法華玄論 1.90

1.90

答：乘若有三，可有三性；既唯有一乘，則唯有一性。如《毘婆娑》云「一切眾生有三乘性，隨成一乘則餘二非數緣滅。」法華明一乘，義則不然，故唯有一乘、唯有一性。

Answer: If the vehicles were three, there could be three natures; since there is only the one vehicle, there is only the one nature. As the Vibhāṣā says: 'All sentient beings have the nature of the three vehicles; whenever one vehicle is attained, the other two undergo non-analytical cessation.' When the Lotus clarifies the one vehicle, the principle is not so; therefore, there is only the one vehicle and only the one nature.
