成唯識論演祕 6.184

6.184

詳曰：意云無境而識得生，言無所緣顯境無矣，何繁相言？若言相者而是境相，故須置者四緣之中，亦應說云所緣緣相，相是境故。彼不言相得知是境，故此何須？又相亦名所緣相也。

I examine [this and say]: The intent is that consciousness can arise without an external object; saying "without objective referent" reveals that the object does not exist—why multiply words by adding "aspect"? If you say that "aspect" means the aspect of the object and therefore must be placed there, then among the four conditions one should also say "the aspect of the objective condition," since the aspect is the object. Since that [condition] does not say "aspect" and one knows it is the object, why would it be necessary here? Furthermore, the aspect is also called the aspect of the objective referent.
