注大乘入楞伽經 8.81

8.81

若言如來是無常，即同瓶衣一切作法無常過也，所修正因福慧莊嚴，皆空無益。然佛如來功流萬世常存，道通億劫彌固。又一切世間有所作法，皆應是如來，以同是作因生故。而言如來是常無常者，有如上過，故不可言說也。

If one were to state that the Tathāgata is impermanent, that would entail the fault of being impermanent like jars, garments, and all created phenomena; the proper causes practiced—the adornments of merit and wisdom—would all be empty and futile. Yet the Buddha, the Tathāgata's merit flows across ten thousand generations and perpetually endures; his path penetrates a hundred million kalpas and remains ever firmer. Furthermore, all fabricated phenomena in the world would have to be the Tathāgata, because they would equally arise from created causes. Yet to assert that the Tathāgata is permanent or impermanent incurs the faults mentioned above, and therefore it cannot be expressed in words.
