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 LevineThere is nothing noble about suffering except the love and forgiveness with which we meet it. Many believe that if they are suffering they are closer to God, but I have met very few who could keep their heart open to their suffering enough for that to be true. (124)
