妙法蓮華經玄義 1.163

1.163

又通作者，四悉檀不同，通是世界悉檀也；四悉遍化眾生，通是為人；四悉檀皆破邪，通是對治；隨聞一種皆能悟道，通是第一義也。

Furthermore, explaining them generally: that the four siddhāntas differ is generally the worldly siddhānta; that the four siddhāntas universally transform sentient beings is generally [the siddhānta] for individuals; that all four siddhāntas shatter heterodoxy is generally the therapeutic [siddhānta]; that according to hearing any one of them one can awaken to the path is generally the supreme-truth [siddhānta].
