俱舍論記 22.74

22.74

「若謂可愛至非可愛故」者，此即牒經部等救。既離染時聖者厭患，可愛復成非愛故，明知樂受無實理成。

As for "If it is said that what is agreeable... because it is not agreeable": this takes up the defence by the Sautrāntikas and others. Since at the time of detachment the noble ones become revulsed, and what was agreeable becomes disagreeable again, it is clear that the proposition that pleasant feeling lacks reality is established.
