In spiritual maturity, the opposite of injustice is not justice, but compassion. Not me against you, not me straightening out the present ill, fighting to gain a just result for myself and others, but compassion, a life that goes against nothing and fulfills everything.
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.
