Meditation Gives Brain a Charge, Study Finds
Meditation Gives Brain a Charge, Study Finds
By Marc Kaufman
Washington Post Staff WriterMonday, January 3, 2005; Page A05
Brain research is beginning to produce concrete evidence for something that Buddhist practitioners of meditation have maintained for centuries: Mental discipline and meditative practice can change the workings of the brain and allow people to achieve different levels of awareness.
Those transformed states have traditionally been understood in transcendent terms, as something outside the world of physical measurement and objective evaluation. But over the past few years, researchers at the University of Wisconsin working with Tibetan monks have been able to translate those mental experiences into the scientific language of high-frequency gamma waves and brain synchrony, or coordination. And they have pinpointed the left prefrontal cortex, an area just behind the left forehead, as the place where brain activity associated with meditation is especially intense.
"What we found is that the longtime practitioners showed brain activation on a scale we have never seen before," said Richard Davidson, a neuroscientist at the university's new $10 million W.M. Keck Laboratory for Functional Brain Imaging and Behavior. "Their mental practice is having an effect on the brain in the same way golf or tennis practice will enhance performance." It demonstrates, he said, that the brain is capable of being trained and physically modified in ways few people can imagine.
Scientists used to believe the opposite -- that connections among brain nerve cells were fixed early in life and did not change in adulthood. But that assumption was disproved over the past decade with the help of advances in brain imaging and other techniques, and in its place, scientists have embraced the concept of ongoing brain development and "neuroplasticity."
Davidson says his newest results from the meditation study, published in the Proceedings of the National Academy of Sciences in November, take the concept of neuroplasticity a step further by showing that mental training through meditation (and presumably other disciplines) can itself change the inner workings and circuitry of the brain.
The new findings are the result of a long, if unlikely, collaboration between Davidson and Tibet's Dalai Lama, the world's best-known practitioner of Buddhism. The Dalai Lama first invited Davidson to his home in Dharamsala, India, in 1992 after learning about Davidson's innovative research into the neuroscience of emotions. The Tibetans have a centuries-old tradition of intensive meditation and, from the start, the Dalai Lama was interested in having Davidson scientifically explore the workings of his monks' meditating minds. Three years ago, the Dalai Lama spent two days visiting Davidson's lab.
The Dalai Lama ultimately dispatched eight of his most accomplished practitioners to Davidson's lab to have them hooked up for electroencephalograph (EEG) testing and brain scanning. The Buddhist practitioners in the experiment had undergone training in the Tibetan Nyingmapa and Kagyupa traditions of meditation for an estimated 10,000 to 50,000 hours, over time periods of 15 to 40 years. As a control, 10 student volunteers with no previous meditation experience were also tested after one week of training.
The monks and volunteers were fitted with a net of 256 electrical sensors and asked to meditate for short periods. Thinking and other mental activity are known to produce slight, but detectable, bursts of electrical activity as large groupings of neurons send messages to each other, and that's what the sensors picked up. Davidson was especially interested in measuring gamma waves, some of the highest-frequency and most important electrical brain impulses.
Both groups were asked to meditate, specifically on unconditional compassion. Buddhist teaching describes that state, which is at the heart of the Dalai Lama's teaching, as the "unrestricted readiness and availability to help living beings." The researchers chose that focus because it does not require concentrating on particular objects, memories or images, and cultivates instead a transformed state of being.
Davidson said that the results unambiguously showed that meditation activated the trained minds of the monks in significantly different ways from those of the volunteers. Most important, the electrodes picked up much greater activation of fast-moving and unusually powerful gamma waves in the monks, and found that the movement of the waves through the brain was far better organized and coordinated than in the students. The meditation novices showed only a slight increase in gamma wave activity while meditating, but some of the monks produced gamma wave activity more powerful than any previously reported in a healthy person, Davidson said.
The monks who had spent the most years meditating had the highest levels of gamma waves, he added. This "dose response" -- where higher levels of a drug or activity have greater effect than lower levels -- is what researchers look for to assess cause and effect.
In previous studies, mental activities such as focus, memory, learning and consciousness were associated with the kind of enhanced neural coordination found in the monks. The intense gamma waves found in the monks have also been associated with knitting together disparate brain circuits, and so are connected to higher mental activity and heightened awareness, as well.
Davidson's research is consistent with his earlier work that pinpointed the left prefrontal cortex as a brain region associated with happiness and positive thoughts and emotions. Using functional magnetic resonance imagining (fMRI) on the meditating monks, Davidson found that their brain activity -- as measured by the EEG -- was especially high in this area.
Davidson concludes from the research that meditation not only changes the workings of the brain in the short term, but also quite possibly produces permanent changes. That finding, he said, is based on the fact that the monks had considerably more gamma wave activity than the control group even before they started meditating. A researcher at the University of Massachusetts, Jon Kabat-Zinn, came to a similar conclusion several years ago.
Researchers at Harvard and Princeton universities are now testing some of the same monks on different aspects of their meditation practice: their ability to visualize images and control their thinking. Davidson is also planning further research.

"What we found is that the trained mind, or brain, is physically different from the untrained one," he said. In time, "we'll be able to better understand the potential importance of this kind of mental training and increase the likelihood that it will be taken seriously."

A Guide to Cultivating Compassion in Your Life
A Guide to Cultivating Compassion in Your Life
by His Holiness the Dalai Lama
Tenzin Gyatso, the XIV Dalai Lama, is the leader of Tibetan Buddhism, the head of the Tibetan government-in-exile, and a spiritual leader revered worldwide. He was born on July 6, 1935 in a small village called Taktser in northeastern Tibet. Born to a peasant family, he was recognized at the age of two, in accordance with Tibetan tradition, as the reincarnation of his predecessor, the XIIIth Dalai Lama. The Dalai Lamas are manifestations of the Buddha of Compassion, who choose to reincarnate for the purpose of serving human beings. Winner of the Nobel Prize for Peace in 1989, he is universally respected as a spokesman for the compassionate and peaceful resolution of human conflict. He has traveled extensively, speaking on subjects including universal responsibility, love, compassion and kindness.
I believe compassion to be one of the few things we can practice that will bring immediate and long-term happiness to our lives. I’m not talking about the short-term gratification of pleasures like sex, drugs or gambling but something that will bring true and lasting happiness. The kind that sticks.
The key to developing compassion in your life is to make it a daily practice.
Meditate upon it in the morning (you can do it while checking email), think about it when you interact with others, and reflect on it at night. In this way, it becomes a part of your life. There is no need for temples; no need for complicated philosophy. Our own brain, our own heart is our temple; the philosophy is kindness.
What is Compassion?
Compassion is an emotion that is a sense of shared suffering, most often combined with a desire to alleviate or reduce the suffering of another; to show special kindness to those who suffer. Compassion essentially arises through empathy, and is often characterized through actions, wherein a person acting with compassion will seek to aid those they feel compassionate for.
Compassionate acts are generally considered those which take into account the suffering of others and attempt to alleviate that suffering as if it were one’s own. In this sense, the various forms of the Golden Rule are clearly based on the concept of compassion.Compassion differs from other forms of helpful or humane behavior in that its focus is primarily on the alleviation of suffering.
Benefits
Why develop compassion in your life? Well, there are scientific studies that suggest there are physical benefits to practicing compassion — people who practice it produce 100 percent more DHEA, which is a hormone that counteracts the aging process, and 23 percent less cortisol — the “stress hormone.”
But there are other benefits as well, and these are emotional and spiritual. The main benefit is that it helps you to be more happy, and brings others around you to be more happy. If we agree that it is a common aim of each of us to strive to be happy, then compassion is one of the main tools for achieving that happiness. It is therefore of utmost importance that we cultivate compassion in our lives and practice compassion every day.
How do we do that? This guide contains 7 different practices that you can try out and perhaps incorporate into your everyday life.
Seven Compassion Practices:
Morning ritual. Greet each morning with a ritual. Try this one: “Today I am fortunate to have woken up, I am alive, I have a precious human life, I am not going to waste it. I am going to use all my energies to develop myself, to expand my heart out to others, to achieve enlightenment for the benefit of all beings, I am going to have kind thoughts towards others, I am not going to get angry or think badly about others, I am going to benefit others as much as I can.” Then, when you’ve done this, try one of the practices below.
Empathy Practice. The first step in cultivating compassion is to develop empathy for your fellow human beings. Many of us believe that we have empathy, and on some level nearly all of us do. But many times we are centered on ourselves (I’m no exception) and we let our sense of empathy get rusty. Try this practice: Imagine that a loved one is suffering. Something terrible has happened to him or her. Now try to imagine the pain they are going through. Imagine the suffering in as much detail as possible. After doing this practice for a couple of weeks, you should try moving on to imagining the suffering of others you know, not just those who are close to you.
Commonalities practice. Instead of recognizing the differences between yourself and others, try to recognize what you have in common. At the root of it all, we are all human beings. We need food, and shelter, and love. We crave attention, and recognition, and affection, and above all, happiness. Reflect on these commonalities you have with every other human being, and ignore the differences. One of my favorite exercises comes from a great article from Ode Magazine — it’s a five-step exercise to try when you meet friends and strangers. Do it discreetly and try to
do all the steps with the same person.
With your attention geared to the other person, tell yourself:
Step 1: “Just like me, this person is seeking happiness in his/her life.”
Step 2: “Just like me, this person is trying to avoid suffering in his/her life.”
Step 3: “Just like me, this person has known sadness, loneliness and despair.”
Step 4: “Just like me, this person is seeking to fill his/her needs.”
Step 5: “Just like me, this person is learning about life.”
Relief of suffering practice. Once you can empathize with another person, and understand his humanity and suffering, the next step is to want that person to be free from suffering. This is the heart of compassion — actually the definition of it. Try this exercise: Imagine the suffering of a human being you’ve met recently. Now imagine that you are the one going through that suffering. Reflect on how much you would like that suffering to end. Reflect on how happy you would be if another human being desired your suffering to end, and acted upon it. Open your heart to that human being and if you feel even a little that you’d want their suffering to end, reflect on that feeling. That’s the feeling that you want to develop. With constant practice, that feeling can be grown and nurtured.
Act of kindness practice. Now that you’ve gotten good at the 4th practice, take the exercise a step further. Imagine again the suffering of someone you know or met recently. Imagine again that you are that person, and are going through that suffering. Now imagine that another human being would like your suffering to end — perhaps your mother or another loved one. What would you like for that person to do to end your suffering?
Now reverse roles: you are the person who desires for the other person’s suffering to end. Imagine that you do something to help ease the suffering, or end it completely. Once you get good at this stage, practice doing something small each day to help end the suffering of others, even in a tiny way - even a smile, or a kind word, or doing an errand or chore, or just talking about a problem with another person. Practice doing something kind to help ease the suffering of others. When you are good at this, find a way to make it a daily practice, and eventually a throughout-the-day practice.
Those who mistreat us practice. The final stage in these compassion practices is to not only want to ease the suffering of those we love and meet, but even those who mistreat us. When we encounter someone who mistreats us, instead of acting in anger, withdraw. Later, when you are calm and more detached, reflect on that person who mistreated you. Try to imagine the background of that person. Try to imagine what that person was taught as a child. Try to imagine the day or week that person was going through, and what kind of bad things had happened to that person. Try to imagine the mood and state of mind that person was in — the suffering that person must have been going through to mistreat you that way. And understand that their action was not about you, but about what they were going through.
Now think some more about the suffering of that poor person, and see if you can imagine trying to stop the suffering of that person. And then reflect that if you mistreated someone, and they acted with kindness and compassion toward you, whether that would make you less likely to mistreat that person the next time, and more likely to be kind to that person. Once you have mastered this practice of reflection, try acting
with compassion and understanding the next time a person treats you. Do it in little doses, until you are good at it. Practice makes perfect.
Evening routine. I highly recommend that you take a few minutes before you go to bed to reflect upon your day. Think about the people you met and talked to, and how you treated each other. Think about your goal that you stated this morning, to act with compassion towards others. How well did you do? What could you do better? What did you learn from your experiences today? And if you have time, try one of the above practices and exercises.
These compassionate practices can be done anywhere, anytime - at work, at home, on the road, while traveling, while at a store, while at the home of a friend or family member. By sandwiching your day with a morning and evening ritual, you can frame your day properly, in an attitude of trying to practice compassion and develop it within yourself. And with practice, you can begin to do it throughout the day, and throughout your lifetime.
This, above all, with bring happiness to your life and to those around you.
