注大乘入楞伽經 6.83

6.83

此下大慧舉世俗、第一義二諦，明其設並也。如是者，指世尊上答詞也。謂若如是者，世諦所見，外種種義墮有無相者，即是性離有無，超四句見相者。

From here below, Mahāmati adduces the two truths—conventional and ultimate—to elucidate their parallel standing. "If it is so" refers to the World-Honoured One's preceding reply. It means: if it is so, that which is seen in conventional truth, where the various external objects fall into the marks of existence and non-existence, is itself inherently free from existence and non-existence, transcending the marks of views of the four propositions.
