無色界，八、少分者，謂信等五意命根捨不繫，則三無漏根全，及信等五，喜樂捨意少分，其未知根亦通有漏。今據無漏者，故總云三也。

In the formless realm, parts of eight: the five of faith and so forth, mind, the life faculty, and equanimity are not bound; then all of the three taintless faculties, and parts of the five of faith and so forth, joy, pleasure, equanimity, and mind. The faculty of learning what is not yet known also pertains to the tainted. Now, based on the taintless, it speaks generally of three.
