What Adele Diamond is learning about the brain challenges basic assumptions in modern education. Her work is scientifically illustrating the educational power of things like play, sports, music, memorization, and reflection. What nourishes the human spirit, the whole person, it turns out, also hones our minds.

He bestowed the title “Mahatma” on Gandhi. He debated the deepest nature of reality with Einstein. He was championed by Yeats and Pound to become the first non-European to win the Nobel Prize for Literature in 1913. Rabindranath Tagore was a polymath — a writer and a painter, a philosopher and a musician, and a social innovator — but much of his poetry and prose is virtually untranslatable (or inaccessibly translated) for modern minds. We pull back the “dusty veils” that have hidden his memory from history.

Yoga has infiltrated law schools and strip malls, churches and hospitals. This 5,000-year-old spiritual technology is converging with 21st-century medical science and with many religious and philosophical perspectives. Seane Corn takes us inside the practicalities and power of yoga. She describes how it helps her face the darkness in herself and the world, and how she’s come to see yoga as a form of body prayer.

For the Fourth of July, a refreshing reality check about the long road of American democracy. We remember forgotten but fascinating, useful history as we contemplate how we might help young democracies on their own tumultuous paths now.

Who knew that we learn empathy, trust, irony, and problem solving through play — something the dictionary defines as “pleasurable and apparently purposeless activity.” Dr. Stuart Brown suggests that the rough-and-tumble play of children actually prevents violent behavior, and that play can grow human talents and character across a lifetime. Play, as he studies it, is an indispensable part of being human.

As the daughter of Johnny Cash, singer-songwriter Rosanne Cash describes her life as “circumscribed by music.” But, it’s through her love of language and quantum mechanics that she’s finding new sources of creativity and mathematical ways to think about the divine. The mother of five shares her perspectives on being present, Twitter as a “boot camp for songwriters,” and how she wrestles with love and grief through her music.

Fairy tales don’t only belong to the domain of childhood. Their overt themes are threaded throughout hit TV series like Game of Thrones and True Blood, Grimm and Once Upon a Time. These stories survive, says Maria Tatar, by adapting across cultures and history. They are carriers of the plots we endlessly re-work in the narratives of our lives — helping us work through things like fear and hope.

The idea of reciting an unchanging creed sounds suspicious to modern ears. But the late, great historian Jaroslav Pelikan illuminated ancient tradition in order to enliven faith in the present and the future. He insisted that strong statements of belief will be necessary if pluralism in the 21st century is to thrive. We take in his moving, provocative perspective on our enduring need for creeds.

An astrophysicist who studies the shape of the universe, Janna Levin has also explored her science by writing a novel about two pivotal 20th-century mathematicians, Kurt Gödel and Alan Turing. Both men pushed at boundaries where mathematics presses on grand questions of meaning and purpose. Such questions, she says, help create the technologies that are now changing our sense of what it means to be human.

“Let’s go back and look at our faith before it was reduced to a system, before it was reduced to a system of abstractions and beliefs. How can we rediscover our faith as a series of stories and as a series of encounters?” Brian McLaren on the evolution of Christianity and the meaning of progressive Evangelicalism.

Dr. Sherwin Nuland died this week at the age of 83. He became well-known for his first book, How We Die, which won the National Book Award. For him, pondering death was a way of wondering at life — and the infinite variety of processes that maintain human life moment to moment. He reflects on the meaning of life by way of scrupulous and elegant detail about human physiology.

He is a genius of improvisation; a genre-bending vocal magician and conductor. And he sings the territory between music, mystery, and spirit. Who better to contemplate the human voice — its delights, its revelations, and its mystery — than Bobby McFerrin?

The writers Flannery O’Connor and Walker Percy, social activist Dorothy Day, and the Trappist monk Thomas Merton — all four shared a complex Catholic faith. Paul Elie takes us on a kind of literary pilgrimage through a Catholic imagination that still resonates in our time.

David Hartman died a year ago this week. The Orthodox rabbi was a charismatic and challenging figure in Israeli society, called a “public philosopher for the Jewish people” and a “champion of adaptive Judaism.” We remember his window into the unfolding of his tradition in the modern world — Judaism as a lens on the human condition.

The coming stage of evolution, Teilhard de Chardin said, won’t be driven by physical adaptation but by human consciousness, creativity, and spirit. We visit with his biographer Ursula King, and we experience his ideas energizing New York Times Dot Earth blogger Andrew Revkin and evolutionary biologist David Sloan Wilson.

The word “Vodou” evokes images of sorcery and sticking pins into dolls. In fact, it’s a living tradition wherever Haitians are found based on ancestral religions in Africa. We walk through this mysterious tradition — one with dramatic rituals of trances and dreaming and of belief in spirits, who speak through human beings, with both good and evil potential.

Talk show pioneer Phil Donahue opens up on his remarkable perspective on the last half century of America and who we are now. He shares his personal transformations on race, gender roles, and parenting in the dramatic era he captured on television.

What might words like repentance or forgiveness mean, culturally, in this moment? These are questions of the emerging church, a loosely-defined movement that crosses generations, theologies and social ideologies in the hope of reimagining Christianity. With Phyllis Tickle and Vincent Harding, an honest and sometimes politically incorrect conversation on coming to terms with racial identity in the church and in the world.
