大方廣佛華嚴經隨疏演義鈔 38.67

38.67

疏「後二依二諦說」者，即口業得四十無礙辯才，不出二諦，故彼文云「詞無礙智以世智差別說，樂說無礙智以第一義智善巧說」等。《中論》云「諸佛依二諦，為眾生說法。」

Regarding the commentary's statement, "The latter two are expounded based on the two truths": this refers to attaining the four unhindered eloquence-cognitions of vocal karma, which do not go beyond the two truths. Thus that text states: "Unimpeded cognitive mastery of expression expounds according to worldly cognitive distinctions; unimpeded cognitive mastery of joyful exposition expounds skillfully according to cognition of the ultimate truth", and so forth. The Madhyamakaśāstra states: "The Buddhas teach the Dharma to sentient beings relying on the two truths."
