How God Works: The Science Behind Spirituality
While religion and science often seem at odds, there’s one thing they can agree on: people who take part in spiritual practices tend to live longer, healthier, and happier lives. The big question is: Why? In How God Works, professor Dave DeSteno takes us on a journey to find out how spirituality impacts our minds and bodies, as well as the world in which we live.He speaks to leading scientists and philosophers, religious thinkers, and thought leaders to explore what we can learn from the world’s faith traditions to help us meet some of life’s biggest challenges. Along the way, he’ll look at how we can adapt and use spiritual practices in our own lives, whatever our beliefs, including none at all.It’s by working across the boundaries that usually divide us – science versus religion, one faith versus another – that we’ll find new ways to make life better for everyone.

U.F.Whoa!
Religion is often about powerful beings coming down from the skies and humans yearning to go up to join them. Does that mean we can swap aliens in for God? More and more people seem to think so. In fact, many spiritually-minded people are looking to UFOs as opportunities to commune with enlightened alien teachers. Some believe they’re even aliens themselves, sent here to prepare us for a new age. But when religion gets mixed with conspiracy theory, things can sometimes take a darker turn.
Join Dave as he speaks with religious studies professor Diana Walsh Pasulka, about what belief in UFOs might share with other religions, and with anthropologist Susannah Crockford about how and why conspiracy theories are giving rise to a new spiritual movement.
Diana Walsh Pasulka is the author of Encounters: Experiences with Nonhuman Intelligence and American Cosmic: UFOs, Religion, Technology. Find out more about her work on her website.
Susannah Crockford is the author of Ripples of the Universe: Spirituality in Sedona, Arizona, and the host of the new podcast Miss Information, a podcast about the ways online misinformation and conspiracy theories infiltrate wellness communities and conservative Christian spaces.

The Power of Pilgrimage
What makes a trip a pilgrimage? And why have people from across the globe made these treks for millennia? Is it the destination that makes these journeys so important to so many cultures? Or is it the community and meaning-making that happen along the way? And how are people changed by the experience after they come home?
Join Dave as he talks with writer and New York Times contributor Aatish Taseer about what he saw last year when he went on pilgrimages into the hearts of three faiths. And with psychologist and leading pilgrimage scholar Heather Warfield, about how these treks, even in secular form, can improve mental health and wellbeing.
Aatish Taseer is the author of A Pilgrimage Year. Special thanks to Aatish for sharing recordings from his travels with us for use in today’s episode. Follow him on X @aatishtaseer and Instagram @aatishalitaseer.

Is War Holy?
Is religion a source of conflict, or a way to end it? From the tragic situation in the Middle East to rising Christian Nationalism in the US, it might seem the former. But for faiths that emphasize love, compassion, and forgiveness, might the latter also be true?
Join Dave as he talks with theologian Miroslav Volf about how religion blurs with political identity and violent ideologies, and why the answer to this problem might not be to remove religion from our lives and the public square, but to have more of it in both. And with anthropologist Benjamin Purzycki about how our views of what God wants can change in the face of conflict.
Miroslav Volf is a Professor of Theology at Yale Divinity School and the Director of the Yale Center for Faith & Culture. Learn more about his work here and check out his podcast For the Life of the World.

Finding Hope in Dark Times
Surveys show feelings of sadness and despair peaked in 2023. So as we look to the new year, it's understandable why any of us might be feeling pessimistic, even hopeless. But these feelings aren't written in stone. We always have a choice. It's in these darkest of times, when all feels lost, that hope helps us find our way...not just to heal ourselves, but also the world around us.
On this episode, we'll talk with the Pulitzer Prize winning New York Times columnist Nicholas Kristof, about how he remains motivated and hopeful, even while covering some of the most tragic events in recent history. And he’ll offer a little advice for ways we can all rise above despair.
And we'll talk with Roshi Joan Halifax -- ecologist, civil rights activist, hospice caregiver, and founder of the Upaya Zen Center -- about the Buddhist-informed notion of wise hope, the equanimity it can bring, and the fierce compassion it can unleash.
Nicholas Kristof is the author of the forthcoming book Chasing Hope. Read his NYT columns here, and find out more about the cider he makes here.
Roshi Joan Halifax leads the Upaya Zen Center in Santa Fe, New Mexico. Learn more about her work on her website.

Religion & Mental Health Part 2: Addiction
When it comes to treating addiction, twelve-step programs like Alcoholics Anonymous are some of the most often used in the US. But while twelve-step programs have several components, one of the most central is surrendering control to a higher power. But how important is that idea? Does relying on a divine influence help or hurt? And might there be other routes to recovery?
We’ll talk with bestselling author and New York Times opinion writer Maia Szalavitz about what the research on addiction and addiction recovery shows, as well as her own path out of drug abuse. And we’ll discuss the relationship between perceptions of “divine control” and personal wellbeing with sociologist Laura Upenieks.
Maia Szalavitz is the author of Undoing Drugs: How Harm Reduction is Changing the Future of Drugs and Addiction. Learn more about the book, and her other writings, on her website.
Laura Upenieks is an Assistant Professor of Sociology at Baylor University. Learn more about her research here.
If you or someone you know is struggling with addiction there are many resources out there to help. Among the options Maia recommends exploring to see if they are right for you: SMART Recovery, Women for Sobriety, and Alcoholics Anonymous.

Religion & Mental Health Part 1: Psychotherapy
For most of the past 200 years, religion and psychiatry didn’t get along too well. Or so the story goes. But if you go back far enough, the two have more in common than you might think.

We’ll talk with psychiatrist Rania Awaad about her work reconnecting the Muslim community to Islam’s long, but often forgotten, history of mental health treatment. And with psychologist David Rosmarin about the program he’s pioneered at McLean hospital to integrate spirituality into psychiatric treatment.

Every Breath You Take
It’s no accident that the Hebrew word for breath is the same as the word for spirit (ruach). Breath doesn’t just give us life: it helps regulate everything from vital organ functions to cognition and emotional states. That’s why spiritual traditions the world over incorporate it as a practice to help heal body and mind and walk the path towards peace.
Join us as we explore the breath’s connection to our nervous system with psychologist and neuroscientist Stephen Porges, creator of Polyvagal Theory. We’ll also learn about the spiritual roots of breathwork and try out a few techniques with noted yoga, qigong and meditation teacher Amelia Barili.
Learn more about Dr. Stephen Porges’s work and Polyvagal Theory on his website, and be sure to check out his new book, co-authored with Seth Porges: Our Polyvagal World: How Safety and Trauma Change Us.
Dr. Amelia Barili is faculty at the UCB Osher Lifelong Learning Institute and professor emerita from the University of California at Berkeley. Learn more about her work on her website and check out her YouTube channel the new paradigms.
We also highly recommend the book Breath: The New Science of a Lost Art, by James Nestor.

Touching the Transcendent
We’ve all heard of spiritual experiences – moments of feeling intense awe and deep love and connection. People who’ve had them – and it’s a lot more than you might think – see them as some of the most profound moments of their lives. Moments that change them for the better in enduring ways. But what’s going on in our brains when these experiences happen? Do you even need religious beliefs to have them? And, if you’re so inclined, how might you start?
