釋禪波羅蜜次第法門 7.40

7.40

受念處有三，謂麁息除故，身心安隱故。六、受喜；七、受樂者，雖有微喜，樂能遍滿身識，既滿，內心喜悅，故名樂；八、受諸心行者，既受樂在懷，必有數法相隨，倚心樂境，故名受諸心行。

"The application of mindfulness to sensations has three, meaning that because coarse breathing is eliminated, body and mind are at ease and secure. (6) Experiencing joy, and (7) experiencing bliss: although there is subtle joy, bliss can suffuse the bodily consciousness; when suffused, the inner mind is joyful, hence it is called 'bliss.' (8) Experiencing mental activities: when bliss is embraced within, there must be mental factors accompanying it, leaning the mind toward the blissful object; hence it is called 'experiencing mental activities.'
