A desire is an expectation of things to be different. It denotes a dissatisfaction with the present moment. It means that you know what is best for you. It means that you would like reality to be different. It is a rejection of what is. It is a disturbance. It is a contamination within you created by your own thinking. It takes your attention away from the present moment and into the past or the future. The past is accessed to create a desire for the future. It is a dream, a movie that is being played in your mind. A desire is an idea that has caught hold of you. You are no longer responding to what is but rather to the movie playing in your head. The mind cannot exist without desires, without thinking. Thinking is a sign that there is a desire.
