成唯識論述記 4.535

4.535

述曰：第四比量難也。所說五位無心位中，定實有識；具根、壽、煖有情攝故；如有心位。具根、壽、煖言，引經具證也。

The Commentary states: The fourth is an objection by inference. In the stated five mindless states, there is definitely and truly consciousness; because they possess faculties, lifespan, and warmth, and are subsumed under sentient beings; like states with mind. The phrase "possess faculties, lifespan, and warmth" cites the sūtra as complete proof.
