In the book "The Art of Facilitation" there's a really nice definition of empowerment that I'd like to share:

"Empowerment is coming into your own unique place of power where you are truly your own self. It is about recognizing when you are in your power and how you experience this, and bringing it into all aspects of your life. It's all about being at home in your body and in your personal space. It does not always mean being strong and confident - you may be most in your power when you are feeling very vulnerable. It is more to do with being truly authentic and present."
