楞伽阿跋多羅寶經註解 4.72

4.72

三、以有無二性不可得故，內外俱忘。無外性者是忘外也，無心攝受者是忘內也。內外既忘，則斷一異等見，如是無生即無自性，無性故空，空亦叵得，故曰「非空說空」。空即無生，故又云「無生說空」也。

Third, because the two svabhāvas of existence and nonexistence cannot be apprehended, both internal and external are forgotten. Lacking external svabhāva is forgetting the external; lacking apprehension by the mind is forgetting the internal. Once internal and external are forgotten, views of identity, difference, and so forth are severed. Such non-arising is itself the lack of svabhāva; lacking svabhāva, it is empty; and emptiness also cannot be apprehended, hence it is said, 'it is not on account of emptiness that emptiness is taught.' Emptiness is non-arising, hence he also says, 'on account of non-arising that emptiness is taught.'
