(CNN) - At Nelson Mandela's memorial service Tuesday, President Barack Obama said the icon's death should prompt a time for self-reflection.
"With honesty, regardless of our station or our circumstance, we must ask: how well have I applied his lessons in my own life?" Obama said. "It is a question I ask myself - as a man and as a president. We know that like South Africa, the United States had to overcome centuries of racial subjugation. As was true here, it took sacrifice - the sacrifices of countless people - known and unknown - to see the dawn of a new day."
