WELLBEING
(Part 1 of 2) Cover story
Can
simply tuning out the world on a regular basis make
you healthier, happier and calmer? Adherents of meditation
say absolutely, but science still needs convincing.
Now, an intriguing study into the mind of a monk might
provide the proof.
He
wore crimson and saffron robes and sported a shiny,
shaved scalp like many of his Tibetan counterparts at
the Shechen Monastery in Nepal. But the monk being tucked
into the claustrophobic tube of the University of Wisconsin's
functional magnetic resonance imaging machine (fMRI)
was no stranger to a science lab.
Matthieu
Ricard - aka Öser in his role as an anonymous test
subject for these unique experiments - was a renowned
molecular biologist with a PhD in cell genetics from
the Institut Pasteur in Paris. But that was before he
embarked on the Buddha path 36 years ago and traded
in his lab coat for holy raiment and a string of mala
beads.
Now,
as a team of scientists and technicians settled behind
a bank of computers, Ricard was being asked to tune
out his audience of academics, as well as the persistent
whirr of the electronic imager, and slip into something
more comfortable - a quiet, meditative state.
Over
three hours, as Ricard dutifully alternated between
periods of meditation and rest, the fMRI recorded video
images of the activity in his brain. It was the first
time scientists had peered so extensively into the mind
of a meditating monk. What they discovered has been
causing them to rethink the workings of the human brain
and its ability to be rewired for health and happiness.
Led
by Dr Richard Davidson, director of the Laboratory for
Affective Neuroscience at the University of Wisconsin,
the fMRI tests with Ricard involved various types of
meditation.
While
engaged in what Buddhists call compassion meditation,
in which the meditator focuses on compassionate thoughts
for a specific individual or all of mankind, Ricard
showed very high levels of activity in the left prefrontal
cortex of his brain (just inside the forehead).
The
prefrontal cortexes are significant players in the regulation
of emotions. In previous tests, Davidson had established
that people who exhibit a higher ratio of persistent
activity in the left prefrontal cortex - an area associated
with feelings of joy, happiness and enthusiasm - have
happier temperaments and tend to bounce back quickly
from negative events. Those who have a higher ratio
of activity in the right prefrontal cortex are more
prone to anxiety, fear, sadness and depression. Most
people fall into the middle ground.
In
a bell curve of subjects Davidson had previously tested,
67 per cent were moderately happy people, while 33 per
cent were on the extreme side of either happy or unhappy.
But
the degree to which the monk's left brain lit up far
surpassed anyone Davidson had measured to date. His
happiness level was, as a Davidson colleague later remarked,
"off the chart". Even when he was not meditating,
his left prefrontal cortex lit up consistently.
Not
long ago, scientists declared that people have a preset
capacity for happiness, which is determined by biology
and changes little whether a person wins the lottery
or experiences a debilitating accident. If someone is
prone to unhappiness and has more activity in their
right prefrontal cortex, winning the lottery might temporarily
spike activity in the left cortex, but it won't tip
them into the company of happier, left-brain people
in the long run.
But
Davidson's tests seem to indicate that happiness isn't
as static as previously believed.
A
significant step towards a scientific understanding
of meditation was taken three years ago, during a series
of extraordinary meetings in Dharamsala, India, between
the Dalai Lama and a group of Western scientists and
philosophers, including Richard Davidson and Owen Flanagan,
professor of philosophy at Duke University in North
Carolina.
For
five days, the Tibetan leader held discussions with
select experts in psychology, philosophy and neuroscience
to examine what science could learn about the mind and
body, particularly emotions, from Buddhism's 2500-year
tradition of meditation.
It
has long been accepted in Eastern cultures that the
mind and body are intricately connected. Centuries of
anecdotal evidence back Buddhist beliefs that the state
of the mind has a direct effect on physical health.
In Tibetan medicine, two of the most important factors
affecting a patient's ability to heal are the mindset
of the doctor and the mindset of the patient.
But
scientists are loath to accept findings not substantiated
in a lab. So the Dalai Lama presented his guests with
a challenge: to scientifically prove that meditation
has medical and emotional benefits, and then to divorce
it from its spiritual roots to make it accessible to
non-Buddhists.
His
aim was to offer the world a practical and secular method
for relieving suffering and finding happiness. But remarkably,
one of the world's most important spiritual leaders
also said that should science disprove the benefits
of meditation, he would be willing to rethink thousands
of years of Buddhist tradition.
"If
science proves facts that conflict with Buddhist understanding,
Buddhism must change accordingly," he said. "We
should always adopt a view that accords with the facts."
The
result of the meeting has been a series of sophisticated
experiments mapping the meditating mind, which have
delivered a number of surprises - even for the monks.
Some of the findings appear in a new book called Destructive
Emotions: A Scientific Dialogue with the Dalai Lama
by Daniel Goleman. Others will be explored at a conference
between scientists, students and the Dalai Lama at the
Massachusetts Institute of Technology next month.
What
preliminary tests show is that as well as helping people
manage destructive emotions like anger, hatred and jealousy,
meditation may have startling effects on the brain's
plasticity - its ability to be moulded or rewired by
experience.
It's
interesting to note that it was compassionate thoughts
that launched Matthieu Ricard into an especially good
mood. Despite being encased in the fMRI for hours, Goleman
reports that Ricard emerged from the gruelling tests
beaming and refreshed.
Anyone
who has ever performed volunteer work or assisted a
friend in need can attest that being compassionate makes
you feel good. Buddhists have long stated that compassion
first benefits the person giving it. Now the pictures
of Ricard's brain seemed to prove it.
But
none of this explained why Ricard was such an extremely
happy camper.
Was
it possible, as Daniel Goleman posed in his book, that
years of meditation had shifted the monk's emotional
setting to make him happier and less flappable than
the average person? Or was his left-brain activity the
result of an exceedingly happy temperament gifted to
him at birth? Was Ricard just an exception?
Or,
another possibility: was it simply the logical outcome
of living the sort of stress-free lifestyle that only
monks and other people in similarly sequestered communities
have?
As
Owen Flanagan's 17-year-old son, who accompanied him
to Dharamsala, put it,
"Dad,
if I wasn't married and didn't have any teenage children,
I'd be happy, too."
To
rule out that years of meditation in a closed community
were needed to experience positive effects, Richard
Davidson conducted an eight-week meditation study with
25 workers at Promega, a biotech firm in Wisconsin.
Prior to the study, the workers, who ranged in age from
23 to 56, exhibited high levels of right-brain activity
and reported feeling stressed-out and unhappy with their
jobs. But after eight weeks of meditation training
and practice, the activity in the left side of their
brains increased significantly, and the workers reported
feeling happier, with a renewed sense of enthusiasm
for their life and work. Four weeks later, the meditators
still showed elevated left-brain activity. The control
group showed no change.
While
more long-term tests are needed to eliminate other factors
that might have contributed to the workers' elevated
moods, scientists are postulating that with prolonged
practice, meditation could alter a person's emotional
setting so that a positive state of mind could become
their emotional default.
The
theory goes like this. Whenever we experience emotions,
we exercise parts of our brain that correspond to those
emotions and build a pattern of circuitry in neural
connections. As the same emotions repeat, the circuitry
associated with them strengthens. Like a river cutting
a path through a gorge, the circuitry etches pathways
in the brain that, over time, become our default pattern
of emotion or temperament. If we experience strong
negative emotions without equally positive ones, the
negative ones will dominate, and will show up as increased
activity in the right side of the brain.
But
Davidson's early research suggests that, just as exercise
strengthens muscles, meditation can strengthen the parts
of the brain that calm anger and fear and elicit happiness.
And, unlike pleasant activities like dancing that result
in temporary mood changes, meditation has a cumulative
effect over time so that the depth of negative emotions
becomes much shallower.
Should
this hypothesis turn out to be true, meditation could
help tip the balance for patients who are prone to depression.
In fact, tests on patients who suffered recurring bouts
of major depression showed that meditation substantially
reduced the risk of relapse from 66 per cent to 37 per
cent.
But
negative emotions don't just affect our happiness and
moods, they may also affect our health. The prefrontal
lobes, along with two other areas of the brain that
play crucial roles in the initiation of emotions - the
amygdala and the hippocampus - are closely tied to blood
pressure, hormones and the immune system.
So
Davidson conducted an additional test with the Promega
workers by giving them influenza vaccinations after
their initial eight-week meditation course. When he
later tested their blood for flu antibodies, the meditation
group had significantly larger amounts of the infection-fighting
protein, indicating a more robust immune system. Those
subjects who exhibited greater increases in left prefrontal
activity after meditation also had the highest levels
of antibodies in their blood.
The
tests with Matthieu Ricard do not represent the first
time science has studied meditating monks with the aim
of divining medical benefits. In the 1980s, Harvard
Medical School cardiologist Herbert Benson, with the
Dalai Lama's help, conducted now-famous tests on monks
in India.
While
engaged in a meditation called g-tummo,
(explanation below) in a room where the temperature
was 4ºC, sheets chilled in 9ºC water were
draped over the monks' shoulders. Instead of shivering
uncontrollably as you might expect them to do, the monks
generated increased body heat to dry the sheets. Other
monks were able to lower their metabolic rate by 64
per cent, a remarkable change given that metabolism
drops only 10 to 15 per cent during sleep.
Earlier,
in 1975, Benson had written the best-selling book The
Relaxation Response based on research into transcendental
meditation (TM) and other forms of contemplative practice,
which showed meditation's effectiveness in treating
stress and high blood pressure.
Benson
agreed to explore the effects of TM after a group of
TM practitioners urged him to do so in the 1970s. In
addition to discovering the physical benefits of TM,
he also discovered that contemplative practices in scores
of other cultures evoked the same physiological responses.
These included decreases in metabolism, heart and breathing
rates and blood pressure, accompanied by alpha brainwaves
(lower frequency brainwaves that occur during relaxation)
and feelings of wellbeing.

All
of these physiological changes are in direct contrast
to the "fight or flight" response that occurs
when we're under stress. When that happens, pupils dilate,
heart and breathing rates increase, and stress chemicals
like cortisol and norepinephrine are released to prepare
the body for a physical response to threats.
The
danger of stress hormones is that when no physical response
occurs to release them, they build up and can undermine
the nervous and immune systems or lead to other health
problems like high blood pressure, heart disease, irritable
bowel syndrome, rheumatoid arthritis, lupus and skin
conditions.
What
Benson discovered was that all types of repetitive prayer
or movement - saying the rosary in Catholicism, the
centring prayer in Protestantism, or davening in Judaism
(which involves rocking to and fro while reciting prayers)
- produced the same physical changes as TM. So did focused
yoga, tai chi, qigong, chanting, the presuggestive stage
of hypnosis and even the concentrated rhythmic beating
of a drum.
So
Benson extracted two steps common to all of them and
created his relaxation technique. It involves repeating
a word, phrase, prayer, sound or even a movement (a
good alternative, he says, for children with attention
deficit disorder) and then disregarding any thoughts
that arise, in order to return focus to the word or
activity. Although similar to Buddhist meditation, which
involves focusing on the in and out breath while disregarding
thoughts that arise, the relaxation technique is a distilled
form of meditation that is designed to achieve medical
benefits rather than spiritual insight.
Proponents
believe that practising the technique 15 to 20 minutes
once or twice a day can help patients reduce stress
and high blood pressure and help treat a variety of
illnesses and disorders, from heart disease to impotence,
PMT to ADD. It has also been used to counter the side
effects of chemotherapy. And workers at ground zero
at the World Trade Centre were taught the technique
to help them cope with their gruesome task.
Recently,
Benson discovered the reason the technique relieves
stress and high blood pressure: it stimulates the release
of nitric oxide in the body, which is a counteragent
to the hormone norepinephrine. Norepinephrine constricts
blood vessels when we're under stress. But nitric oxide
dilates those vessels and restores blood flow. When
stress builds up, however, the release of nitric oxide
is impeded. Nitric oxide is also linked to the production
of
endorphins and other body chemicals that counter pain
and produce feelings of wellbeing. (It's a key factor
in erections, too. Without it, blood flow to the penis
is restricted.)
While
the tests on Ricard endeavour to discover the benefits
of long-term intensive meditation on the mind and body,
the advantage of Benson's relaxation technique is that
it can help even people who do not meditate rigorously.
Paul
Ekman, a psychologist at the University of California
San Francisco, calls Buddhists "gymnasts of the
mind". Like Benson, he suggests that we can greatly
benefit from the mental techniques they can teach us.
Ekman,
a world expert on the science of emotion and nonverbal
communication, also participated in the Dharamsala talks.
He spent decades pioneering the study of facial expressions
among Western populations and African tribes at a time
when no one believed such studies could be useful. Eventually
he ended up training police and FBI forces in reading
the faces of criminal suspects.
He's
met thousands of people during his nearly 50-year career,
but says the Dalai Lama changed his notion of "what
human beings are capable of being".
"It's
amazing how much enjoyment Buddhists have and how much
humour they see in the world," Ekman says. "That
sort of distresses people, seeing them having such a
good time."
A
self-claimed "Buddhist virgin" prior to the
meetings in India, Ekman says he had no interest in
attending the gathering but went because his daughter
was interested in the Free Tibet movement and wanted
to meet the Dalai Lama.
After
reading a few of the Dalai Lama's books, he found remarkable
convergences with his own studies. This led him to launch
a series of tests with Ricard - both he and Davidson
met the monk in Dharamsala - which delivered intriguing
results.
Buddhists
maintain that meditation produces greater self-control
and helps cultivate an internal calmness and happiness
that are our natural state, underneath layers of emotional
combustion and mind chatter. Through persistent practice,
meditators free themselves from the grip of destructive
emotions and face challenges with greater equanimity.
Ekman
was interested in testing the unflappability of Buddhist
monks, so he put Ricard through a series of tests to
measure his startle reflex.
The
startle reflex is an automatic response to loud noise
that every person exhibits, regardless of their day-to-day
exposure to noise. While everyone's face contracts the
same way in the reflex, Ekman says, the degree of reaction
differs, as do the corresponding heart and blood-pressure
rates.
Ekman
says how a person reacts to startling noise is a reliable
indicator of how strongly they experience negative emotions.
A person who reacts intensely and whose heart and breath
take longer to return to normal rates is more prone
to strong feelings of anger and sadness.
To
measure Ricard's response, testers told him they would
count from 10 to zero, then set off a gunshot or firecracker
sound in his ear to which he should not react.
In
previous tests with 5000 subjects, no one could suppress
a reaction to the noise. But Ricard showed no reaction
during one meditation session, though his heart rate
and blood pressure did increase mildly. During another
session, he showed only slight facial expression, while
his heart rate and blood pressure remained the same.
Meditation had, Ricard later told Daniel Goleman, made
the gunshot seem to his mind as neutral as "a bird
crossing the sky".
It's just this type of equanimity and self-control that
prompted authorities at India's largest prison to teach
meditation to inmates. In 1994, the inspector-general
of the prison (which has some 9000 inmates) initiated
a 10-day Vipassana meditation course, aimed at reducing
inmate violence and recidivism by giving prisoners coping
mechanisms for destructive emotions and impulses.
Vipassana
can be a particularly intense Buddhist meditation, designed
to give the meditator deep insight into the mind and
body. It's generally taught at 10-day silent retreats
that involve up to 12 hours of meditation daily, as
well as adherence to a vegetarian diet. After that,
practitioners are encouraged to meditate an hour each
morning and evening.
Paul
Ekman calls doing a Vipassana course and quitting smoking
"the two hardest things I've ever done in my life".
The
1000 participating inmates in the prison course included
many violent offenders, charged with rape, murder, drug
trafficking and terrorist activity. After meditating
for 10 days in a giant tent erected at the prison, the
results were better than anyone expected.
One
inmate who received his release papers before the course
ended refused to leave until he had finished. Many prisoners
reported losing their anger and their desire for revenge
against enemies. And, as the documentary Doing Time,
Doing Vipassana recorded, some were so affected by the
experience that they fell weeping into the arms of their
guards.
In
the end, violence decreased in the prison overall and
relations between guards and prisoners became more harmonious.
The
success in India prompted the National Institutes of
Health in the US to fund a recent University of Washington
study at a jail near Seattle. Inmates were repeat offenders
who had significant drug and alcohol problems, and in
many cases mental disorders, too. Researchers conducted
a controlled study to determine if Vipassana could reduce
recidivism as well as drug and alcohol use.
Three
months after their release from prison, the meditation
inmates showed significant reductions in alcohol-related
problems as well as the use of marijuana, heroin and
crack cocaine. Inmates reported feeling less depressed
and said they felt greater control over their destructive
impulses. Two years after their release, their recidivism
rate was 56 per cent, compared with 75 per cent for
the control group.
While scientists are encouraged by the results of the
recent tests on monks, Ekman says the work to determine
the value of meditation is just beginning.
"If
you really want to find out what are the benefits of
long-term meditation, then you have to study people
before they started meditating and follow them for 20
or 30 years," he says. "I think there are
things we can learn from Buddhist practices. But you
have to evaluate them rigorously."
The
results that scientists found with Matthieu Ricard have
to be repeated with other monks. And so far this hasn't
happened, at least not in the tests that Ekman engineered.
A second monk with the same amount of spiritual training
as Ricard failed to exhibit similar results in the startle
test. Ekman says a few factors could have contributed
to these results, but he's reluctant to discuss them
until more controlled tests are performed.
Owen
Flanagan of Duke University has written about Davidson's
findings in New Scientist magazine. An author of books
on the nature of consciousness, Flanagan practises meditation
himself, but he thinks that, to determine the practical
benefits of long-term meditation for people who aren't
likely to adopt the monkish lifestyle, studies will
have to focus on testing more non-monks as well. Ultimately
he's sceptical that meditation will prove to be the
only cause of happiness in monks.
"I
think if we find out that [Buddhist monks] as a group
are happier, it's not going to have much to do with
meditation," Flanagan says. He thinks it will be
to do with their entire lifestyle. "Studying monks
or nuns who live in a cave is not going to be very helpful
to us, because most of us are not going to live like
that."
While
the recent tests have raised more questions than they
have answered, Paul Ekman is encouraged that the questions
are even being asked. Although he has come around to
acknowledging the legitimacy of meditation as a worthy
area for scientific study, many of his colleagues still
regard it much the way he did before meeting the Dalai
Lama.
"Most
scientists I've spoken to think it's pretty flaky -
this idea that there's something to be learned from
Buddhism - and that [the results are] probably all in
our imagination."
But
Ekman doesn't mind. "Everybody thought I was crazy
for doing the research on facial expression 30 years
ago. Margaret Mead told me I was wasting my time,"
he says.
Of
course, as far as the monks sitting in caves or on mountaintops
are concerned, wasting time is precisely the point.
Om,
what a feeling...
Loosely
defined, meditation is a method of mental training that
involves focused attention for the purpose of spiritual
development or self-actualisation. There are two main
schools of meditation: transcendental meditation, which
came out of India and was popularised by the Hindu monk
Maharishi Mahesh Yogi; and Vipassana, which was developed
by Buddha.
In
TM, which is sometimes called mantra meditation, practitioners
sit for 15 to 20 minutes twice a day, usually with their
eyes closed and hands loosely in their lap, while they
turn their attention inward and repeat a mantra. The
main purpose of the technique is to get the thinking,
active mind to quieten down so that a restful state
can emerge. TM practitioners say they develop better
concentration and memory and become more creative and
self-confident.
The
downside of TM is its history. Its cult-like leader,
the Maharishi, trademarked the TM name and charged students
hundreds of dollars to learn the technique and obtain
a personal mantra.
In
Vipassana, also called mindfulness or insight meditation,
practitioners usually sit for at least an hour a day
and focus on the in and out movement of their breath.
Mindfulness meditation is designed to help meditators
see clearly the patterns of their mind by slowing down
thought processes so they can be observed rather than
acted on. Through this process of sustained self-observation,
meditators cultivate insight into their thoughts, emotions
and actions.
During
the 10-day retreats at which it is taught, students
are prohibited from speaking (inner dialogue is discouraged
as well), reading, watching TV, having sex, or doing
anything else that would distract them from the focused
attention they are supposed to be cultivating.
While
the process can be excruciating, most practitioners
say they emerge feeling a sense of inner balance and
a greater sense of control over their emotions.

**What,
then, is gTummo?
If
you were to place your hands two to three inches below
your navel, you've reached the place on the body where
the gTummo resides. Like the navel, everyone has one.
Some have compared it to the Japanese and Chinese lower
dan tien or hara center, and in fact, the gTummo seems
to be in the same general area. In practice and use,
however, it differs.
Some
have said gTummo is the same as kundalini. Again, I
don't know for sure, but in my experience, the kundalini
experience feels quite different from the gTummo experience.
Kundalini can be hot, like a fire, but it can also be
icy-cold. When it rises, there is a distinct "slithery"
feeling in the spine, which is probably one of the reasons
why kundalini is so often associated with dragons or
serpents. The gTummo is always warm or hot, even though
it flows through the central channel.
