Consider that not only do negative thoughts and emotions destroy our experience of peace, they also undermine our health.
Dalai LamaThe simple recognition that everyone else wants to be happy and not to suffer, just as I do, serves as a constant reminder against selfishness and partiality. It reminds us there is little to be gained from being kind and generous while hoping to win something in return. Actions motivated by a desire to earn a good name for ourselves are still selfish, even if they appear to be acts of kindness.
