There are twenty-two faculties (Tib. དབང་པོ་, Skt. indriya) according to Mipham’s Khenjuk:
1-6) The six of the eye faculty, ear faculty, nose faculty, tongue faculty, body faculty the mind faculty. These six control the apprehending of their individual objects.
7) The life faculty controls the remaining in a similar class [of sentient beings].
8-9) The male and female faculties form the respective physical supports [for being male or female] and control the unbroken continuity of births from a womb.
10-14) The five faculties of the sensations of pleasure, pain, mental pleasure, mental pain, and of neutral sensation control the experiences of the fully ripened results [of karma].
15-19) The five faculties of faith, diligence, recollection, concentration, and discrimination control the mundane virtues or the purity [of detachment].
20-22) The faculties of 'making all understood', of 'understanding all,' and of ‘having understood all' consist of faith and so forth in the stream-of-being of, [respectively, someone on the paths of] seeing, cultivation, and no-training. They control the supramundane purities [of noble beings].
Faculties are therefore called controlling faculties.
