大方廣佛華嚴經隨疏演義鈔 12.10

12.10

疏「權教極果無實事故」者，如有五教，唯圓教中因果俱有實事；前四因中則有，至果皆無，由修權因，若入地後即入實故。猶如百川浩蕩千里，亦無究竟歸處，究竟歸處即是海故。

Regarding the Commentary's stating, "Because the ultimate fruit of the provisional teaching lacks real phenomena": as there are five teachings, only in the Perfect Teaching do both cause and fruit possess real phenomena; in the previous four, they exist in the cause, but when reaching the fruit, they are completely absent, because by cultivating provisional causes, if one enters the grounds, one then enters the real. It is just as hundreds of rivers surge for thousands of miles and also have no ultimate destination of their own, because their ultimate destination is the sea.
