Perception is reality

Why does the pasuk of Tzitzis put the heart before the eyes, when Rashi says the eye sees first, then the heart wants, then the body sins? The backwards order says something about how the Meraglim saw the land, and about how any of us sees. A teacher walks into class late, and a girl in the front points at her watch. The teacher is furious and throws her out in front of everyone. The next day, the girl's mother comes in with an explanation that changes the whole scene. What the teacher saw was real to her, but was it what happened?
