Love is Selfless
But something changed in a moment. In a moment of one fight - in a moment when your anger is ready to kill you and your opponent - and in this moment you suddenly take away your "self" and you feel love and compassion. Love is Selfless. Love is when not your wants, emotions and feelings are in the first place, but others. When you are not "I" but the part of the whole.
Think about this, meditate on love - and take away your "Self" - and find your soul filled with love and compassion.
