瑜伽論記 5.244

5.244

數錯亂，謂瞖眩者，於一月處，見多月像者，此中景釋：眼根識同取多月，以是錯亂故非現量，是故五根五識有量非量，不得皆是現量所攝，今解眼識及同緣意識俱取一月而不明了，故後尋求意識錯亂取多月，眼識等雖不明了而實緣一，是故五識但是現量。

Regarding "numerical error, that is, one with visual floaters seeing images of multiple moons in the place of a single moon": herein Jing explains: The eye faculty and eye consciousness together apprehend multiple moons; because this is an error, it is not direct perception. Therefore, among the five faculties and five consciousnesses, there are valid cognitions and non-valid cognitions, and they cannot all be subsumed under direct perception. Now I explain: the eye consciousness and the concurrently cognizing mental consciousness both apprehend a single moon, but unclarifiedly; therefore, the subsequent investigating mental consciousness mistakenly apprehends multiple moons. Although the eye consciousness and so forth are not clear, they actually cognize one; therefore, the five consciousnesses are exclusively direct perception.
