To the degree that each of us is dedicated to wanting there to be peace in the world, then we have to take responsibility when our own hearts and minds harden and close. We have to be brave enough to soften what is rigid, to find the soft spot and play with it. We have to have that kind of courage and take that kind of responsibility. That's the true practice of peace.
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.
