注大乘入楞伽經 8.19

8.19

If one imputes that the nature of the impermanence of an entity is an existent entity acting as a productive cause, it should be like what is produced, its nature being non-ultimate and itself impermanent. Since it is itself impermanent, how could it destroy or give rise to all dharmas? All dharmas made impermanent should be permanent. Why is this? Because while being identical with what is produced, it is imputed to be permanent and not itself destroyed; therefore the produced dharmas should all be permanent.
