成唯識論述記 2.569

2.569

述曰：謂立量云：諸心、心所非實有性；依他起故；如幻事等，諸部皆許幻事非實。問：若爾，心、境都無差別，何故乃說唯有識耶？

The Commentary states: Formulating the syllogism: All minds and mental factors are not real existent entities; because they arise dependently; like illusory events and the like. All schools accept that illusory events are not real. Question: If so, and mind and object have no difference at all, why then is it said that there is consciousness-only?
