Gratitude is the state of mind of thankfulness. As it is cultivated, we experience an increase in our "sympathetic joy," our happiness at another's happiness. Just as in the cultivation of compassion, we may feel the pain of others, so we may begin to feel their joy as well. And it doesn't stop there.
Stephen LevineThat which is impermanent attracts compassion. That which is not provides wisdom. (116)
Stephen LevineWe are motivated more by aversion to the unpleasant than by a will toward truth, freedom, or healing. We are constantly attempting to escape our life, to avoid rather than enter our pain we, and we wonder why it is so difficult to be fully alive. (43)
