Definition
Meditation is a practice of concentrated focus upon
a sound, object, visualization, the breath, movement, or
attention itself in order to increase awareness of the present
moment, reduce stress, promote relaxation, and enhance
personal and spiritual growth.
Origins
Meditation techniques have been practiced for millennia.
Originally, they were intended to develop spiritual
understanding, awareness, and direct experience of ultimate
reality. The many different religious traditions in
the world have given rise to a rich variety of meditative
practices. These include the contemplative practices of
Christian religious orders, the Buddhist practice of sitting
meditation, and the whirling movements of the Sufi
dervishes. Although meditation is an important spiritual
practice in many religious and spiritual traditions, it can
be practiced by anyone regardless of their religious or
cultural background to relieve stress and pain.
As Western medical practitioners begin to understand
the mind’s role in health and disease, there has
been more interest in the use of meditation in medicine.
Meditative practices are increasingly offered in medical
clinics and hospitals as a tool for improving health and
quality of life. Meditation has been used as the primary
therapy for treating certain diseases; as an additional
therapy in a comprehensive treatment plan; and as a
means of improving the quality of life of people with debilitating,
chronic, or terminal illnesses.
Benefits
Meditation benefits people with or without acute
medical illness or stress. People who meditate regularly
have been shown to feel less anxiety and depression.
They also report that they experience more enjoyment
and appreciation of life and that their relationships with
others are improved. Meditation produces a state of deep
relaxation and a sense of balance or equanimity. According
to Michael J. Baime, “Meditation cultivates an emotional
stability that allows the meditator to experience intense
emotions fully while simultaneously maintaining
perspective on them.” Out of this experience of emotional
stability, one may gain greater insight and understanding
about one’s thoughts, feelings, and actions. This insight
in turn offers the possibility to feel more confident and in
control of life. Meditation facilitates a greater sense of
calmness, empathy, and acceptance of self and others.
Meditation can be used with other forms of medical
treatment and is an important complementary therapy for
both the treatment and prevention of many stress-related
conditions. Regular meditation can reduce the number of
symptoms experienced by patients with a wide range of
illnesses and disorders. Based upon clinical evidence as
well as theoretical understanding, meditation is considered
to be one of the better therapies for panic disorder,
generalized anxiety disorder, substance dependence and
abuse, ulcers, colitis, chronic pain, psoriasis, and dysthymic
disorder. It is considered to be a valuable adjunctive
therapy for moderate hypertension (high blood
pressure), prevention of cardiac arrest (heart attack),
prevention of atherosclerosis (hardening of arteries),
arthritis (including fibromyalgia), cancer, insomnia,
migraine, and prevention of stroke. Meditation may also
be a valuable complementary therapy for allergies and
asthma because of the role stress plays in these conditions.
Meditative practices have been reported to improve
function or reduce symptoms in patients with
some neurological disorders as well. These include people
with Parkinson’s disease, people who experience
fatigue with multiple sclerosis, and people with epilepsy
who are resistant to standard treatment.
Overall, a 1995 report to the National Institutes of
Health on alternative medicine concluded that, “More
than 30 years of research, as well as the experience of a
large and growing number of individuals and health care
providers, suggests that meditation and similar forms of
relaxation can lead to better health, higher quality of life,
and lowered health care costs.” A study of health care
professionals published in 2002 indicates that the majority
of physicians, nurses, and occupational therapists in
the United States accept meditation as a beneficial adjunct
to conventional medical or surgical treatments.
Description
Sitting meditation is generally done in an upright
seated position, either in a chair or cross-legged on a
cushion on the floor. The spine is straight yet relaxed.
Sometimes the eyes are closed. Other times the eyes are
open and gazing softly into the distance or at an object.
Depending on the type of meditation, the meditator may
be concentrating on the sensation of the movement of the
breath, counting the breath, silently repeating a sound,
chanting, visualizing an image, focusing awareness on
the center of the body, opening to all sensory experiences
including thoughts, or performing stylized ritual movements
with the hands.
Movement meditation can be spontaneous and freeform
or involve highly structured, choreographed, repetitive
patterns. Movement meditation is particularly helpful
for those people who find it difficult to remain still.
Generally speaking, there are two main types of meditation.
These types are concentration meditation and
mindfulness meditation. Concentration meditation practices
involve focusing attention on a single object. Objects
of meditation can include the breath, an inner or external
image, a movement pattern (as in tai chi or yoga), or a
sound, word, or phrase that is repeated silently (mantra).
The purpose of concentrative practices is to learn to focus
one’s attention or develop concentration. When thoughts
or emotions arise, the meditator gently directs the mind
back to the original object of concentration.
Mindfulness meditation practices involve becoming
aware of the entire field of attention. The meditator is instructed
to be aware of all thoughts, feelings, perceptions,
or sensations as they arise in each moment. Mindfulness
meditation practices are enhanced by the meditator’s
ability to focus and quiet the mind. Many meditation
practices are a blend of these two forms.
The study and application of meditation to health
care has focused on three specific approaches: 1. transcendental
meditation (TM); 2. The “relaxation response,”
a general approach to meditation developed by
Dr. Herbert Benson; and 3. mindfulness meditation,
specifically the program of mindfulness-based stress reduction
(MBSR) developed by Jon Kabat-Zinn.
Transcendental meditation
TM has its origins in the Vedic tradition of India and
was introduced to the West by Maharishi Mahesh Yogi.
TM has been taught to somewhere between two and four
million people. It is one of the most widely practiced
forms of meditation in the West. TM has been studied
many times; these studies have produced much of the information
about the physiology of meditation. In TM,
the meditator sits with closed eyes and concentrates on a
single syllable or word (mantra) for 20 minutes at a time,
twice a day. When thoughts or feelings arise, the attention
is brought back to the mantra. According to Charles
Alexander, an important TM researcher, “During TM,
ordinary waking mental activity is said to settle down,
until even the subtlest thought is transcended and a completely
unified wholeness of awareness..is experienced.
In this silent, self-referential state of pure wakefulness,
consciousness is fully awake to itself alone..” TM supporters
believe that TM practices are more beneficial
than other meditation practices. A group of Australian
researchers has recently recommended TM as a preventive
strategy for heart disease.
The relaxation response
The relaxation response involves a similar form of
mental focusing. Dr. Herbert Benson, one of the first
Western doctors to conduct research on the effects of
meditation, developed this approach after observing the
profound health benefits of a state of bodily calm he
calls “the relaxation response.” In order to elicit this response
in the body, he teaches patients to focus upon the
repetition of a word, sound, prayer, phrase, or movement
activity (including swimming, jogging, yoga, and even
knitting) for 10–20 minutes at a time, twice a day. Patients
are also taught not to pay attention to distracting
thoughts and to return their focus to the original repetition.
The choice of the focused repetition is up to the individual.
Instead of Sanskrit terms, the meditator can
choose what is personally meaningful, such as a phrase
from a prayer.
Mindfulness meditation
Mindfulness meditation comes out of traditional
Buddhist meditation practices. Psychologist Jon Kabat-
Zinn has been instrumental in bringing this form of meditation
into medical settings. In formal mindfulness practice,
the meditator sits with eyes closed, focusing the attention
on the sensations and movement of the breath for
approximately 45–60 minutes at a time, at least once a
day. Informal mindfulness practice involves bringing
awareness to every activity in daily life. Wandering
thoughts or distracting feelings are simply noticed without
resisting or reacting to them. The essence of mindfulness
meditation is not what one focuses on but rather
the quality of awareness the meditator brings to each
moment. According to Kabat-Zinn, “It is this investigative,
discerning observation of whatever comes up in the
present moment that is the hallmark of mindfulness and
differentiates it most from other forms of meditation.
The goal of mindfulness is for you to be more aware,
more in touch with life and whatever is happening in
your own body and mind at the time it is happening—
that is, the present moment.” The MBSR program consists
of a series of classes involving meditation, movement,
and group process. There are over 240 MBSR programs
offered in health care settings around the world.
Meditation is not considered a medical procedure or
intervention by most insurers. Many patients pay for
meditation training themselves. Frequently, religious
groups or meditation centers offer meditation instruction
free of charge or for a nominal donation. Hospitals may
offer MBSR classes at a reduced rate for their patients
and a slightly higher rate for the general public.
Precautions
Meditation appears to be safe for most people. There
are, however, case reports and studies noting some adverse
effects. Thirty-three to 50% of the people participating
in long silent meditation retreats (two weeks to three
months) reported increased tension, anxiety, confusion,
and depression. On the other hand, most of these same
people also reported very positive effects from their meditation
practice. Kabat-Zinn notes that these studies fail to
differentiate between serious psychiatric disturbances and
normal emotional mood swings. These studies do suggest,
however, that meditation may not be recommended for
people with psychotic disorders, severe depression, and
other severe personality disorders unless they are also receiving
psychological or medical treatment.
Side effects
There are no reported side effects from meditation
except for positive benefits.
Research & general acceptance
The scientific study of the physiological effects of
meditation began in the early 1960s. These studies prove
that meditation affects metabolism, the endocrine system,
the central nervous system, and the autonomic nervous
system. In one study, three advanced practitioners of Tibetan
Buddhist meditation practices demonstrated the ability
to increase “inner heat” as much as 61%. During a different
meditative practice they were able to dramatically
slow down the rate at which their bodies consumed oxygen.
Preliminary research shows that mindfulness meditation
is associated with increased levels of melatonin.
These findings suggest a potential role for meditation in
the treatment and prevention of breast and prostrate cancer.
Despite the inherent difficulties in designing research
studies, there is a large amount of evidence of the
medical benefits of meditation. Meditation is particularly
effective as a treatment for chronic pain. Studies have
shown meditation reduces symptoms of pain and painrelated
drug use. In a four-year follow-up study, the majority
of patients in a MBSR program reported “moderate
to great improvement” in pain as a result of participation
in the program.
Meditation has long been recommended as a treatment
for high blood pressure; however, there is a debate
over the amount of benefit that meditation offers. Although
most studies show a reduction in blood pressure
with meditation, medication is still more effective at
lowering high blood pressure.
Meditation may also be an effective treatment for
coronary artery disease. A study of 21 patients practicing
TM for eight months showed increases in their amount
of exercise tolerance, amount of workload, and a delay
in the onset of ST-segment depression. Meditation is also
an important part of Dean Ornish’s program, which has
been proven to reverse coronary artery disease.
Research also suggests that meditation is effective in
the treatment of chemical dependency. Gelderloos and
others reviewed 24 studies and reported that all of them
showed that TM is helpful in programs to stop smoking
and also in programs for drug and alcohol abuse.
Studies also imply that meditation is helpful in reducing
symptoms of anxiety and in treating anxiety-related
disorders. Furthermore, a study in 1998 of 37 psoriasis
patients showed that those practicing mindfulness
meditation had more rapid clearing of their skin condition,
with standard UV light treatment, than the control
subjects. Another study found that meditation decreased
the symptoms of fibromyalgia; over half of the patients
reported significant improvement. Research by a group
of ophthalmologists indicates that nearly 60% of a group
of patients being treated for glaucoma found meditation
helpful in coping with their eye disorder. In addition,
meditation was one of several stress management techniques
used in a small study of HIV-positive men. The
study showed improvements in the T-cell counts of the
men, as well as in several psychological measures of
well-being.
