成唯識論演祕 6.17

6.17

A certain opinion says: 'However, saying that apprehending form must depend on light is stated in terms of vases, potsherds, and the like that are obstructed by darkness. In truth, the eye is also able to see dark form; moreover, nocturnal creatures do not depend on light to arise, and aquatic creatures do not wait for space to produce [sight]; furthermore, within obstructed form such as lapis lazuli and sphāṭika, space is also not depended upon, and when the divine eye gives rise to consciousness, it depends on neither space nor light.'
