注大乘入楞伽經 8.19

8.19

若計物無常性為能生因是有法者，應同所作，性不究竟，自是無常也。自無常故，何能滅壞生起諸法？所無常法皆應是常。何以故？既同所作而計常住自不滅壞，故所作法皆是常也。

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.
