"All of us live at the feeling level, and our feelings are in large part a result of the way we perceive things. You observe or are told something, you interpret it, and only then do you have a reaction at the feeling level. The point is that feeling is preceded by perception, and all of us are capable of controlling our interpretation [the associations and assumptions] of what we see. If we can control our interpretation, then it logically follows that we can exercise some control over our feelings as well."
