃延姓也，從姓立名。又此翻不定，有云肩𠝶、有云文飾，未知孰正。如須陀耶沙彌，八歲論義而得受戒。又如十仙梵志，皆因論義發心入道。故《大經》云「樂論義者生五淨居，即於彼天而般涅槃。」深求其致，乃至成前五種利益，具如身子。

"The Buddha told Mahākātyāyana" is the sixth [section], charging Mahākātyāyana. The text has two [parts]: first, charging him to inquire after the illness; second, declining as incompetent. Why he was charged next is because among the disciples he was foremost in debate. "Mahā" means great. "Kātyāyana" is a clan name, named after the clan. Furthermore, its translation is unfixed: some say "shoulder-hump," some say "literary ornament"; it is unknown which is correct. As with the śrāmaṇera Sudatta, who through debate at the age of eight was able to receive ordination; and as with the ten ṛṣi brahmacārins, who all resolved to enter the Way through debate. Therefore the Mahāparinirvāṇa Sūtra says, "Those who delight in debate are born in the five pure abodes and attain parinirvāṇa in those very heavens." Seeking deeply into its purport, it even accomplishes the aforementioned five kinds of benefit, fully as with Śāriputra.
