Many ideas we have about life are simply not true. One of these is that all the space in our heart should be continually filled up with love and happiness. Holding this belief, we may interpret the empty spaces we inevitably discover in our heart as indications that we have somehow taken a wrong turn in our life.
Discovering a 'desert of the heart' is, however, a well-timed spiritual experience - an opportunity to reflect upon the quality of the choices you are making in your life. It is a gift, a chance to rid yourself of something that is causing you and others pain.
