 For Yogācāra Buddhists, however, sense perception is just as false a “duality” as are false conceptual constructions. Given that the external world must be only mind, the sensory experience that we have of a world “out there” is only a figment of our imagination. The self/other distinction implicit in perception is as much a false imposition as is the self/other distinction implicit in the concept, “self.” Perception, like conceptualization, is only a matter of the mind generating “dual” images. As counterintuitive as this sounds, it may be clarified by analogy to the idea of a multi-player virtual reality game. In a shared virtual reality experience, the first thing the computer system must be able to track is where, objectively, everything is (where the various players are, where the castle with the hidden jewels is, where the dragon is hiding, etc.). Then, when any new player logs in, the system can place that player somewhere in the multi-dimensional, virtual world. At that point, the computer must generate a sensory perspective for that individual. Immediately that person experiences herself to exist in a world of a certain kind, with certain abilities to move around, and fight, and so on. But this is only a trick of the software. The world is unreal, and so is the player’s subjective perspective on that world.
