成唯識論述記 8.430

8.430

述曰：其不還果生他地，潤生雖不現起愛，然如於彼自身取支定有種故，亦名為定。彼不還者，非但無現愛，亦無現取，取種有故，而得潤生，既取名定，愛例應然，故如彼取，愛定有種。

The Commentary states: When that non-returner is born into another plane, although manifest craving does not arise to moisten rebirth, nevertheless, just as seeds are definitely present for the factor of grasping with respect to his own body, it is also called definite. For that non-returner, not only is manifest craving absent, but manifest grasping is also absent; because seeds of grasping exist, rebirth can be moistened. Since grasping is called definite, craving by analogy should be the same; therefore, like that grasping, craving definitely possesses seeds.
