大般涅槃經集解 68.38

68.38

案僧亮曰：有為羸劣名乏，六道差別名道。八道從所斷得名也。寶亮曰：此言乏道，唯生死是。乏道能不息一切煩惱果報。具八聖道，德行盈滿，業累消盡，名沙門果也。

Sengliang notes: The saṃskṛta is frail and deficient, hence called 'destitute'; the distinctions among the six destinies are called 'paths'. The eightfold path gets its name from what it cuts off. Baoliang says: What is here called the destitute path refers solely to saṃsāra. The destitute path is unable to bring to rest all defilements and retributions. Endowed with the eight noble paths, one's virtuous practice is full and karmic encumbrances are exhausted; this is called the fruit of a śramaṇa.
