妙法蓮華經玄義 1.162

1.162

第一義中四者：一切實，乃至四句，是世界；佛、支佛心中所得法豈非理善，是為人；一切語論、一切見、一切著皆可破，一切不能通，第一義能通，是對治；言語道斷，法如涅槃，是第一義。

The four within the supreme-truth [siddhānta]: all being real, down to the four propositions, is the worldly [siddhānta]; that the dharmas attained within the minds of Buddhas and pratyekabuddhas are surely goodness in principle is [the siddhānta] for individuals; that all discussions, all views, and all attachments can be shattered, and while none can penetrate, the supreme truth can penetrate, is the therapeutic [siddhānta]; that the path of speech is cut off and the Dharma is like nirvāṇa is the supreme-truth [siddhānta].
