楞伽阿跋多羅寶經註解 4.91

4.91

「彼不生無常者，非常無常，一切法有無不生，分析乃至微塵不可見，是不生義，非生，是名不生無常相。若不覺此者，墮一切外道生無常義。」

"That impermanence of non-origination is not permanence nor impermanence; the existence and nonexistence of all dharmas does not arise, and when analysed even down to subtle particles, they cannot be seen. This is the meaning of non-origination, not origination; this is called the characteristic of the impermanence of non-origination. If one does not awaken to this, one falls into the tīrthikas' meaning of the impermanence of origination."
