成唯識論述記 2.71

2.71

The Commentary states: Raising the [second] moon as an objection, one should set up the syllogism: Your combined visible matter, even granted to be the object of visual consciousness, is not its condition (thesis); because it completely lacks a real entity (reason); like a second moon (example). The second moon, in their doctrine, is also nominal, does not produce the five consciousnesses, and is cognized solely by mental consciousness. The Ālambanaparīkṣā verse says: 'The combination, with respect to the five consciousnesses, / Granted it is an object, is not a condition; / Because its entity is truly non-existent, / Just like a second moon.' For the Sautrāntika, a second moon is also not an object of the five [consciousnesses]; using it now as an example is intended to take a partial aspect.
