妙法蓮華經玄義 9.27

9.27

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.
