俱舍論頌疏論本 15.62

15.62

上善順非二者，釋不苦不樂受，第三禪上，從第四禪乃至有頂，所有善業名為上善，名順不苦不樂受業。論云：「非此諸業唯感受果，應知亦感彼受資糧，受及資糧此中名受（解云：此相應俱有名資糧也）。」

"Higher wholesome is conducive to neither" explains neither-painful-nor-pleasant feeling: above the third dhyāna, from the fourth dhyāna up to the Peak of Existence (bhavāgra), all wholesome karma is called higher wholesome, and is called karma conducive to neither-painful-nor-pleasant feeling. The treatise says: "It is not that these karmas only bring about the fruit of feeling; it should be known that they also bring about the requisites for that feeling. Both feeling and its requisites are here called 'feeling'. (The commentary explains: What is associated with and co-existent with it is called requisites)."
