俱舍論記 3.106

3.106

「無色如前至信等五根」者，可知。若依經部，苦、樂隨身至四定，憂、喜隨心至有頂。彼宗意說：有身即有苦、樂，有心即有憂、喜。

Regarding "The formless realm is as before ... the five faculties beginning with faith": this is readily known. If relying on the Sautrāntikas, pain and pleasure accompany the body up to the fourth dhyāna; grief and joy accompany the mind up to the peak of existence. The meaning intended by their school is: wherever there is a body, there are pain and pleasure; wherever there is a mind, there are grief and joy.
