A new heart I will give you, and a new spirit I will put within you; and I will remove from your body the heart of stone and give you a heart of flesh.
– Ezekiel 36:26
When the Tin Man asked the Wizard of Oz for a heart, the Wizard gives him a silk heart stuffed with sawdust. The Tin Man then goes on to be ruler of the Winkies (or to incite a mob to attack Elphaba, depending on which version you’re talking about).
What a scary thing it is to desire to be vulnerable. What a courageous thing. No wonder the Tin Man and the Lion are best friends.
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 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.
