俱舍論疏 2.4

2.4

"The treatise says: [...] the rest are said to be invisible." Prose explanation. The three categories in the verse are divided into three sections; this first explains visibility. Both the Vibhāṣā and the Nyāyānusāra provide two explanations. Nyāyānusāra fascicle 4 says: "Why is this said to be visible? Due to two meanings. First, this matter necessarily occurs together with seeing (vision), hence it is called visible. Because matter arises simultaneously with the eye, like having a companion. Second, this matter can be pointed out, hence it is called visible. Because it can be pointed out differently as being here or being there, like having an intentional object. Some say: this matter can produce a reflection in mirrors and the like, hence it is called visible. Because it can be demonstrated like that, and this is also the case. One cannot say that sound has echoes and so forth, so it should also become visible, because they do not arise simultaneously." The Vibhāṣā is the same. This treatise takes only the second, in that it can be pointed out with a distinction of here and there. By this implication, the remaining invisible ones, excluding matter, refer to the other seventeen, which cannot be pointed out with a distinction of here and there, and are called invisible. According to the Nyāyānusāra, lacking the above three meanings is called invisible. Because this treatise is brief, it provides only one explanation.
