觀音玄義 2.13

2.13

次明普不普者，若凡夫外道見、愛等門，尚不能通出三界，何況普耶？三藏通教雖通化城，亦復非普；別教漸通，亦非普義；唯圓教教觀實相法門能遍十法界，千性相三諦一時圓通，圓通中道，雙照二諦，獨稱為普門也。

Next, to clarify the universal and non-universal: If the gates of views, craving, and so forth of ordinary persons and outsiders cannot even lead out of the three realms, how much less could they be universal? Although the Tripiṭaka and shared teachings lead through to the transformed city, they are also not universal. The distinct teaching leads through gradually, so it is also not the meaning of universal. Only the teaching and contemplation of the true mark dharma-gate of the perfect teaching can pervade the ten dharma-realms: the thousand natures and marks and the three truths simultaneously and perfectly lead through; perfectly penetrating the middle way and doubly illuminating the two truths, it alone is named the universal gate.
