俱舍論疏 2.157

2.157

論「又頗胝迦至云何得見」，識見家重難也。汝前言眼有對故不見障色，水等亦是其障，云何得見？

The *Śāstra* states: "Furthermore, crystal... how can it see?" The proponent of 'consciousness sees' raises another challenge: "You previously said that because the eye possesses resistance (*sapratigha*), it does not see obscured form; but water and the like are also obstructions—how can it see [through them]?"
