俱舍論疏 3.43

3.43

The Śāstra states: "There are yet other masters who explain the characteristics of the faculties differently." In the following single verse, it thirdly recounts the establishment of the twenty-two faculties by other masters. Because the twenty-two faculties are stated in the sūtras, the various masters make no addition or reduction. The establishment of their number is the intention of the masters of the treatises, which is why the various explanations differ.
