注大乘入楞伽經 8.13

8.13

此下如來正破彼計也。謂現見物無常，與所作諸法無有異體，故云無有能作所作差別。既云此是物無常、此是所作法，無差別故，能作所作應俱是常。何以故？不見有物無常為因，而能破壞所作諸法成於無故。

From here onward, the Tathāgata directly refutes their assertion. It means that visibly observed impermanence of an entity and the produced dharmas have no different substance; hence it says there is no distinction between producer and produced. Since they say, 'this is the impermanence of the entity, this is the produced dharma,' and because there is no distinction, the producer and produced should both be permanent. Why is this? Because one does not see the impermanence of an entity acting as a cause that can destroy produced dharmas and bring them to non-existence.
