大方廣佛華嚴經隨疏演義鈔 16.35

16.35

疏「良以體融行」下，三正成前義。言「體融行而因圓」者，行即是因，以體融行，故因行圓滿。「行該真而果滿」者，正成上行融理也。行不該真，何由行得果耶？

Regarding the commentary from "Truly, because essence fuses with practice" downward: third, it directly establishes the preceding meaning. When it says "essence fuses with practice and thus the cause is perfected," practice is the cause; because essence fuses with practice, the causal practice is perfected and complete. When it says "practice pervades the real and thus the fruit is fulfilled," this directly establishes the above [meaning of] practice fusing with principle. If practice did not pervade the real, how could practice attain the fruit?
