詳曰：縱急赤人、人類與德有離、不離，內德不離，外火猛德與類互離。論據外德云互相離，而言亦者，以外離德亦內不離猛赤之德。彼若救云：依內德者，理亦不然，有內無外便無共法。無共法故過同於前，故論不說。

In detailed consideration: Even granting that for an impatient, red-faced person, the human category and qualities have separation and non-separation—the internal qualities are inseparable, whereas the fierce quality of the external fire and the category are mutually separated. The Treatise, relying on the external quality, says "separated from one another"; and the word "also" means that just as the external [fire] is separated from the quality, so the internal is also not inseparable from the quality of fierceness and redness. If they should rescue it by saying: "It is based on the internal quality," this principle is also incorrect: if there is internal but no external, then there is no common dharma. Because there is no common dharma, the fault is the same as before; hence the Treatise does not mention it.
