8.164

餘空門，亦空亦有門，非空非有門，入實之觀，例亦為十。諸門方便，雖各不同，俱會圓真，理無差二，三門觀法，準有可知，不復委記（云云）。

The contemplations of entering reality through the remaining gate of emptiness, gate of both emptiness and existence, and gate of neither emptiness nor existence likewise comprise ten points. Although the expedients of the various gates each differ, they all converge in the perfect truth; in principle there is no discrepancy or duality. The contemplation methods of the [other] three gates can be understood by analogy with [the gate of] existence, and will not be recorded in detail again (and so forth).
