成唯識論述記 8.316

8.316

述曰：此釋唯業不名為取。世間有情多於現果起執著言，今此是我、我所攝故，即能、所執著名為取。世間有情不多於業起執著故，如有執我而為作者我物等故，前說以取是著義故，不多於業而起於著也。

The Commentary states: This explains why karma alone is not called grasping. Worldly sentient beings mostly give rise to attachment regarding the present fruit, saying: "Now this is grasped as me and what belongs to me"; thus, the grasping subject and the grasped object are named grasping. Worldly sentient beings do not mostly give rise to attachment regarding karma, as in grasping an agent of the self, possessions of the self, and so on; thus, as said before, because grasping has the meaning of attachment, they do not mostly give rise to attachment regarding karma.
