成唯識論述記 5.890

5.890

述曰：一云，若憂根、苦根皆能引無漏，無漏所引皆通無漏。受寬根狹，故論說苦受通無漏。一云，五根中，唯以苦根於學、無學身中，無漏第六意引生故。或唯後得智中方起，五識精進等故，有苦根，假名無漏。然五十七說是無漏，何以知者？彼漏、無漏門作是說故。此苦雖然憂，非無漏，雖亦能為無漏加行，仍為未知欲知根性，非無漏引生，不俱起故，非無漏攝。

The Commentary states: One says: If both the faculty of grief and the faculty of pain can induce the uncontaminated, whatever is induced by the uncontaminated is entirely uncontaminated. Feeling is broad and faculty is narrow; therefore the treatise states that painful feeling extends to the uncontaminated. Another says: Among the five faculties, only the faculty of pain in the bodies of those in training and those beyond training is induced and generated by the uncontaminated sixth mental consciousness. Or it arises only within post-attainment wisdom, where due to the vigor of the five consciousnesses, the faculty of pain exists and is nominally called uncontaminated. However, [fascicle] fifty-seven states that it is uncontaminated. How is this known? Because it is stated thus in the gate of contaminated and uncontaminated. Although this pain is [associated with] grief, it is not uncontaminated; although it can also serve as the preparatory practice for the uncontaminated, it remains of the nature of the faculty of the desire to know what is not yet known, is not induced and generated by the uncontaminated, and does not arise together with it, so it is not subsumed under the uncontaminated.
