成唯識論述記 10.274

10.274

述曰：「細相現行」，執有生者，以行流轉以生為首，實皆有滅，於有漏有生且舉一生，非不執滅，即執流轉相也。「純作意求無相愚」，即執有滅，即執還滅相也。

The Commentary states: In the 'active manifestation of subtle marks', grasping at arising is because the transmigration of conditioned factors has arising at its head; in reality, they all have cessation. Regarding sāsrava dharmas having arising, arising is provisionally mentioned, but it does not mean cessation is not grasped; this is grasping at the mark of transmigration. The 'delusion of purely intending to seek the markless' is grasping at cessation, which is grasping at the mark of cessation.
