Love and hate are two sides of the same coin. They are not opposites as most people quickly assume. What love and hate have in common is that you care. What is the opposite of caring? Not caring. So the opposite of love is indifference.
They say that sometimes you hate the most the ones you love the most. Sometimes you hurt the most the ones you love the most.
True love is not infatuation. It is not having a crush. It is not some romantic valentine day card sentiment. True love is deep caring which can leave you feeling sweet and in rapture, or bitter and ready to lash out in anger self righteously to offset the terrible shame of being ignored, betrayed, humiliated, rejected, or attacked.
Love makes us grow up. It makes us mature. It makes us rise above ourselves and calls us to become a better person. Mature love is a decision, not a feeling, and we make that decision several times a day, until it becomes a committment that if not honored does more damage to our self than to the other.
Love is the guiding priniciple of life and if, as Socrates suggested, we are to know ourselves, then answer honestly and fearlessly, who and what do you love and are ready to be hurt for?
