俱舍論記 2.136

2.136

「眼豈如身至無見功能」者，識見家又難。眼若境合，可同身根不取障色。眼根既能取非至境，如何不能見被障色？「頗胝迦」下，引事難見障外色。

"Is the eye like the body […] devoid of the capacity to see?" is another objection by the proponent of consciousness seeing. If the eye contacted its object, it could be like the tactile organ in not grasping obstructed objects. Since the visual organ can grasp objects that have not arrived (aprāpta-viṣaya), how could it be unable to see obstructed forms? From "crystal (sphaṭika)" downward, concrete examples are cited to object regarding seeing forms beyond obstructions.
