俱舍論頌疏論本 3.32

3.32

"As is mental pleasure in the third dhyāna" means: "mind" refers to the sixth, the mental consciousness. In this third dhyāna, feeling associated with the mind that can comfort and benefit is also called the pleasure faculty. That is to say, in the third dhyāna, because the five sense-consciousnesses are absent, there is no physical feeling of pleasure; solely mental pleasure is called pleasure (sukha).
