Vulnerability a Spiritual Practice?

I was having a conversation today with a friend/acquaintance about vulnerabilities that we both had.  In sharing each of our most vulnerable moments/fears in life, we realized how much we had in common.

It became a connector for us.  Both afraid to express our vulnerabilities, yet finding that they were the very link between us that will allow us to expand our friendship.  It was an eye-opener for both of us.

I was reminded of this Brene Brown TED Talk and thought it broaches an interesting question:  Is vulnerability a spiritual practice?
