There may be no other actor on the world’s stage whose life has been as heavily documented as Muhammad Ali's. Yet for all the ways the legendary athlete and humanitarian’s life has been scrutinized and celebrated, few have attempted to tell the story of what he valued most: his spiritual evolution. From America Abroad Media, The Muhammad Ali Center, and PRX, “The Universal Title” is a six-episode special on Muhammad Ali’s spiritual journey from Christianity to Islam — And what really made him ‘The Greatest.’ Hosted by Preacher Moss.
