Catharsis is the process of releasing repressed material such as repressed ideas and emotions. Catharsis leads to unconditional acceptance of self.
Mind takes control by splitting away the thoughts and emotions that form the whole of the experience of self. The mind acts as a filter to create the experience of reality, at the comfort level of the person. Thus mind manipulates the sensations to create an experience away from the reality, as it is sensed. When every thought and emotion is accepted and integrated into self, mind stops acting as an agency distorting sensations. It is that pure acceptance of self, is the experience of reality.
