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 careful round with
hobbies and little luxuries; avoid all entanglements; lock it up safe in a 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,
The only place outside Heaven where you can be perfectly safe from
all the dangers… of love is Hell.
(C.S. Lewis, The Four Loves)
