妙法蓮華經玄義 10.174

10.174

彼經復明：四論、四法、四境界、四門、四斷煩惱智、四苦、四集、四道，皆與四教相應，具如彼應知。

That sūtra further explains: the four treatises, four dharmas, four spheres, four gates, four knowledges that sever afflictions, four sufferings, four origins of suffering, and four paths—all correspond to the four teachings, and should be understood as fully set forth therein.
