注大乘入楞伽經 7.191

7.191

言如來所說不生滅義，不與外道同也，故不生無常生滅論。外道計執一切諸法有實性相，得不生不滅。如來不墮有無品故，凡所說法，離有無生滅也。云何離有無？如幻夢色，正在夢時，不得言無也，然彼色相非實有故，不得言有也，能所見取皆不可得，故說諸法不生不滅，離有離無。

This means that the meaning of non-arising and non-ceasing spoken by the Tathāgata is not the same as that of the non-Buddhists, and therefore does not generate the doctrine of impermanence, arising, and cessation. Non-Buddhists imagine and cling to all phenomena having real intrinsic nature and characteristics, positing them as non-arising and non-ceasing. Because the Tathāgata does not fall into the categories of existence and non-existence, whatever Dharma he expounds is free from existence, non-existence, arising, and cessation. How is it free from existence and non-existence? Like the forms in an illusion or a dream: when right in the dream, one cannot say they do not exist; however, because those forms and characteristics are not truly existent, one cannot say they exist. Neither the grasping nor the grasped can be apprehended; therefore it is said that all phenomena are non-arising and non-ceasing, free from existence and free from non-existence.
