Love! It's what makes us human. This great quality of civilization is what enables us to create and to care for others. It is not to be confused with lust, crushes, or "puppy love". These are the shadows of what love is and can be. Not love. 

Puppy love and crushes are just being attracted to someone. It can usually be attributed to their outward appearance. A mild and well intended emotion that most teenagers and children share for others. 

Lust is the opposite of love. It is a mindless monster romping through the minds of individuals. Tearing up all images of what is good and how people should be in the minds of the moral, and leaving a smoldering waste product behind of how people should be in the minds of the world: warped, disfigured, stupid, controllable.

Lust is taking and not giving. It is the mauler of marriages, the destroyer of the decent, and the corrupter of love. It's bind is temporal, and it's damage is great

Love is not just wanting to be with them. It's wanting them to be happy. It's not giving them whatever they want, it's giving them what they need (which are two very different things.) 

Love is giving, not taking. It's what makes someone want to take a bullet for another. It's what makes a hungry mother give her child her food. It's what keeps a father who works tirelessly at work to provide for his family. The power that creates honor, order, and law. It is what binds forever.
