成唯識論述記 2.616

2.616

述曰：釋外法無緣義所由，所執既無，故非緣也，相當情現，如第二月，不遮所緣。外道等徵曰：外色實無，可非內識境；他心實有，寧非內識所緣？又佛他心智能取他心，《二十唯識》說，除佛他心智。不知如佛所行境故，名不如實，即取心外法，如何言心取不離識境？

The Commentary states: This explains the reason why external phenomena lack the meaning of an objective condition. Since what is clung to does not exist, it cannot be an objective condition; its image appears corresponding to sentiment, like a second moon, and we do not bar the perceived object. Non-Buddhists and others challenge: 'If external form is really non-existent, it can indeed not be the object of internal consciousness; but another's mind is really existent, so why would it not be the ālambana of internal consciousness? Furthermore, the Buddha's knowledge of others' minds can apprehend others' minds; the Viṃśikā says: "Except for the Buddha's knowledge of others' minds, because [ordinary beings] do not know the sphere as experienced by the Buddha, it is called not knowing according to reality"—that is, it apprehends phenomena external to the mind. How can it be said that the mind only apprehends objects that are not separate from consciousness?'
