成唯識論述記 10.46

10.46

述曰：相者，有相；用者，功用。無性云：一切有相，一切加行，皆不能動此地心故。第七地雖一切相不能動之不現行故，然不自在任運而轉，有加行故，猶有煩惱；第八地中任運而轉，不依加行，無功用故，亦無煩惱，七、八二地之差別也。《十地》云：「報行純熟，無相無間，故名不動」，此地已去明知無相，非有間也。

The Commentary states: "Marks" refers to having marks; "application" refers to effort. Asvabhāva says: It is because all that has marks and all preparatory applications are unable to move the mind of this ground. Although in the seventh ground all marks are unable to move it because they do not become active, nevertheless it does not operate spontaneously at will, and because there is preparatory application, there are still afflictions. In the eighth ground it operates spontaneously at will, does not rely on preparatory application, and because there is no effort, there are also no afflictions—this is the distinction between the seventh and eighth grounds. The Daśabhūmika says: "The actions of karmic retribution are fully matured; it is signless and uninterrupted, and is therefore called 'Immovable'." From this ground onward, know clearly that it is signless and not interrupted.
