Dissatisfaction and hope
People claim "spiritual dissatisfaction" when material wealth fails to satisfy. Correctly, it is emotional dissatisfaction; why drag the word "spiritual" into the ugly affair? How often heart is mistaken for spirit!
Such "spirituality" can always be traced back to the need for hope - a need for a satisfying dream of the future. As long as there is the slightest hope of happiness, there is fuel for fantasy. Fantasy is called "spiritual" because it is altogether beyond this world. Being purely imaginary it is naturally beyond this world.
Hope is the psychological remedy to every disease. One sick with cancer is encouraged to remain hopeful of remission. The abandoned lover is told to remain hopeful that such a special love will come again. The ironic thing is, the more hope we have, the more hopeless our situation becomes.
