楞伽阿跋多羅寶經註解 4.150

4.150

此言如來所證實理本離有無言想，才涉言說分別，則墮二邊之過。分別覺滅者，即言語道斷、心行處滅也。到此乃離諸過，故云「永離常無常」。言非常無常熏者，蓋分別雙非亦是惡見，若離分別，所熏亦離也。

This says that the real principle realized by the Tathāgata is originally free from verbal conceptions of existence and nonexistence; as soon as one touches upon verbal discrimination, one falls into the faults of the two extremes. 'When discriminative awareness is extinguished' means the path of words is cut off and the place of mental activity ceases. Reaching this point, one is free from all faults, hence it says 'forever free from permanence and impermanence.' 'Not perfumed by permanence and impermanence' means that discriminating the double negation is also a bad view; if one is free from discrimination, what is perfumed is also transcended.
