法華玄論 8.105

8.105

答：此則是開權顯實義。昔說惡道為涅槃，欲引出三界；今指涅槃為惡道，令離二乘，不相違也。又有三句：一惡而非善，謂三百也；二善而非惡，謂度五百也；三亦惡亦善，中間二百能度三界故為善，以是佛道巨患故名為惡。故經云「求二乘者名為不善」，既稱不善，豈非惡道耶？

Answer: This is precisely the meaning of opening the provisional and revealing the real. Formerly, the evil paths were called nirvāṇa in order to guide [them] out of the three realms; now, nirvāṇa is designated an evil path to make them leave the two vehicles. They do not contradict each other. Furthermore, there are three propositions: first, evil and not good, referring to the three hundred [yojanas]; second, good and not evil, referring to crossing over the five hundred [yojanas]; third, both evil and good: the intermediate two hundred [yojanas] can cross over the three realms and are therefore good, but because they are a great affliction to the Buddha path, they are called evil. Hence the sūtra states: 'Seeking the two vehicles is called unwholesome.' Since it is called unwholesome, how could it not be an evil path?
