俱舍論記 15.146

15.146

「或復此業是樂所受」者，第二釋，約所受釋順樂。果是能受，業因是所受，所受順能受，故名順受。

Regarding "Or, again, this karma is experienced by pleasure," this is the second explanation, which explains 'conducive to pleasure' in terms of what is experienced. The result is that which experiences, and the karmic cause is that which is experienced; what is experienced accords with that which experiences, hence it is called 'conducive to what is experienced.'
