14.261

第六明二界色差別之相，以三義辨。一、清勝發光；二、非下地境；三、不生苦受。是名色界色中中三義，與此相違。應知即是欲界色中三義。基云：色界色清淨非下眼境者，此據報色任運者，如梵王佛邊聽法，亦變化麁細，令欲界人見等，亦有麁義。

The sixth [section] clarifies the distinctions between the matter of the two realms, distinguishing them by three meanings: 1. It is pure, superior, and radiates light; 2. It is not an object of lower stages; 3. It does not produce painful feelings. These are the three meanings within the matter of the form realm. Those contrary to these, one should know, are the three meanings within the matter of the desire realm. Ji says: Regarding form-realm matter being pure and not an object of lower vision, this is based on retribution-matter that operates spontaneously; as when the Brahmā king listens to the Dharma beside the Buddha, he also transforms between gross and subtle to let people of the desire realm see it, and thus it also has a gross aspect.
