法華玄論 2.38

2.38

第十明二說。一者直說、二釋疑成前說。直說者，初段明無九十六種之邪異，亦無五乘之正異，三世諸佛唯有一道也。第二段成前說者，道雖無二，若猶是無常，還同九十六種道，亦還同五乘之道，不名一道。今明九十六道自是無常道，今明一道是常道。五乘之道謂無常道，一乘之道方是常道，故舉常道成前一道也。

The tenth is clarifying the two expositions: first, the direct exposition; second, resolving doubts to establish the former exposition. The direct exposition: the first section clarifies that there is neither the heterodox divergence of the ninety-six kinds nor the orthodox divergence of the five vehicles; all buddhas of the three periods have only the one Path. The second section establishes the former exposition: although the Path has no dual, if it were still impermanent, it would still be identical to the ninety-six kinds of paths, and also identical to the paths of the five vehicles, and could not be named the one Path. What is clarified now is that the ninety-six paths are naturally impermanent paths; what is clarified now is that the one Path is the permanent Path. The paths of the five vehicles are impermanent paths, while only the path of the one vehicle is the permanent Path; hence it adduces the permanent Path to establish the preceding one Path.
