Protecting our vulnerability is to be in fear. The need or desire to protect is more often than not an act of fear. If we are not in fear, what would be the need to protect?
As we will open ourselves to love, we will begin to see the benefits and even the excitement of expressing our vulnerabilities whether verbally of through some sort of action.
It really doesn't matter what anyone might think about our vulnerabilities. It only matters what we think about them.
When we operate in love–the love of ourselves in particular–we are willing to express ourselves and our vulnerabilities because in our love we have no fear.
Fear is not the opposite of love, it is the absence of love and this is the primary reason to choose to operate in and from love. It is where we are whole again instead of playing all those parts that involve separation. These are both choices.
