Regarding the heading "actualized enlightenment": it can also be that earlier it briefly clarified the essence of actualized enlightenment, now it extensively clarifies the marks of actualized enlightenment, and later the actualized not being different from the original concludes the marks into identity with the essence. First, identifying cause and fruit. Regarding the commentary's "defiled mind": that is, the six defiled minds. "Nature-pure" is the tathāgatagarbha. Because defiling the pure forms defilement, the pure is called the source of defilement; hence the text below states: "This mind is from the very beginning pure in its own nature, yet ignorance exists; being defiled by ignorance, it has its defiled mind." "Coarse marks" refers to the marks of transformation and manifestation, together with the six coarse marks and so forth. Transformation and manifestation are also the coarse within the subtle, and are all coarse marks. The mark of arising is the karma mark, the subtlest among the deluded; because the coarse arises from the subtle, the subtle is called the source of the coarse. Hence the text below states: "The subtle within the coarse and the coarse within the subtle are the realm of bodhisattvas; the subtle within the subtle is the realm of buddhas."
