5.223

《論》云：而似憂故總說為憂者。問第五《論》云：有分別故憂，無分別故苦，如何得言而似憂故？解云：前分別非分別，且約六識五無六有，相顯故說，於意識中分別意識，得與苦憂俱，俱分別故，相從名憂。

Regarding the statement of the *Śāstra*: "Because it resembles grief, it is collectively spoken of as grief": Question: The fifth [fascicle of the] *Śāstra* states that because there is conceptual discrimination it is grief, and because there is no conceptual discrimination it is pain. How can it be said here, "Because it resembles grief"? The explanation states: The former [distinction between] having discrimination and lacking discrimination was spoken provisionally in terms of the six consciousnesses—the [first] five lacking it and the sixth having it—because their characteristics are obvious. Within the mental consciousness, when mental consciousness conceptually discriminates, it can be concomitant with pain and grief; because both involve conceptual discrimination, by association it is called grief.
