Under the perfuming of tathatā, there are three parts: first, stating the number; next, listing the names, which are internal perfuming and external conditions; third, distinguishing their marks. In this third part there are two: first explaining them separately, then explaining them together. In the former there are also two: first, essence and mark; second, the greatness of function. In the former there are also two: first directly revealing it, then removing doubts. In the former, the perfuming is first distinguished.
