金光明經文句記 1.87

1.87

二、「而言」下，釋一。即前諦智合一之相也。先簡不合，謂前思後知，此乃覺觀虛妄之心。若智發者，思覺俱寂豁爾開悟，方與諦一，故言一時。四教諦智，一相皆然。

Second, from "and saying" onward, explaining "one." This is precisely the character of the oneness of truth and wisdom mentioned above. First, one excludes what is not united, which refers to earlier thinking and later knowing—these are the delusive minds of vitarka and vicāra. If wisdom arises, both thinking and vitarka become tranquil and one is expansively enlightened, only then becoming one with truth; hence it is called "one time." The oneness of truth and wisdom across the four teachings is entirely like this.
