第四壽建立中，無色壽命，有倍不倍者，如婆沙八十四卷云：問：何故無色壽量有倍增者有增半者有增少分者耶？答：如異熟因有爾所力還受爾所異熟果故，復次空識無邊處有無邊行相亦有異行相，謂空無邊處無邊行相招萬劫壽，餘行行相亦招萬劫壽，識無邊處無邊行相招二萬劫壽，餘行相亦招二萬劫壽，此上更無無邊行相，唯有異行相，故彼壽量不倍增下。然無所有處別有摧伏我我所等勝善觀行，異於異地，由彼善招二萬劫壽故，餘行相所招壽量亦倍倍增。復次空識無邊處有奢摩他毘鉢舍那，謂空處奢摩他招萬劫壽，毘鉢舍那亦招萬劫壽，識處二行各招二萬壽，此上無勝慧唯有定，故彼壽量不倍增下，餘如前說。

In the fourth, the establishment of lifespan, regarding formless lifespan doubling or not doubling, as the eighty-fourth fascicle of the Vibhāṣā states: Question: Why is it that in the formless [realm] some lifespans double, some increase by half, and some increase by a small fraction? Answer: Just as the cause of maturation has such power, it likewise receives such a maturation fruit. Furthermore, in the sphere of infinite space and the sphere of infinite consciousness, there are limitless modes of activity and there are also different modes of activity: namely, in the sphere of infinite space, the limitless mode of activity incurs a lifespan of ten thousand kalpas, and other modes of activity also incur a lifespan of ten thousand kalpas; in the sphere of infinite consciousness, the limitless mode of activity incurs a lifespan of twenty thousand kalpas, and other modes of activity also incur a lifespan of twenty thousand kalpas. Above this, there are no further limitless modes of activity, but only different modes of activity; therefore their lifespans do not double those below. However, in the sphere of nothingness there is a distinct preeminent, wholesome contemplative practice that subdues 'I' and 'mine' and so on, differing from other stages; because that wholesomeness incurs a lifespan of twenty thousand kalpas, the lifespan incurred by other modes of activity also doubles and redoubles. Furthermore, in the sphere of infinite space and the sphere of infinite consciousness there are śamatha and vipaśyanā: in the sphere of space, śamatha incurs a lifespan of ten thousand kalpas, and vipaśyanā also incurs a lifespan of ten thousand kalpas; in the sphere of consciousness, each of the two practices incurs twenty thousand [kalpas of] lifespan. Above this, there is no preeminent wisdom, but only meditative stabilization; therefore their lifespans do not double those below. The rest is as explained before.
