釋禪波羅蜜次第法門 5.145

5.145

答：樂遍身時，身諸毛孔悉皆欣悅。爾時五情雖無外塵發識，而樂法內出，充滿諸根，五根之中，皆悉悅樂，但無外塵對，則不發五識。情依於身，身樂既滿，情得通悅，樂與意識相應，以識內滿故，則遍身而受，所以佛說三禪之樂遍身而受。

Answer: When bliss permeates the body, all the pores of the body rejoice. At that time, although the five sensory faculties do not produce consciousness in response to external dusts, the dharma of bliss emerges from within and fills the faculties; all within the five faculties are delighted and blissful, but without an external sensory object confronting them, the five consciousnesses are not produced. The sensory faculties rely upon the body; since the bodily bliss is full, the sensory faculties attain thorough joy. Bliss is associated with mental consciousness; because consciousness is filled within, it is experienced throughout the entire body. This is why the Buddha taught that the bliss of the third dhyāna is experienced throughout the whole body.
