What is Love?

Just A thought

Is love just a human emotion produced by the mind or is it a real unknown thing that causes us to go through unimaginable measures for a certain person or thing.  Can we control this emotion or are we powerless against it?  It gives us a shot of adrenaline in the heart that blinds us from reality.  It's mysterious the way it works and how it can cause us great pain or it can give us life.  But what is truly eerie is that what causes agony and heart ache can also cure us.  Will we one day be able to understand this that makes a huge controversy amoung us. Or will we just develope this sense until it takes over our lives.  Could it be true that it makes the toughest of people change into soft and defenseless beings.  Shall we believe that one day love can save this world from eternal darkness.
