Oprah says sitting down with Nobel Prize winner and human rights activist Elie Wiesel was a "privilege of a lifetime." This Sunday, Elie opens up to Oprah about his emergency heart surgery. "We get an opportunity to talk about those moments of him being on the operating table and his thoughts about who he was and all the things he had left to do, which was really surprising to know that at 82 years old he still felt like he had so much undone," Oprah says.

Watch as Oprah reflects on the moments from the interview that most resonated with her. Then, tune in Sunday at 11 a.m. ET/PT to watch their complete conversation on OWN or online.

 

Neurosurgeon Dr. Eben Alexander was strictly a man of science, a skeptic of the existence of a soul or God, until a near-death experience changed his entire perspective on life and faith. In his best-selling book, Proof of Heaven, Dr. Alexander opens up about the rare form of meningitis that shut down part of his brain—and how he says he experienced heaven against all medical odds.

Now, Dr. Alexander is talking to Oprah. Their conversation, which Oprah says lasted for two hours, will air in a one-hour "Super Soul Sunday" on January 20. "I just talked to a man who saw God," Oprah says. "He talks about how that experience of heaven has now changed the way he lives here on earth and how it can change the way we all live."

Oprah says Dr. Alexander agrees with a belief she's always had: that newborns and young children are still attuned to a spiritual realm. Watch the video above for Oprah's thoughts and to see part of that discussion.

Jean Houston is a thought leader, an anthropologist, a wisdom teacher—and the interviewee that caused Oprah to do something she's never done after an interview. "When I finished the interview, I asked for a transcript so I could actually process what had been said because the information and the aha's were coming so fast I couldn't even process it," Oprah says. "This is the first time this has ever happened to me."

Watch Oprah share why Jean is someone you have to experience for herself, and get a sneak peek of their conversation about the great potential everyone has the ability to achieve.

Oprah says Gabrielle Bernstein, Mastin Kipp and Marie Forleo represent the new breed of spiritual thought leaders. "I was so happy to have them all together here for a 'Super Soul Sunday' event," Oprah says. "What they have to say [is] going to inspire you."

Watch the video above for more of Oprah's thoughts on this week's show and find out why Gabrielle, Mastin and Marie believe their generation is so spiritually aware and what lessons they are teaching the world. Plus, find out if these real-life friends ever feel competitive with one another.
