We have to heal our wounded world. The chaos, despair, and senseless destruction we see today are a result of the alienation that people feel from each other and their environment.
We are not enemies, but friends. We must not be enemies. Though passion may have strained, it must not break our bonds of affection. The mystic chords of memory will swell when again touched, as surely they will be, by the better angels of our nature.
We need more light about each other. Light creates understanding, understanding creates love, love creates patience, and patience creates unity.
To live alone is the fate of all great souls.
