大方廣佛華嚴經隨疏演義鈔 76.32

76.32

疏「便有四箇不可說字」者，謂取前例合云不可說不可說，不可說不可說為一不可說不可說轉。上兩不可說不可說是所積之一數，謂一箇不可說不可說。兩箇不可說不可說，乃至不可說不可說箇不可說不可說，故有四箇。今以此又字替却兩箇不可說字，豈非妙耶！所以舉此者，以《刊定記》破經此又字為長故。

Regarding the commentary's "there would be four occurrences of the word ineffable (buke shuo)": taking the earlier pattern, it should say: "an ineffable-ineffable, ineffable-ineffable is one ineffable-ineffable revolution." The first two occurrences of "ineffable-ineffable" are the single unit accumulated—meaning one ineffable-ineffable, two ineffable-ineffables, up to an ineffable-ineffable number of ineffable-ineffables—hence there are four occurrences. Now, replacing two occurrences of "ineffable" with this word "again" (you)—is this not marvelous! The reason this is raised is that the Kanding ji criticized this word "again" in the sūtra as superfluous.
