俱舍論疏 22.76

22.76

論「又治苦時至定無實樂」，以治苦故方生樂覺，故離重苦時謂輕苦為樂，實無樂受。第二理也。

On the Śāstra's statement, "Moreover, when remedying suffering... there is definitely no real pleasure": It is only because of remedying suffering that the awareness of pleasure arises; therefore, when departing from heavy suffering, one considers light suffering to be pleasure, while in reality there is no pleasant sensation. This is the second reasoning.
