PRI is based on the premise that we, as adults, often perceive the world through the defense mechanisms that we have developed as children. These defense mechanisms show that we do not have to feel the pain inflicted upon us as children. However, as adults, these defense mechanisms are precisely what make us suffer the most as they give us a distorted perception of the present-day reality. Fear, anxiety, depression, feelings of unworthiness, anger, stress, addiction, eating disorders, and lack of true contact with ourselves and other people are the root cause of our problems in the present.
