大方廣佛華嚴經隨疏演義鈔 26.67

26.67

疏「應成四句」者，文出二句。三一因一果，釋文已用。四多因多果，隨修一行無德不招。廣如〈問明〉及〈昇兜率品〉。四句相融，故一一難思。

Regarding the commentary's statement "They should form four propositions," the text brings forth two propositions. The third is "one cause and one result," which has already been used in the explanatory text. The fourth is "many causes and many results": following the cultivation of a single practice, there is no virtue that is not incurred. This is expounded at length in chapters such as "Inquiry and Illumination" and "Ascending to Tuṣita Heaven." The four propositions fuse with one another, and therefore each one is inconceivable.
