"These above...", second, combining them in correspondence with the four enlightenments. Now, these: enlightenment and non-enlightenment, are only set in contrast as true and deluded; forming different approaches, each has four meanings, and thus they are opened to become eight. Now, distinguishing essence and function within each of the true and the deluded, they follow one another in pairs, so there are only four. As in the four sections of the commentary: the first two sections distinguish essence and function with respect to purity. The first section combines two in accord with essence to form original enlightenment. Next, under "Again, because of...", it combines two in accord with function to form actualized enlightenment. The latter two sections under "Again, because of..." distinguish essence and function with respect to defilement. The first section combines two in accord with essence to form fundamental non-enlightenment. Next, under "Again, because of...", it combines two in accord with function to form branch-and-twig non-enlightenment. Therefore, by combining them in pairs, they become defiled and pure, each distinguished into essence and function; thus the previous eight are combined to form four meanings.
