大乘百法明門論疏 2.50

Third: concerning 'establishing one kind upon distinctions in the state of nature', the explanation says: "This is the life-faculty. On the basis of the ālaya-vijñāna being capable of sustaining the generic similarity so that the four great elements and the various sense-faculties do not deteriorate, the life-faculty is nominally established upon the citta and caitta-dharmas associated with the ālaya-vijñāna. This is nominally established generally upon citta and caitta-dharmas; in the desire and form realms, it is nominally established generally upon rūpa as well; in the formless realm, it is nominally established solely upon citta and caitta-dharmas."
