Sympathy can be a synonym for compassion–feeling someone’s pain and wanting to help him. In other words, experiencing deep affinity, so that rather than running from another’s distress, a person can exist with him in a harmony that gives comfort.
Contemporary Buddhist writings and practice emphasize the importance of compassion. Often within that framing of central virtues a person’s compassionate treatment of other people obscures the necessity of compassionately treating oneself.
The first compassion must be for oneself.
