Rainn Wilson And Oprah: What Is Love? (VIDEO)

What is love, exactly? What does it look like? It all depends on who you're asking.

"Some say it's a chemical reaction," says Oprah in this "SoulPancake" sneak peek.

Whatever else love is, that four-letter word is one of the most fundamental human experiences. On Sunday, Dec. 16, in a special hourlong presentation on OWN, "SoulPancake" will view the topic of love through many lenses. You'll meet precocious kids, see some mindblowing art and hear three very different types of love stories:

  • A teacher whose hugs have given hope to many troubled youth.

  • A surgeon who literally holds human hearts in her hands. "Patients often worry, 'Will I be the same after she opens my chest? Will I be whole again? Will I be human again?'" she says.
  • And a couple whose love survived a devastating tragedy.
  • Tune in to "SoulPancake" on OWN on Dec. 16 at 12 p.m. ET.
