俱舍論疏 2.119

2.119

論「色界至應說自用」，上明根同分、彼同分，自此下明五境同分、彼同分。於中有二：初明五境、次對根顯差別。此即初，文可解。

On the Śāstra's stating, "Visible-form-dhātu [...] should be explained in terms of their own activity": above, the counterparts and non-counterparts of the sense-faculties were explained; from here down, the counterparts and non-counterparts of the five cognitive objects are explained. Therein are two parts: first, explaining the five objects; next, showing their differences in relation to the sense-faculties. This is the first, and the text is easy to understand.
