"To love at all is to be vulnerable. Love anything, and your heart will certainly be wrung and possibly broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even to an animal. Wrap it up careful 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, motion-less air - it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable… The only place outside Heaven where you can be perfectly safe from all the dangers of love… is Hell."
