 It is mental causation, then, that brings about our mental experiences. It is this second level, then, that confirms Vasubandhu as an idealist. Not only the reality that we inhabit (which we ordinarily think of as at least partly non-mental), but also the causal supports upon which such a reality depends, are only mental. Even if the storehouse consciousnesses of living beings provided ongoing support to a real, physical world, we would still want to call that view “idealism” for its insistence on the causal priority of the mental. Since Vasubandhu does not say as much, but instead says that everything that is created by minds is itself mental, we might say that in addition to a causal idealism, Vasubandhu’s is a universal, ontological idealism.
