 Yet for Vasubandhu, if the cause cannot be specified, then the person must be conceptually constructed. He adduces the following as an example of conceptual construction: When we see, smell, and taste milk, we have distinct sensory impressions, which are combined in our awareness. The “milk,” then, is a mental construct—a concept built out of discrete sensory impressions. The sensory impressions are real, but the milk is not. In the same way, the “self” is made up of constantly-changing sensory organs, sensory impressions, ideas, and mental events. These separate, momentary elements are real, but their imagined unity—as an enduring “I”—is a false projection.
