自下第三明界善巧。於中，初結前生後；次正辨界義；後類結同有。就正辨中，初以八門略辨；後以十四門廣辨。前中，初辨八門；復以頌結。

From here on, the third [part] explains skill in the elements (dhātu-kauśalya). Within this, it first concludes the preceding and introduces the following; next, it correctly distinguishes the meaning of element; finally, it analogously concludes their shared existence. Concerning the correct discrimination: first, it briefly discriminates through eight doors; subsequently, it extensively discriminates through fourteen doors. In the first part: it first discriminates the eight doors; again, it concludes with a verse.
