楞伽阿跋多羅寶經註解 4.96

4.96

此破外計。佛謂現前所見諸法與無常無異，安有性與事不同耶？故云「非作所作有差別」。故知無常即事、事即無常，此能所不異應是常義。無因性者，《入楞伽》云「不見有因」，言無常無破壞諸法之因。一切性下，佛言諸法滅壞實亦有因，但此意微隱，非凡愚之所能了。

This refutes the external reckoning. The Buddha means: The dharmas visibly perceived before us are non-different from impermanence; how could nature and matter be distinct? Hence it is said: "It is not that maker and what is made have a difference." Therefore we know that impermanence is the matter and the matter is impermanence; this non-difference between agent and object ought to be the meaning of permanence. "Natures without cause": the Ru Lengqie says "not seeing that there is a cause," meaning that impermanence has no cause for destroying all dharmas. Under "That all natures," the Buddha states that the cessation and destruction of all dharmas in fact also has a cause, but this meaning is subtle and hidden, not something that the foolish can understand.
