“Harry Dresden: There’s power in the night. There’s terror in the darkness. Despite all our accumulated history, learning, and experience, we remember. We remember times when we were too small to reach the light switch on the wall, and when the darkness itself was enough to make us cry out in fear. Get a good ways out from civilization-say, miles and miles away on a lightless lake-and the darkness is there, waiting. Twilight means more than just time to call the children in from playing outside. Fading light means more than just the end of another day. Night is when terrible things emerge from their sleep and seek soft flesh and hot blood. Night is when unseen beings with no regard for what our people have built and no place in what we have deemed the natural order look in at our world from outside, and think dark and alien thoughts. And sometimes, just sometimes, they do things.”

Context: One might compare the journey of the soul to mystical union, by way of pure faith, to the journey of a car on a dark highway. The only way the driver can keep to the road is by using his headlights. So in the mystical life, reason has its function. The way of faith is necessarily obscure. We drive by night. Nevertheless our reason penetrates the darkness enough to show us a little of the road ahead. It is by the light of reason that we interpret the signposts and make out the landmarks along our way.
Those who misunderstand Saint John of the Cross imagine that the way of nada is like driving by night, without any headlights whatever. This is a dangerous misunderstanding of the saint's doctrine.

Context: Daddy grips the wheel and stares alone into the distance
He knows that something somewhere has to break
He sees the family home now, looming in his headlights
The pain upstairs that makes his eyeballs ache
Many miles away there's a shadow on the door
Of a cottage on the shore
Of a dark Scottish lake

This famous passage from her book is very often erroneously attributed to Nelson Mandela. About the mis-attribution Williamson said, "Several years ago, this paragraph from A Return to Love began popping up everywhere, attributed to Nelson Mandela's 1994 inaugural address. 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."

Variant which appears in the film Coach Carter (2005): "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. Your playing small does not serve the world. There is nothing enlightened about shrinking so that other people won't feel insecure around you. We are all meant to shine as children do. It's not just in some of us; it is in everyone. And as we let our own lights shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others."

Variant which appears in the film Akeelah and the Bee (2006), displayed in a picture frame on the wall, attributing it to Mandela: "Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. We ask ourselves, Who am I to be brilliant, gorgeous, talented, fabulous? Actually, who are you not to be? We were born to make manifest the glory of God that is within us. And as we let our own light shine, we unconsciously give other people permission to do the same."
