3.88

若成就樂、身，各定成就四者，謂成就樂根時，必有命、意、捨也。若成身根時，亦必有命、意、捨，故言各也。成樂不成身者，謂聖者生無色界，無色界中成就下三禪無漏樂根也。成就身不成樂者，謂異生生第四禪，彼無樂根，下三禪樂根彼已斷也，既是凡夫，不可成就下無漏樂故，不成樂根而成身根也。成樂不成喜者，謂異生生第三定也。

"If possessing pleasure or body, each definitely possesses four" means that when possessing the pleasure faculty, there must be life, mind, and equanimity. When possessing the body faculty, there also must be life, mind, and equanimity; hence it says "each." As for possessing pleasure without possessing body, this refers to a noble one born in the formless realm: in the formless realm, one possesses the untainted pleasure faculty of the lower three dhyānas. As for possessing body without possessing pleasure, this refers to an ordinary person born in the fourth dhyāna: that realm lacks the pleasure faculty, and the pleasure faculties of the lower three dhyānas have already been severed by them; since they are an ordinary person, they cannot possess the lower untainted pleasure, and therefore they do not possess the pleasure faculty but do possess the body faculty. As for possessing pleasure without possessing joy, this refers to an ordinary person born in the third dhyāna.
