Most people mistakenly believe that all you have to do to stop working is not work. The inventors of the Sabbath understood that it was a much more complicated undertaking. You cannot downshift casually and easily. This is why the Puritan and Jewish Sabbaths were so exactingly intentional. The rules did not exist to torture the faithful. They were meant to communicate the insight that interrupting the ceaseless round of striving requires a surprisingly strenuous act of will, one that has to be bolstered by habit as well as by social sanction.
Notice that the more you become a connoisseur of gratitude, the less you are the victim of resentment, depression, and despair. Gratitude will act as an elixir that will gradually dissolve the hard shell of your ego -- your need to possess and control -- and transform you into a generous being. The sense of gratitude produces true spiritual alchemy, makes us magnanimous -- large-souled.
