俱舍論疏 3.38

3.38

The Śāstra states: "The distinctions in their characteristics," and below, explains the functions of the remaining faculties. "Their" refers to the above six faculties. It cannot refer to "these sentient beings," because sentient beings have no real entity, having the six āyatanas as their entity. Nor can it be said to refer to "these minds and mental factors," because the sexual distinction between male and female is predominantly physical form. Paramārtha and others state: it refers to these six āyatanas. The distinction of characteristics and the maintenance of life can be understood from the text. "Their becoming defiled is due to the five feeling faculties": defilement is of two kinds: first, being defiled because of association with defilements, which is the mental faculty; second, being defiled because of being bound by being an object of defilements, which applies to all six faculties.
