Which one of these two men is more powerful? Which one is more vulnerable?
While I agree with what they mean, the word "vulnerability" is being used when the author means "openness." Being vulnerable means you are exposed to harm; that a weakness is exposed. Openness means you are unguarded. You can be open and be strong enough to be relatively invulnerable if you are aware of and comforable enough with your own shortcomings that they cannot be used against you to any effect. You cannot be truly vulnerable and be in a position of strength, as these terms are almost mutually exclusive. As such, I suggest mentally replacing each instance of the word "vulnerable" or "vulnerability" with "open" or "openness" in order to make the chapter more palatable.
