(CNN) - Sooner or later, it happens to each of us, Richard Rohr says.

“There always will be at least one situation in our lives that we cannot fix, control, explain, change or even understand,” the Franciscan priest said.

Maybe you’ve been laid off from a job you held for years. Perhaps you’ve experienced a nasty divorce. Or maybe the crisis is more subtle: You suddenly realized that you’ll never have the life you dreamed of living.

Any life-changing moment can knock a person down. But it can also open doors if, as Rohr puts it, a person learns how to “fall upward.”

Rohr, a 68-year-old Roman Catholic author and internationally known speaker, says older Americans face a problem: Religious leaders aren’t paying much attention to them.

Much of contemporary religion is geared toward teaching people how to navigate the first half of their lives, when they’re building careers and families. Rohr calls it a “goal-oriented” spirituality.

Yet there’s less help for people dealing with the challenges of aging: the loss of health, the death of friends, and coming to terms with mistakes that cannot be undone, he says.

Rohr’s new book, “Falling Upward: A Spirituality for the Two Halves of Life,” is his attempt to fill that void. It also functions as a spiritual survival guide for hard times as millions of Americans young and old struggle to cope with “falling”: losing their homes, careers and status.

Rohr says he coined the phrase “falling upward” to describe a paradox. Nearly everyone will fall in life because they'll confront some type of loss, he says. Yet failure can lead to growth if a person makes the right decisions.

“I’ve met people who because of the loss of things and security have been able to find grace, freedom and new horizons,” he said.

If you’re falling in any area of your life, Rohr says, one of the first skills to learn is accepting surprises.

He says it’s easy for people to turn bitter when things don’t go as planned. He sees such people all the time, whether throwing tantrums at the airport because of long lines or flocking to angry rallies in opposition to some form of social change.

“You start attacking anybody else who is not like you,” Rohr said. “If you don’t know how to deal with exceptions, surprise and spontaneity by the time you’re my age, you become a predictable series of responses of paranoia, blame and defensiveness.”

Why suffering is necessary

Rohr’s book may address contemporary issues, but the wisdom is old. He extracts insights from sources as varied as Greek mythology, Catholic mysticism and fairy tales like Cinderella.

Such stories often teach similar lessons about hard times: Suffering is necessary, the “false self” must be abandoned, and “everything belongs, even the sad, absurd and futile parts.” Rohr, who has also written “Quest for the Grail,” a book on mythology, says people have learned these hard lessons for centuries through myth.

The heroes in mythological stories follow the same pattern. They must first experience humiliation, loss and suffering before finding enlightenment. They are often forced on their journey by a crisis.

No contemporary American is going to be asked to fight a monster, but an event like the evaporation of a retirement fund or the death of a spouse can force you to summon strength you didn’t know you had, Rohr says.

The key is not resisting the crisis.

“You have to allow the circumstances of God and life to break you out of your egocentric responses to everything,” he said. “If you allow ‘the other’ - other people, other events, other religions - to influence you, you just keep growing.”

That growth, though, is accompanied by death - the death of the “false self,” Rohr said. The false self is the part of your self tied to your achievements and possessions.

When your false self dies, you start learning how to base your happiness on more eternal sources, he says.

“You start drawing from your life within,” Rohr said. “You learn to distinguish from the essential self and the self that’s window dressing.”

Those who break through the crisis and lose their false selves become different people: less judgmental, more generous and better able to ignore “evil or stupid things,” he says.

It may sound esoteric, Rohr says, but many of us have met older people like this. They possess a “bright sadness”: they’ve suffered but they still smile and give.

“I’ve seen that in the wonderful older people in my life,” Rohr says. “There’s a kind of gravitas they have. … There’s an easy smile on their faces. These are the people who laugh, who heal, who build bridges, who don’t turn bitter.”

Rohr says this bright sadness isn’t confined to older people.

“I've met 11-year-old children in cancer wards who are in the second half of life,” he said in a recent interview with Amazon.com, “and I have met 68-year-old men like me who are still in the first half of life.”

Learning the ‘grace of failure’

Rohr’s book has found some fans in high places who were touched by his insights.

Father Gerry Blaszczak, a chaplain at Fairfield University in Connecticut, says Rohr’s book challenges the notion that success is a natural result of being religious.

“Our culture is prone to imagine that growth takes place in a sort of constant, upward movement,” he says. “Even our religious culture tends to focus on success and stability as ideals for religious growth.”

Rohr’s book reminds people about the “grace of failure,” Blaszczak says.

“In the Christian tradition, loss, collapse and failure have always been seen as not only unavoidable, but even necessary on the path to wisdom, freedom and personal maturity,” Blaszczak said.

He says he knows older people who struggled to rebuild their identities after they poured much of their earlier lives’ energies into professional and personal success.

“It is not that these professional or personal ideas were necessarily bad in themselves,” he said. “It is more that they proved inadequate. We invested way too much in them. We thought our identities could be formed by them.”

Jim Finley, a retreat leader and Catholic scholar, says Rohr is reminding people about the value of elders.

“Our culture tends to be youth-oriented, and a lot of spirituality is youth oriented,” says Finley, author “The Contemplative Heart.” “But our elders are the embodiment of the wisdom that life matters at a much deeper level than what we can achieve and produce.”

Brian McLaren, author of “The Naked Spirituality,” says Rohr’s book touches on an important paradox that you probably won’t hear in a Sunday morning sermon: “Imperfect people” are sometimes more equipped than “perfect people” to help those who are struggling.

“The person who never makes a mistake and always manages to obey the rules is often a compassionless person, because he sees people for whom the wheels have fallen off and he wonders what’s wrong with them,” he said. “But the person who feels that he has ruined his life often has more capacity for humility and compassion.”

McLaren says Rohr’s book helped reveal to him how much of his youthful spiritual energy was driven by narrow concerns.

“I’m embarrassed as I’m getting older about how much of my energy and vitality as a younger man was driven by ego and a win-lose mentality.”

Today Rohr seems driven by something else: The need for rest.

For years, his life has been a whirlwind. He’s traveled the globe speaking at retreats on everything from men’s spirituality to Catholic mysticism.

He also founded the Center for Action and Contemplation in Albuquerque, New Mexico, an organization that encourages acts of justice rooted in prayer and respect for other religious traditions.

Yet after almost seven decades of living, Rohr said, “I am still a mystery to myself.”

Rohr plans on solving some of that mystery. He says he’s going to retire in two years to spend more time at his home in New Mexico. He says he needs more time for contemplation.

“The first half of life, you write the text,” he said. “The second half of your life is when you write the commentary. You have to process what it all meant.”

As Rohr withdraws from speaking and writing, he will be challenged to follow his own advice. He’ll spend less energy on his “false self” as his old identity dissolves.

He says he’s ready, though, to fall upward. If he lost his position as a priest, author and respected speaker, he says he would still feel secure.

“Most of us don’t learn this until it is taken away, like losing the security of your 401(k). Then the learning either starts or you circle the wagons,” he said. “I know who I am beyond my roles.”
