答：無生門亦攝諸門，諸門亦攝無生門。欲依智德義便，故言無生門。此應四句：生門、無生門、亦生亦無生門、非生非無生門。一一門各有四門，四四十六門。若依斷德義便，應有滅門、不滅門、亦滅亦不滅門、非滅非不滅門。一一門各有四門，四四十六門。合三十二門。《大經》舉十五日月光增，正喻智德；十六日月光減，正喻斷德。月無增、無減，約白論增，約黑論減。實相無智、無斷，約照論智，約寂論斷。若無生門攝一切法高極，此竪攝一切法也。若無生門攝諸法廣遍者，即無生門橫攝一切法也。

Answer: The gate of nonproduction also subsumes the other gates, and the other gates also subsume the gate of nonproduction. Wishing to rely on the convenience of the meaning of the virtue of wisdom, it is called the gate of nonproduction. Here there should be four phrases: the gate of production, the gate of nonproduction, the gate of both production and nonproduction, and the gate of neither production nor nonproduction. Each gate has four gates, making four times four, sixteen gates. If relying on the convenience of the meaning of the virtue of eradication, there should be the gate of cessation, the gate of non-cessation, the gate of both cessation and non-cessation, and the gate of neither cessation nor non-cessation. Each gate has four gates, making four times four, sixteen gates. Combined, there are thirty-two gates. The Great Scripture cites the waxing of the moonlight on the fifteenth day precisely as an analogy for the virtue of wisdom, and the waning of the moonlight on the sixteenth day precisely as an analogy for the virtue of eradication. The moon has neither waxing nor waning; in terms of the bright fortnight we speak of waxing, and in terms of the dark fortnight we speak of waning. True reality has neither wisdom nor eradication; in terms of illumination we speak of wisdom, and in terms of quiescence we speak of eradication. If the gate of nonproduction subsumes all dharmas to their supreme height, this is vertical subsumption of all dharmas. If the gate of nonproduction subsumes all dharmas in their vast ubiquity, this is horizontal subsumption of all dharmas by the gate of nonproduction.
