“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 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
I think vulnerability is a tough issue for most people. Nobody wants to be hurt or humiliated but being hurt is part of feeling and feeling is what being alive is all about. It is unrealistic to go through life thinking you cannot get hurt. Anything that causes you joy could also cause you pain, and not necessarily directly. For example, you have a cat that you love, and then it dies. Cats have shorter lives that humans. It's a part of life and we must accept it. That is a simplified example but it gets to the point. I think maybe people get caught up in just feeling good, which isn't a bad thing, I think it's normal but maybe we are raised or socialize to avoid feeling sadness.
"God breaks the heart again and again until it stays open."
-Haziat Inayat Khan
I'm simply writing this to remind us all that pain is a part of life and we should embrace it. The fear of pain causes many people to close their hearts to others or to the world. I guess the fear of pain is in a way a fear of being vulnerable. Put yourself out there with good intentions and experience what the world has to offer you.
