俱舍論疏 3.60

3.60

論「樂等五受至依九立三根」，者，後釋五受及三無漏根。受有三種：一攝益、二損惱、三非損非益。又有二種：一身受，謂五識相應；二心受，謂意識相應。身受攝益及第三禪心受攝益名樂受，身受損惱名苦受。心受第二禪已下攝益名喜受，損惱名憂受。通在身、心非損非益名捨受。

Regarding the passage in the treatise, “The five sensations of pleasure and so forth … up to … based on nine, three faculties are established”: This is the second part, explaining the five sensations and the three undefiled faculties. Sensation is of three kinds: first, beneficial; second, harmful; third, neither harmful nor beneficial. Furthermore, there are two kinds: first, bodily sensation, namely, associated with the five consciousnesses; second, mental sensation, namely, associated with the mental consciousness. Bodily sensation that is beneficial and mental sensation in the third dhyāna that is beneficial are called pleasant sensations; bodily sensation that is harmful is called painful sensation. Mental sensation below the second dhyāna that is beneficial is called joy sensation; when harmful, it is called sorrow sensation. That which is present in both body and mind and is neither harmful nor beneficial is called equanimity sensation.
