The spiritual life is the uncovering of deeper and deeper levels of joy until that joy that streams from the God-head itself is realized and known in every breath. Every increase in joy is an increase in strength and peace of soul and an increase in all the powers of creativity that reveal life as a divine dance.
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.
