成唯識論述記 2.166

2.166

述曰：第二、申正義也，此解無表如《成業論》末，已下大精稍有差別。謂依思是定、道戒，願謂散無表；或思起願作善惡多，小時節分限；或由異思；或由異緣未起已來，所造善惡時節分限，於此思上假立無表。此即總言，然中有別。

The Commentary states: Second, setting forth the correct doctrine. This explanation of uninformative [karma] is like that at the end of the Karmasiddhiprakaraṇa; below, it is extremely precise with subtle differences. Namely, that which depends on volition refers to the precepts of concentration and of the Path; 'resolution' refers to uninformative [karma] of the diffuse [sphere] (kāmāvacara). Or, volition gives rise to a resolution to perform many good or evil deeds within a small limit of time; or, from another volition, or until another condition arises, regarding the time limit of good or evil deeds performed, an uninformative [karma] is metaphorically established upon this volition. This is the general statement, though within it there are distinctions.
