“Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness that most frightens us. We ask ourselves, Who am I to be brilliant, gorgeous, talented, and fabulous? Actually, who are you not to be? You are a child of God. Your playing small does not serve the world. There is nothing enlightened about shrinking so that other people will not feel insecure around you. We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It is not just in some of us; it is in everyone and as we let our own light shine, we unconsciously give others permission to do the same. As we are liberated from our own fear, our presence automatically liberates others.”

This famous passage from her book is often erroneously attributed to Nelson Mandela.

As honored as I would be had President Mandela quoted my words, indeed he did not. I have no idea where that story came from, but I am gratified that the paragraph has come to mean so much to so many people."

2015, Naturalization Ceremony speech (December 2015)
Context: We celebrate this history, this heritage, as an immigrant nation. And we are strong enough to acknowledge, as painful as it may be, that we haven’t always lived up to our own ideals. We haven’t always lived up to these documents. [... ] We succumbed to fear. We betrayed not only our fellow Americans, but our deepest values. We betrayed these documents. It’s happened before. And the biggest irony of course was -- is that those who betrayed these values were themselves the children of immigrants. How quickly we forget. One generation passes, two generation passes, and suddenly we don’t remember where we came from. And we suggest that somehow there is “us” and there is “them,” not remembering we used to be “them.”
