瑜伽師地論略纂 9.50

9.50

The treatise says: "Among the five aspects capable of conforming to the cultivation of impermanence mentioned before, the two aspects of alteration and destruction have already been explained. How does one further contemplate impermanence through the aspect of separation?" At the beginning of the fascicle it was said that one enters the truth of suffering through ten aspects; among the four aspects under suffering, in the first five aspects one enters impermanence. Among these five aspects, the first, the aspect of alteration, is the alterations explained previously through the eight conditions, the fifteen kinds, the sixteen kinds, and so forth; the second, the aspect of destruction, is the aspect of destruction explained previously through inferring that there is momentary arising and ceasing; thus it says, "the two aspects have already been explained."
