Nobel Peace Prize winner Elie Wiesel is one of Oprah's personal heroes. In 2006, Oprah traveled to Auschwitz death camp in Poland to learn firsthand from Elie—a Holocaust survivor—about the horror he recounted in his book, Night.

This Sunday, Oprah is sitting down once more with the man "who's lived through hell without ever hating." At 11 a.m. ET/PT, Oprah is sitting down for an all-new conversation with Elie Wiesel about life after emergency open heart surgery. 

At 12 p.m. ET/PT, stay tuned for an encore presentation of their trip to Auschwitz. It's a show you'll want to watch again and share with others.

Before then, watch as Oprah opens up about lessons we can all learn from that sobering visit.

Plus, Oprah shares why visiting Auschwitz with Elie was a "life-fulfilling moment."
