Consider this quote from John Lewis in his book Across That Bridge: A Vision for Change and the Future of America,

“You are a light. You are the light. Never let anyone — any person or any force — dampen, dim or diminish your light… Release the need to hate, to harbor division, and the enticement of revenge. Release all bitterness. Hold only love, only peace in your heart, knowing that the battle of good to overcome evil is already won.”
