Back when my son was 8 years old, he called 911 after I took away his Game Boy. I wish I’d been studying Buddhism back then, because I probably could have handled it a lot better. I suspect I wouldn’t have yelled at him while the dispatcher was still listening. And I bet I wouldn’t have been quite so wracked by dread when the police were questioning us in separate rooms of the house—at least until I overheard the other officer ask, “She took away your what?”

Most importantly, I know I would have forgiven my son much more quickly, and the whole thing wouldn’t have felt so traumatic. I might even have gazed upon him with compassion.

Looking back, I realize I was completely underutilizing my own brain. It is small comfort that so many otherwise sane mortals share this failing. Our attention flickers, our patience ebbs and—propelled by fear, malice, craving and other deeply inscribed passions—we lurch from impulse to action.

In contrast, practiced Buddhist meditators deploy their brains with exceptional skill. Drawing on 2,500 years of mental technology—techniques for paying careful attention to the workings of their own minds—they develop expertise in controlling the flow of their mental life, avoiding the emotional squalls that often compel us to take personal feelings oh, so personally, and clearing new channels for awareness, calm, compassion and joy. Their example holds the possibility that we can all choose to modulate our moods, regulate our emotions and increase cognitive capacity—that we can all become high-performance users of our own brains.

“What we’re talking about is a long-term strategy for cultivating the heart and mind to fully draw forth the beneficial capacities of the human mind,” says B. Alan Wallace, founder and president of the Santa Barbara Institute for Consciousness Studies. A Buddhist scholar who examines the interface between science and religion, he believes that much of human suffering is our own doing. Our feelings contract around threats to our sense of self and cloud our sense perceptions. We end up reacting, as if we had no other choice.

Meditation alters what we tend to think of as stable mental traits—anxiety, for example, or anger. Practitioners discover that feelings are events that rise in the psyche like bubbles off the bottom of a pot of boiling water. “They learn to de-identify with their emotions, making it easier to let them go,” says neuroscientist Richard Davidson of the University of Wisconsin at Madison.

As the result of an extraordinary convergence of scientific research into interior states and new understanding of an ancient spiritual tradition, says Jon Kabat-Zinn, founder of the pioneering Stress Reduction Clinic at the University of Massachusetts Medical Center, “Buddhist meditation is leading to an expansion of the science of what it means to be human.”

Ten Million Americans Can’t All Be Wrong

Some 10 million Americans say they practice some form of meditation. Buddhism is unique among spiritual traditions in its emphasis on psychology. Its core teachings encourage practitioners to shake off suffering and discover happiness. The very concept of self-improvement informs bhavana, the Sanskrit word commonly translated as “meditation,” though it literally means “cultivation.” “It has exactly the same connotation as when we say we ‘cultivate a garden,’ ” says Wallace.

It remains a radical notion in the West that benevolent states of mind such as concentration, kindness and happiness can be developed with practice. Apart from a growing “positive psychology” movement, many of whose leaders are in fact strongly influenced by Buddhism, Western scientists are still largely oriented toward healing the mentally ill, rather than improving the lives of the functionally OK. Recollect Freud’s humble goal: to transform hysterical misery into common unhappiness. Western science is content to believe that each of us has a more or less genetically determined set point for well-being—and that happiness and love happen to us.

The Buddha framed things differently. He taught that our default mode may be to suffer, but only because of ignorance. We can transcend our lot by learning to quiet the mind in meditation—not merely to relax and cope with stress, as the popular notion of Buddhism holds, but to rigorously train oneself to relinquish bad mental habits. Rather than being an end in itself, meditation becomes a tool to investigate your mind and change your worldview. You’re not tuning out so much as tuning up your brain, improving your self-monitoring skills.

“You stop being always projected outside. You start looking in and seeing how your mind works, and you change your mind, thought by thought,” explains Matthieu Ricard, a Buddhist monk, scientist and French interpreter for the Dalai Lama. “The French intellectuals don’t like this. They say, ‘Let’s be spontaneous; passions are the beauty of life.’ They think that making an effort is not nice—a silly old discipline—and that’s why we’re such a mess. But many modern people understand the notion of getting fit with physical training.” So the idea of developing mental skills with meditation is gaining ground.

The Nod From Neuroscience

Encouragement for this new way of thinking comes from an unusual ally. Neuroscience is furnishing hard evidence that the brain is plastic, endowed with a lifelong capacity to reorganize itself with each new experience. “We now know that neural firing can lead to changes in neural connections, and experience leads to changes in neural firing,” explains UCLA psychiatrist Daniel Siegel. Violinists’ brains actually change as they refine their skill. So do the brains of London cabbies, whose livelihood depends on the sharpness of their memory. Likewise, through repeated practice in focusing attention, meditators may be strengthening the neural circuitry involved in the voluntary control of attention.

One Tibetan lama told Wallace that before training, his mind was like a stag with great antlers trying to make its way through a thick forest; the animal got snagged on branches time after time. But after many years of practice, his mind was more like a monkey in a jungle, swinging freely from vine to vine.

Such adepts are the Lance Armstrongs of meditation, says Davidson, whose pioneering brain scans of monks provide tantalizing evidence that emotions like love and compassion are in fact skills—and can be trained to a dramatic degree. Studies also suggest that the monastic life is not a requirement; even brief, regular meditation sessions can yield substantial benefits. Nor is a belief in Buddhism necessary. “I’m convinced that you can make a huge difference in your life if you start out with even 30 minutes a day,” Ricard says. “By maintaining the practice, there is a trickle of insights. Drop by drop, you fill a jar.”

One recent study at Massachusetts General Hospital found that 40 minutes of daily meditation appears to thicken parts of the cerebral cortex involved in attention and sensory processing. In a pilot study at the University of California at San Francisco, researchers found that schoolteachers briefly trained in Buddhist techniques who meditated less than 30 minutes a day improved their moods as much as if they had taken antidepressants.

There are many types of meditation, and they can be used to develop a number of mental skills. This attitude focuses on practices that address common emotional struggles. Through basic meditation techniques, it’s possible to cultivate a longer attention span, develop emotional stability, understand the feelings of others and release yourself from the constraints you place on your own happiness.

Attention: Stabilize the Mind

Computers, pagers, video games, telemarketing calls, nonstop e-mail—all blast our attention span to smithereens. Modern life does a swell job of distracting us. But perhaps the problem lies not in our cell phones but in ourselves. After all, we’re the ones constantly making choices about what to attend to and what to ignore.

The trouble is, most of us make these choices semiconsciously at best. We don’t even attempt to control our attention, perhaps because we don’t know how. Buddhists maintain that the capacity can be refined through a consistent practice of meditation: The mind is by nature unstable, inherently distractible, and meditation is a means of stabilizing it.

“Meditation is about paying attention,” says Kabat-Zinn. Cultivating concentration doesn’t just stabilize and clarify the mind, it can also improve creativity and productivity while enhancing relationships. Imagine if you actually paid attention 100 percent to your spouse!

The strategy that starts you on this road is mindfulness, which means both cultivating nonjudgmental awareness of a specific object and seeing deeply into things. A common approach is to focus on an object or on the sensations of your own breathing, noting every inhale and exhale, and patiently returning your attention to your breathing each time it wanders.

“You practice focusing on one object,” says Clifford Saron, a neuroscientist at the Center for Mind and Brain at the University of California at Davis. “You begin to observe the flux of moment-to-moment perception. With practice you can detect patterns in those fluctuations.”

It’s like you’re flexing a muscle in the brain. University of Wisconsin’s Davidson contends that the mental exercise of meditation strengthens and stabilizes neural networks in the medial prefrontal cortex—the brain’s executive control center, involved in the regulation of attention. “People don’t recognize that there is lots of plasticity in the circuitry,” he adds. “More than previously thought.”

The effort in the exercise is to balance awareness between dullness and distraction. To do so, you use the self-monitoring process that psychologists call metacognition: awareness of awareness. It’s what lets you know when, on the one side, you’re starting to drift off and need to muster fresh interest and, on the other, you’re getting distracted and need to bring your attention back. As you gradually fine-tune your concentration, you notice the habitual chaos of your thoughts and, gradually, the calm that lies behind them. “Awareness trumps thoughts,” says Kabat-Zinn, “because you can be aware of your thoughts.”

In his book, The Attention Revolution: Unlocking the Power of the Focused Mind, Wallace describes a nine-stage program to achieve quiescence, a state the Buddhists call shamatha (pronounced sha-ma-ta). As one Buddhist scholar put it, attention becomes “an oil lamp unmoved by the air; wherever the awareness is directed, it is steady and sharply pointed.”

Even among novices, studies show, a brief meditation session can be more effective than a nap in improving performance on tests that require concentration. But its benefits don’t stop there. Meditation can radically transform emotion.
