The action of Pity leaps quicker than light from the highest place to the lowest to bring healing and joy, whatever the cost to itself. It changes darkness into light and evil into good. But it will not, at the cunning tears of Hell, impose on good the tyranny of evil. Every disease that submits to a cure shall be cured: but we will not call blue yellow to please those who insist on having jaundice, nor make a midden of the world's garden for the sake of some who cannot abide the smell of roses.
C. S. LewisTo love at all is to be vulnerable. Love anything and your heart will be wrung and possibly broken. If you want to make sure of keeping it intact you must give it to no one, not even an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements. Lock it up safe in the casket or coffin of your selfishness. But in that casket, safe, dark, motionless, airless, it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. To love is to be vulnerable.
C. S. Lewis
