妙法蓮華經玄義 5.98

5.98

諸經悉有祕密置毒之妙，而未有顯露歷味入妙，亦無顯露決麁即妙。至此《法華》方有二意。同乘寶乘，皆開佛知見，顯露事彰，是故獨稱為妙，其意在此。次第入妙、開麁即妙，各有兩意：按位開入、有增進開入。若言決了聲聞法，是諸經之王，聞已諦思惟，得近無上道，即是按位顯妙。增道損生，即是升進入妙。故《法華》獨稱妙也。

All sūtras possess the wonder of secretly placing poison, but none yet had the explicit entering of the wonderful through traversing the flavors, nor did they have the explicit resolution of the crude into the immediately wonderful. Only reaching this Lotus [Sūtra] are both meanings present. Riding together in the jeweled vehicle, all open the Buddha's knowledge and vision; the explicit matter is manifested, and therefore it alone is called wonderful—the intention lies in this. Entering the wonderful successively and opening the crude to be immediately wonderful each have two meanings: opening and entering according to one's stage, and opening and entering through advancement. If it is said that fully resolving the śrāvaka dharma is the king of all sūtras, and that having heard it and contemplating it with careful discernment, one draws near to the unsurpassed path, this is revealing the wonderful according to one's stage. Advancing on the path and decreasing rebirths is ascending and entering the wonderful. Therefore, the Lotus alone is called wonderful.
