"You may think it is disloyal to be happy when others are sad, healthy when they are ailing, or loved when they are lonely. And the more sympathetic you are, the more likely you'll feel as bad as the person you are trying to help. Unfortunately, that's like seeing an accident victim bleed out, then grabbing knife and opening your own veins.
There's a passage by Persian mystic Hafiz that reads, 'Troubled?/Then stay with me, for I'm not." The best thing you can do for any troubled person is to become untroubled yourself. If I come to you with a broken heart and you feel sad for me, your job is not to stop my pain, but to return to happiness in yourself. Instead of trying to feel better by fixing me, just feel better. This will give me the environment I need to solve my own problems. Everyone in distress just wants to walk beside still waters."
