Vulnerability isn't good or bad: it's not what we call a dark emotion, nor is it always a light positive experience. Vulnerability is the core of all emotions and feelings. To feel is to be vulnerable. To believe vulnerability is weakness is to believe that feeling is weakness. To foreclose on our emotional life out of a fear that the costs will be too high is to walk away from the very thing that gives purpose and meaning to living.
