法華玄論 5.12

5.12

有人言：通相之功乃由乎一極，故一為方便之門；級引之功顯彰於三，故三為真實之相。言非三則方便之門得開，悟唯一則真實之相可示。此注解也。

Some say: The efficacy of leading through to marks proceeds from the ultimate one; therefore, the one is the gate to skillful means. The efficacy of gradual guidance is manifested in the three; therefore, the three are the marks of the real. Saying 'not three' allows the gate of skillful means to be opened; realizing 'only one' allows the true mark to be revealed. This is the explanation in the commentary (*Zhu* by Daosheng).
