俱舍論疏 2.212

2.212

論「眼耳不定至小大等量」，此辨眼、耳取境大小不定。此亦說所依之根與境大小不等，非是要如蒲桃果也。如半蒲桃果，眼取蒲桃境亦名取大。言「蚊雲等聲」者，隨質判也。

The passage in the treatise from 'Eye and ear are not fixed' up to 'equal size to small or large' distinguishes that the eye and ear grasp objects of unfixed size. This also says that the supporting faculty and the object are not equal in size; it does not mean that it must be like a grape. Just as with half a grape, an eye grasping the object of a [whole] grape is also called grasping something large. Saying 'the sounds of mosquitoes, clouds, and so on' is judged according to the physical substance.
