俱舍論疏 4.85

4.85

論「如身受言故亦無失」，答也。如言身受，非即是身而是心所。言身惛沈，義亦應爾。《正理論》云「𧄼瞢不樂等所生心重性，說名惛沈。由斯覆蔽，心便惛昧無所堪任，瞢憒性故。由是說為輕安所治。」

The treatise says: "Because of expressions like 'bodily feeling', there is also no fault." This is the answer. Just as speaking of 'bodily feeling' does not mean it is the physical body itself, but rather a mental factor, speaking of 'bodily torpor' should be understood in the same way. The Nyāyānusāra says: "The heaviness of mind produced by drowsiness, discontent, and so forth is called torpor. Because of being veiled by this, the mind becomes murky and incompetent, due to its nature of confusion. Therefore, it is said to be counteracted by pliancy."
