The most important form of distortion fundamental to the way our minds operate has to do with creating the notion of self out of what is essentially an impersonal process. Selfhood is the expression of a particular kind of distortion of view, a situation that develops gradually from basic misperceptions, to the casting of whole sets of misinformed thoughts, and eventually to a deeply rooted belief system that becomes imposed upon all further perception and thought. Here again we see a cyclical pattern. Perceptions give rise to thoughts, which congeal into beliefs, and which then influence perception. When the system operates optimally, it allows for growth, learning, and transformation. But when it is fundamentally misinformed, it can also give rise to a considerable amount of delusion. Trouble arises when the constructed self becomes the main organizing principle, when it is unrealistically invested with qualities it does not innately possess, and, most importantly, when it becomes the node around which maladaptive behaviors coalesce. The self comes to be experienced as a central and dominant element of psychic life, mistaking what is a series of contingent patterns in constant flux for an enduring entity.
