"Consciousness is always aware of something. When a patch of azure bursts into our field of awareness, a blip of eye-consciousness sees the color. When a smell wafts toward us, another blip of consciousness knows the scent. Only mind and object; that's all there is to it. Our entire lives are nothing but a chain of moments in which we perceive one sight, taste, smell, touch, sound, feeling, or thought after another. Outside of this process, nothing else happens."
