A spiteful or hateful action directed toward another person merely mirrors our own feelings about ourselves. No one tries to hurt another when feeling good about his or her own self. Such actions stem from feelings of frustration, anger, or distress, whether recognized or not. All such negatives result from fear, manifest as low self esteem, low self respect and low self love.
The love we feel for ourselves determines and limits the amount of love we can feel for others. One person cannot love another to a greater degree than the person loves his or her self.
If we wish to live with love, we must recognize love when we see it and recognize what is not love: that is, evil. Learn to recognize evil in all its manifestations, that you might counter it with its antithesis, which is love, because the cause of evil is an absence of love.
