What is LOVE?

This is the traditional Chinese character for love.

Many of us would believe that we are all capable of loving and being loved in return. According to great scholars there are many different kinds of love. Some would say that love is forever. I just don't understand why sometimes forever could just be for a few days or months. If everyone loves, why is there so much chaos happening around? Is there a kind of love where people would love to see others suffer? Then I can say that love can be just an "idea" where people try to have but not everyone is lucky to receive it. We wanted to believe that love never ends but look at the people around us? Broken marriages, killing, lies, hunger, greed and more... Where's the love that everyone tries to claim that he's capable of giving and receiving? If everyone loves, then peace would not be impossible to attain.. IF ONLY!
