Yogācāra therefore concludes that we cannot postulate the reality of an external object through direct perception. However since in perceptual cognition we are directly aware of something, there must be an intentional object of the perceptual cognition. That intentional object of perceptual cognition is, according to the Yogācāra, none other than the subliminal impressions (vāsanās) passing from their latent state contained in the storehouse consciousness (ālayavijñāna) to their conscious level.
