大方廣佛華嚴經隨疏演義鈔 33.77

33.77

第六正教甚深。疏「一對初義」者，謂約一人豎論。教能斷惑亦見，即合斷惑，何以久而不斷？「二對後義」，後義約多人橫說，同見斷惑，佛教是一，何以一斷一不斷耶？悉者，俱合斷故。

Sixth, the profundity of the correct teaching. Regarding the commentary's statement, "First, responding to the first meaning": this discusses vertically with respect to a single person. Since the teaching can sever delusion and one has also seen it, one ought to sever delusion; why then does one go long without severing it? "Second, responding to the second meaning": the second meaning speaks horizontally with respect to many people. If they equally see and sever delusion, and the Buddha's teaching is one, why does one sever it while another does not? The word "all" means that both ought to sever it.
