10.153

次明修世不可樂想。於中，初先結前生後，下正辨之。辨中有五：初「一切處皆悉具有生老病死」故不可樂；二「一切處無進不退」故不可樂；三「一切世間具受苦樂流轉不定」故不可樂；四「觀世間舍宅」已下，明一切物無不是苦；五「觀世間非歸依處」故不可樂。

Next is the explanation of cultivating the notion of the world as unpleasurable. Therein, first he connects the preceding and introduces what follows, and below directly explains it. In the explanation there are five: First, "In all places there is birth, old age, sickness, and death," and therefore it is unpleasurable. Second, "In all places there is no progress without retreat," and therefore it is unpleasurable. Third, "All worlds fully undergo suffering and pleasure, transmigration being unstable," and therefore it is unpleasurable. Fourth, from "Contemplating worldly houses and dwellings" downward clarifies that of all things, there is none that is not suffering. Fifth, "Contemplating the world as not a place of refuge," and therefore it is unpleasurable.
