How God Works: The Science Behind Spirituality

For many people, the word “sin” is associated with harsh judgment and shame. Or, it’s used to talk about guilty pleasures like consuming decadent desserts... But is this concept as harmful or outdated as it seems?Join Dave as he talks with Elizabeth Oldfield about Christianity’s Seven Deadly Sins, and how reconceptualizing them for modern life can offer a science-backed user’s manual of sorts to find joy and connection in this world, whatever your beliefs.  Elizabeth Oldfield is host of The Sacred podcast and author of the book Fully Alive: Tending to the Soul in Turbulent Times. She also writes the Substack newsletter Fully Alive and works as a coach, consultant and facilitator. Find out more about her work on her website.

These days, it feels like the end of the world is always just around the corner. From RaptureTok to climate doom and geopolitical upheaval, someone always seems to be predicting an impending apocalypse. But how does believing in The End affect how we are in the world? And is there a healthier way to navigate living in uncertain times?On this episode, we’ll talk to writer Dina Nayeri about growing up in a community that saw the apocalypse as right around the corner, and what she now sees as the dangers of that worldview. We’ll also talk to historian Kim Haines-Eitzen about how the apocalypse was originally understood in ancient texts, and what’s been lost in modern interpretations.Dina Nayeri is the author of the essay “Yearning for the end of the world,” as well as several other novels, plays, short stories, essays, and memoirs, including her most recent book, Who Gets Believed: When the Truth Isn’t Enough.

 We spend about a third of our lives sleeping and yet the question of why we sleep and dream has remained a mystery for much of human existence. But recently scientists have developed the tools to begin to reveal some astonishing insights into lucid dreaming and its uses.  In this episode, we'll talk to neuroscientist Ken Paller about the science of Lucid dreaming. Whether it's something any of us can learn to do and what benefits it might offer. And while the science of lucid dreaming and its possible uses is still in its infancy, Tibetan Buddhists found ways to master it centuries ago using a practice they call Dream Yoga.  We'll talk with Geshe Thabkhe, a Tibetan Buddhist monk, about how members of his tradition have long been using this technique to enhance their spiritual lives, and how he and other monks are now working with Western scientists like Ken Paller and neuroscientist Robin Nusslock to research this special type of dream state and whether people in the outside world can influence or even communicate with them while they're dreaming. Robin Nusslock, PhD is a neuroscientist and Associate Professor of Psychology at Northwestern University. Ken Paller is Professor of Psychology and Director of  the Cognitive Neuroscience program at Northwestern University.

When life feels uncertain, who do you turn to? Across cultures and throughout history, many of us have looked to people who seemed to have a special set of abilities and knowledge… shamans.On this episode, we’ll talk to anthropologist Manvir Singh about what shamanism actually is, how it works, and why its appeal is both timeless and universal. From a remote island in Indonesia to American Pentecostal churches, we’ll explore how shamans harness ritual, empathy, and performance to help people find meaning and relief in times of need.Manvir Singh directs the Integrative Anthropology Lab at the University of California, Davis. He is the author of Shamanism: The Timeless Religion, and a contributing writer for The New Yorker. Find out more about his work on his website.

For most of human history, religion guided people’s choices about health and food. Then with the rise of modern nutritional science in the 19th century, people began to favor scientific advice over religious ideas about how to eat. But lately, a new generation of Christian diet influencers are putting the God back in nutritional guidance, sometimes at the expense of science altogether. And this messaging might not be creating healthier or holier people. We'll talk to New York Times writer Jessica Grose and historian Catherine Newell about the long, complex history of food, faith, and morality.  And we’ll ask - can we reconnect faith and health in America in positive ways that are informed by tradition and history, but also true to science?Jessica Grose has written books on motherhood, marriage and countless articles.

She is the author of the books entitled Food Faiths: Diet, Religion, and the Science of Spiritual Eating & Destined for the Stars: Faith, the Future, and America’s Final Frontier.
