妙法蓮華經玄義 9.27

9.27

融門四相，今當說。若言「佛之智慧微妙第一」，又云：「我以如來智慧觀彼久遠猶若今也」。智知妙法，有門也。一切法空，常寂滅相，終歸於空，空門也。諸法常無性，佛種從緣起，即亦空亦有門也。非如非異，非虛非實，雙非兩捨，即非空非有門也。

The four characteristics of the interfused gates shall now be explained. If it says, 'The Buddha's wisdom is subtle, wondrous, and supreme,' and further says, 'With the Tathāgata's wisdom, I contemplate that remote past just like today'—wisdom knowing the wondrous Dharma is the gate of existence. All dharmas are empty, constantly bearing the mark of tranquility and extinction, ultimately returning to emptiness—this is the gate of emptiness. All dharmas are permanently devoid of nature, and the buddha-seed arises from conditions—this is the gate of both emptiness and existence. Neither such nor different, neither unreal nor real, doubly negating and setting aside both—this is the gate of neither emptiness nor existence.
