俱舍論疏 22.44

22.44

The treatise says: "Here, agreeable, up to therefore called suffering"—this explains individually. Here, agreeable contaminated conditioned formations, in conjunction with pleasant feeling, are called the suffering of deterioration (vipariṇāma-duḥkhatā). Disagreeable conditioned formations, in conjunction with unpleasant feeling, are called the suffering of suffering (duḥkha-duḥkhatā). Aside from the conjunction with these two feelings, the remaining contaminated conditioned formations, because of their conjunction with neutral feeling, are called the suffering of conditioned formations (saṃskāra-duḥkhatā).
