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.

Every Breath You Take (From the Archive)
We'll be back with a whole new season of How God Works on March 9th. But in the meantime, we wanted to share shows from our archives that speak to some of the most pressing challenges we're all facing today. It’s only February, and already this has been an intense year. So if you’re feeling stressed today, how about… a breather?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.

Finding Holiday Happiness
The holidays are supposed to be a time of joy.

Near Death Experiences
People have been having Near-Death Experiences (NDEs) all over the world for as long as we can look back into history. And the strange thing is… these experiences seem to have a lot in common. Why? Is it a look into the afterlife? Is it just our neurons firing in weird ways as the brain dies? We’ll talk to psychiatrist Bruce Greyson, one of the world’s leading experts on Near-Death Experiences, about the research that led him to rethink his understanding of the nature of life, death, and the continuity of consciousness. We’ll explore the science behind how these experiences can provide comfort, heal past trauma, and even create transcendent experiences that help us make as much sense of our lives as of impending death. And we’ll also consider the bigger question of what NDEs suggest, if anything, about our understanding of reality. Bruce Greyson, M.D. is the author of “After: A Doctor Explores What Near-Death Experiences Reveal About Life and Beyond.” Find out more about his book, and his over 45 years of experience researching NDEs, on his website. Here are links to the recordings of people you heard talking about their NDEs throughout the episode: Sharon Stone, Dr. Mary Neal, Renee Pasarow, Cherie Aimee, Jayne Smith.Here’s a video of Dr. Gregory Shushan talking about his research on NDEs in ancient religions.

So You say You’re a Cynic
There’s no question we’re living in difficult times that lead many of us to adopt a cynical outlook. But while cynicism might feel smart, science shows it’s corrosive not only to our own wellbeing, but to society as a whole. We’ll talk to Stanford Professor of Psychology Jamil Zaki about the surprising benefits that a willingness to trust in the goodness of others can offer, and how to build this skill in a wise way through habits of mind and action.We’ll also speak with political writer Peter Wehner about how cynicism leads to the political division and discord so prominent in politics today, and how religion, when practiced in its best form, can help overcome it.Jamil Zaki is the author of the new book Hope for Cynics: The Surprising Science of Human Goodness, and the author of The War for Kindness: Building Empathy in a Fractured Word.

Succeeding Without Trying
We spend a lot of time on How God Works talking about how spirituality can offer tools to become better versions of ourselves. And while learning to be happier, healthier and more resilient are all positive things to strive for, they can also lead us down a different path - an obsession with productivity and self-optimization… which can lead to a culture of trying to grind or life-hack our way through everything.But what if the secret to success lies in doing less, not more? On this episode, we’ll explore the Chinese concept of wu wei, effortless action. We'll talk to Edward Slingerland about how modern cognitive science has proven many early Chinese thinkers right, why wu wei is still relevant today, and how learning how not to try can help us forge a different path toward the good life.Edward Slingerland is a professor of religion at the University of British Columbia and the author of Trying Not To Try: Ancient China, Modern Science and the Power of Spontaneity. Find out more about his work, and his other books, on his website.Other texts we’ve discussed during this episode include: -Flow, by Mihaly Csikszentmihalyi-Groundwork of the Metaphysics of Morals, by Immanuel Kant-The Analects or Sayings of Confucius, attributed to Confucius-The Tao Te Ching or Laozi, attributed to Laozi-The Mencius, attributed to Mencius
