Bardo has a poetic beginning and upbeat ending, with roots in several diverse cultures. It may be most familiar today via George Saunders' novel Lincoln in the Bardo, which refers to the Tibetan Buddhist state of suspension between one life and the next, resembling the Christian idea of Limbo. Bardo is also an ancient saint's name: Saint Bardo was the eleventh century bishop of Mainz, in Germany. Actress Sandra Bullock chose Bardo as her son's middle.
