金光明經文句記 2.74

2.74

初、總標心口。圓人根利，聞空有等皆知性具，性具四門豈有隔礙？一門具三，三門皆爾。稱性而觀，稱性而說，既皆稱性，性絕言思，故觀即無觀、說即無說，是故觀說皆云如實。

First, generally indicating the mind and the mouth. Those of the perfect [teaching] have sharp faculties; hearing of emptiness, existence, and so forth, they all know they are inherently entailed in the nature. How could the four gates inherently entailed in the nature be obstructed? One gate entails the other three, and the three gates are likewise. Contemplating in accordance with the nature and preaching in accordance with the nature—since both accord with the nature, and the nature transcends speech and thought, contemplation is non-contemplation, and preaching is non-preaching; therefore both contemplation and preaching are said to be "in accordance with reality."
