To love at all

"To 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 entanglement. Lock it up safe in the casket of coffin of you selfishness. But in that casket, safe, dark, motionless, airless, it will change. It will not broken; it will become unbreakable, impenetrable, irredeemable. To love is to be vulnerable."
