一、由外緣所生；謂由受用攝受者，過非情順境益五根也。損壞外境界者，過外非情違境損五根也。或由他輩所生損益者，此果一、有情違順二境損益五根；二、由內緣生貪等纏損壞五根，或由等至長養五根；三、由業力令彼五根中途轉變先惡後好等；四、由自體變異，謂彼諸根報及長養互有強弱，自相差別，由四因緣六識生後皆名意根，今此就意識辨意根壞翻之不壞。

First, produced by external conditions: meaning, through enjoying and appropriating, excessive non-sentient favorable objects benefit the five faculties; injuring external objects means excessive non-sentient adverse objects damage the five faculties. Or through benefit and injury produced by other classes: these effects are, first, sentient beings' adverse and favorable objects benefit or injure the five faculties; second, produced by internal conditions, entanglements such as greed injure the five faculties, or meditative attainment nourishes the five faculties; third, through karmic force causing those five faculties to transform halfway, good first and bad later, and so forth; fourth, through transformation of own-substance, meaning retribution and nourishment of those faculties are mutually strong or weak, having distinct individual characteristics. By four causes and conditions, after the six consciousnesses arise, all are called the mental faculty; now here, impaired mental faculty is distinguished with respect to mental consciousness, and its opposite is unimpaired.
