President Nelson Mandela's physical body has left this dimension, but his spiritual, political, economic, educational, and psychological impact he had on South Africa and the globe is a study in humanity. He was sent here to liberate a nation and a world, and inspire us that we can be greater than we were yesterday. Mandela was truly an angel, because his heart was pure, and he lived each day with a smile on his face.
