俱舍論記 22.46

22.46

「如受順受諸行亦然」者，如是三受得三苦名。順受相應、俱有等行，應知亦然說為三苦。故《正理》云「此三苦性其體是何？應定判言三受為體，由三受故。順三受法，如應亦得三苦性名。」

Regarding "As with feeling, the conditioned phenomena concordant with feeling are also like this": just as these three feelings obtain the name of the three sufferings, the conditioned phenomena concordant with feeling—conjoined, coexistent, and so forth—should be known to be likewise spoken of as the three sufferings. Therefore the Nyāyānusāra says: "What is the essence of these three natures of suffering? It should be decisively determined that the three feelings are the essence, because of the three feelings. Phenomena concordant with the three feelings, as appropriate, also obtain the name of the three natures of suffering."
