法華玄論 7.182

7.182

答：二乘正謂是果而非道。今斥其病，故云是道非果。道者因義也，汝等所行若因若果皆是菩薩家道耳。

Answer: The two vehicles precisely thought that it was the fruit and not the path. Now rebuking their sickness, it is said to be the path and not the fruit. "Path" has the meaning of cause; whether cause or fruit, what you are practicing is all simply the path of the bodhisattva family.
