俱舍論記 22.39

22.39

「此中可意至故名為苦」者，釋下兩句。此諸有漏法中，若可意有漏行法，由與壞苦合，故總名壞苦。諸非可意有漏行法，由與苦苦合，故總名苦苦。除此二種餘有漏行，由與行苦合，故總名行苦。

Regarding "Here, the agreeable... therefore called suffering": this explains the lower two lines. Among these sāsrava phenomena, if they are agreeable conditioned sāsrava phenomena, because they are conjoined with the suffering of change (vipariṇāma-duḥkhatā), they are collectively called the suffering of change. Conditoned sāsrava phenomena that are disagreeable, because they are conjoined with the suffering of pain (duḥkha-duḥkhatā), are collectively called the suffering of pain. Conditioned sāsrava phenomena other than these two, because they are conjoined with the suffering of conditioned existence (saṃskāra-duḥkhatā), are collectively called the suffering of conditioned existence.
