仁王經疏 3.158

3.158

Explanation: Second is the impurity of the faculties. This means that among the twenty-two faculties, one further contemplates fourteen faculties as impure. Namely, the five faculties of the eye and so forth possess the sentiment of the five consciousnesses, or alternatively are categorized as sentient, and are called the five sentimental faculties; the five feeling faculties are suffering, pleasure, grief, joy, and equanimity; together with the male, female, mental, and life faculties, all of these are defiled and possess boundless faults, so the fourteen are all spoken of as impure. The five faculties of faith and so forth and the three undefiled faculties are exclusively of a virtuous nature and are not spoken of among the faults; therefore, when the practitioner of contemplation contemplates the fourteen faculties, he immediately gives rise to the supreme mind of awakening.
