Craving can be future-oriented – trying to become successful, powerful, thin, or beautiful; dreaming about being with the perfect partner; worrying about losing your job and so on. It can be fixed on the past, replaying a painful incident over and over again, stirring up old hurts with resentment and revenge, or dwelling on nostalgic replays of the good old days. It takes many shapes and forms but its hallmark is a lack of peace. If our attention is taken up with this energy of dissatisfaction we are not available for spiritual inquiry. As long as we are preoccupied we are distracted by experiences that come and go, preoccupied with changing experiences, preoccupied with being born and dying. This precludes any possibility of noticing deeper realities.
