Meditation may help squash anxiety. The practice brings about dramatic effects in as little as a 10-minute session.

 

By: Cary Barbor

In the highlands of the Qinghai-Tibet Plateau, people look at life differently. Upon entering the local Buddhist monastery, there is a spectacular sculpture the size of a large oak. The intricate carving of clouds and patterns are painted in powerful colors. But as soon as winter gives way, this magnificent work will melt to nothing. The sculpture, in fact, is made of butter, and it is one of the highland people’s symbols of the transient nature of life.

And life here is not easy. Villagers bicycle to work before dawn and return home long after sunset. Many live with nothing more than dirt floors and rickety outhouses. Upon entering these modest mud-brick homes, you’ll find no tables or chairs—just a long platform bed, which sleeps a family of eight. However, when the people invite you in for tea, their smiles are wide and welcoming. How do they possess such inner calm in conditions we would call less than ideal?

When villagers cook, sew or plow the fields, they do so in a tranquil state. As an approach to life, weaving meditation seamlessly into almost every action throughout the day seems unfamiliar to Western cultures. Is there something we can glean from this way of life that will improve our own? The romantic notion of quitting everything and joining Tibetan monks on a mountaintop is not the only way to meditate. You don’t need to quit your job, give up your possessions and spend 30 years chanting. Recent research indicates that meditating brings about dramatic effects in as little as a 10-minute session. Several studies have demonstrated that subjects who meditated for a short time showed increased alpha waves (the relaxed brain waves) and decreased anxiety and depression.

To explore exactly what part of the brain meditation acts on, researchers at Harvard Medical School used MRI technology on participants to monitor brain activity while they meditated. They found that it activates the sections of the brain in charge of the autonomic nervous system, which governs the functions in our bodies that we can’t control, such as digestion and blood pressure. These are also the functions that are often compromised by stress. It makes sense, then, that modulating these functions would help to ward off stress-related conditions such as heart disease, digestive problems and infertility.

Meditation: What is It?

Aside from determining its physiological effects, defining the actual act of meditation can be as elusive as imagining the sound of one hand clapping. In his book, “What is Meditation?”  (Shambhala Publications, 1999), Rob Nairn talks about it as a state of “bare attention.” He explains, “It is a highly alert and skillful state of mind because it requires one to remain psychologically present and ‘with’ whatever happens in and around one without adding to or subtracting from it in any way.”

The physical act of meditation generally consists of simply sitting quietly, focusing on one’s breath, a word or phrase. However, a meditator may also be walking or standing. It isn’t unusual, in fact, to see a meditating monk in the highlands walking a few steps and then lying prostrate over and over again until he reaches his destination many miles away.

There are many traditions and countless ways to practice meditation, and perhaps because of its polymorphous nature new meditators wonder whether they are doing it correctly. According to Roger Thomson, Ph.D., a psychologist in private practice in Chicago and a Zen meditator, there is one way to know for sure: “If you’re feeling better at the end, you are probably doing it right.”

Thomson makes it sound easy, but many people can’t seem to get the hang of it, no matter how often they try. “It can be difficult,” says Steven Hendlin, Ph.D., a clinical psychologist in Irvine, California. “It may be a struggle to overcome the internal chatter that we all experience.”

Seeking methods for quieting that internal chatter and reducing stress are what initially attract many people to meditation. “It is a very effective stress-reducer, which is a way into the practice for many people,” says Thomson, who sometimes refers clients to meditation. “If someone is struggling with feelings of anxiety, he or she may benefit from its calming aspects. And it’s absolutely facilitative of mental health because it brings about a higher level of self-acceptance and insight about oneself.”

But greater awareness about oneself can be a double-edged sword. Mark Epstein, M.D., a New York City psychiatrist in private practice and a meditation practitioner, extends a caution about one of the ironies of meditating. “It could actually raise your level of anxiety if there are certain feelings you are not owning.” In other words, there’s nowhere to hide when you’re practicing “bare attention.” And this, for some people, is both the good and the bad news.

That’s why some experts suggest marrying meditation to psychotherapy. “Both allow the person to be present for the moment, open and nondefensive,” says Thomson, who explores the complementary nature of the two in a paper published in the American Journal of Psychotherapy. “In both meditation and psychotherapy, we are trying not to get caught up in internal preoccupation, but to be intimately present with what is happening here and now.”

To explain his thoughts on the connection, Thomson compares Zen to relational psychoanalytical theories. He writes that it “encourages its practitioners to become aware of the fundamentally distorted aspects of an overly individualistic view of human experience. Recognizing that the true nature of all individuals is emphatically non-individual, neither lasting nor separate, is the wisdom of Zen.”

Silence and Science

Certainly anything that helps us fight stress is a welcome tool. But what else might meditation be doing for us? Since researchers like Herbert Benson, M.D. began amassing data, many studies have shown that indeed meditation has not only a mental but a profound physiological effect on the body. Studies have shown that, among other benefits, meditation can help reverse heart disease, the number-one killer in the U.S. It can reduce pain and enhance the body’s immune system, enabling it to better fight disease.

More new research offers additional encouragement. In a study published last year in the journal Stroke, 60 African-Americans with atherosclerosis, or hardening of the arteries, practiced meditation for six to nine months. (African-Americans are twice as likely to die from cardiovascular disease as are whites.) The meditators showed a marked decrease in the thickness of their artery walls, while the nonmeditators actually showed an increase. The change for the meditation group could potentially bring about an 11 percent decrease in the risk of heart attack and an 8 percent to 15 percent decrease in the risk of stroke.

A second study, published last year in Psychosomatic Medicine, taught a randomized group of 90 cancer patients mindful meditation (another type of practice). After seven weeks, those who had meditated reported that they were significantly less depressed, anxious, angry and confused than the control group, which hadn’t practiced meditation. The meditators also had more energy and fewer heart and gastrointestinal problems than did the other group.

Other recent research has looked at precisely what happens during meditation that allows it to cause these positive physical changes. Researchers at the Maharishi School of Management in Fairfield, Iowa, found that meditation has a pervasive effect on stress. They looked at a group of people who had meditated for four months and found that they produced less of the stress hormone cortisol. They were therefore better able to adapt to stress in their lives, no matter what their circumstances were.

Diana Adile Kirschner, Ph.D., a Philadelphia-area clinical psychologist, sometimes refers her clients to learn meditation and has seen firsthand how helpful it can be. “Not only is meditation an absolutely marvelous destressor, it helps people better relate to one another,” she says. “I can tell when clients are following through with meditation. For instance, I had a couple who consistently bickered. After they started meditating, they came in less angry, more self-reflective and more loving.”

So why aren’t more people taking up the practice? “Because it puts us in the middle of ourselves, which is not always where we want to be,” suggests Thomson. “Often, we want to fix things rather than accept them the way they are. Many of us feel as though we can’t afford the time and energy to meditate, when in fact we can’t afford not to.”

Epstein and several other experts feel that meditation’s effectiveness has to do with putting aside attachment to one’s ego. As he says, “When you look directly at a star at night, it’s difficult to see. But when you look away slightly, it comes into focus. I find it to be the same way with the ego and meditating. When one zeroes in on a sense of self through a practice of meditation, the self-important ego paradoxically becomes elusive. You become more aware that you are interconnected with other beings, and you can better put your own worries into their proper perspective.”

A group of elderly Chinese maintain their connection by meeting every daybreak in the village common in Monterey Park, California. They swoop their arms and stretch their torsos in graceful harmony, and then stand absolutely still, simply meditating. Only puffs of warm air flow from their nostrils. All of them look vibrant and relatively young, when in fact they are well into their years.

While western scientists are still exploring exactly how and why meditation works, we already know that it has both physiological and psychological benefits. And many therapists consider it a valid complement to more traditional therapies. So perhaps we should simply take Thomson’s advice—and the Tibetans’ lead—and do what makes us feel better in the end.

One Response to The Science of Meditation

    Previous comments to date:

    Yoga (Application) which was based on the control of the body physically and implied that a perfect control over the body and the senses led to knowledge of the ultimate reality. A detailed anatomical knowledge of the human body was necessary to the advancement of yoga and therefore those practising yoga had to keep in touch with medical knowledge. (Romila Thapar, A History of India, volume one).
    I suggest : Mind and brain are two distinct things. Brain is anatomical entity whereas mind is functional entity. Mind can be defined as the function of autonomic nervous system (ANS). It is claimed that mind can be brought under conscious control through the practice of meditation. But how? ANS is largely under hypothalamic control which is situated very close to optic chiasma (sixth chakra or ajna chakra). Protracted practice of concentration to meditate at this region brings functions of ANS say mind under one’s conscious control.
    ANS is further divided into parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS). On the basis of these facts I have discovered a mathematical relationship for spiritual quotient (S.Q.). Spiritual Quotient can be expressed mathematically as the ratio of Parasympathetic dominance to Sympathetic dominance. PSNS dominates during meditative calm and SNS dominates during stress. In this formula we assign numerical values to the physiological parameters activated or suppressed during autonomic mobilization and put in the formula to describe the state of mind of an individual and also infer his/her level of consciousness.
    Meditation is the art of looking within and science of doing nothing. We don’t use anything in meditation. We just try to concentrate to meditate at some point in human anatomy known as ‘chakra’ in Indian System of Yoga. The current of mind is flowing outward through the senses and unconsciously. The mind comes at rest gradually through regular practice of meditation. Then comes self realization.
    Protracted practice of meditation under qualified guidance will help to manage all sort of psychological problems.
    Emotional Quotient can also be expressed mathematically as the product of I.Q. and Wisdom Factor.E.Q. stands for Emotional Quotient. An intelligent person may not be wise. But a wise man will always be intelligent. An intelligent person having certain level of positive emotions can be said as wise. An intelligent person lacking wisdom will turn autocrat. A wise man will always be a democrat who respects others existence.
    Some one has raised the doubt that how could be the Wisdom quantified? The answer is simple -if Mental Age of I.Q. can be quantified then Wisdom can also be quantified, of course, comparatively with more efforts.

    Fascinating comment, Anirudh. Thank you!
    I agree with you that mind and brain are indeed separate, although I hadn’t thought of mind in the terms you’ve described.
    You make a sound case for the quantification of such esoteric qualities as spirituality and wisdom. I would be interested in seeing an example of your calculations of SQ and WQ. If you would care to post it here, or provide a link so that others might see it, that would be excellent.

    Thank you Dear Keena
    PRACTICE OF YOGA AND DEVELOPMENT OF SPIRITUAL QUOTIENT
    Religion and Yoga reflect identical meaning. Religion (re-ligare) means union again with Ultimate Reality or binding back to Absolute. Yoga is the derivative of Sanskrit root ‘yuj’ which means yoking of power of body, mind and soul. Yoga primarily consists of concentration, meditation and realization apart from practicing asans, mudras and breath control which help to achieve concentration and physical and emotional well-being. Yoga is experimental technique of spiritualism. Religion is blend of ritual and spiritual. Rituals dominate religion these days. Whereas rituals are altogether not necessary for practicing yoga.
    Yoga in India has been practiced since the dawn of the human civilization, according to Hindu mythology millions of year back.
    In Bhagavad-Gita Lord SriKrishna says to Arjuna:
    “I taught this immortal Yoga to Vivasvan (sun-god), Vivasvan conveyed it to Manu(his son), and Manu imparted it to (his son) Iksvaku. Thus transmitted to succession from father to son, Arjuna, this Yoga remained known to the Rajarisis (royal sages). It has however long since disappeared from this earth. The same ancient Yoga has this day been imparted to you by Me, because you are My devotee and friend, and also because this is a supreme secret”.
    At this Arjuna said: You are of recent origin while the birth of Vivasvan dates back to remote antiquity. How, then, I am to believe that you taught this Yoga at the beginning of creation? Lord SriKrishna said: Arjuna, you and I have passed through many births. I remember them all, you do not remember.
    Famous historian Romila Thapar has described in her book A History of India about the status of Yoga in 300-700 A.D. She writes: “Yoga (Application) which was based on the control of the body physically and implied that a perfect control over the body and the senses led to knowledge of the ultimate reality. A detailed anatomical knowledge of the human body was necessary to the advancement of yoga and therefore those practising yoga had to keep in touch with medical knowledge.”
    As far as anatomical knowledge of human body is concerned it is very much required for the optimum result during practice of Yoga. Yoga system has very close connection with the human anatomy i.e. chakra or nerve centres distributed along the spinal column and in brain region.
    Besides, connection chakras with the practice of Yoga, chakra has also great role in the development of personality. People do not realise that personalities can grow to include a balance of all the six chakras. Jung referred to this growth process as “individuation”, and associated it with life’s spiritual dimension. Danah Zohar evolves a model of spiritual quotient (sq) based on the six petals of a lotus and its centre, corresponding to the seven chakras described by the Hinduism’s Kundalini Yoga, as an aid to the process of individuation in the mid-1990s. Contribution of Danah Zohar for coining the term spiritual quotient for the first time is immense. But she did not establish any mathematical relationship, which is very much required, for this quotient.
    Deepak Chopra has given a formula of spiritual quotient in terms of Deed (D) and Ego (E). According to Deepak Chopra S.Q. =D/E. He (2006) writes: If Vedanta is right and there is only one reality, then all desires must follow the same mechanics, desires arise and are fulfilled in consciousness. Making yourself happy involves ….. I have a ” Spiritual Quotient” where SQ = D/E. Where D = Deeds and E = Ego. Now you can ONLY have an SQ = infinity when E = 0. If E is little even then SQ is approaching infinity (or one is close to be a “Great Master”) but not actually “Pure .This appears to be very fascinating but it is highly abstract which cannot be measured experimentally, accurately and precisely. However, this formula has immense value to understand S.Q.
    I have also discovered a mathematical relationship for S.Q about eight years back in 2001. I have used physiological parameters which can be measured accurately and precisely and can be tested and verified experimentally. According to this formula S.Q. can be expressed as the ratio of parasympathetic dominance (P.D.) to sympathetic dominance (S.D.). Parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS) are the two parts of the autonomic nervous system (ANS) which is largely under hypothalamic control. Hypothalamus is situated very close to the Sixth Chakra. During practice of meditation at Sixth Chakra these centres are galvanized which has very positive effect on practitioners spiritual, emotional, psychological and physical well being.
    According to this relationship spiritual quotient can be written as:
    S.Q. = P.D./S.D.
    If the value of S.Q. comes >1 (greater than one), it can be assumed that the person is moving towards self-realisation and if the value of S.Q. comes <1 (smaller than one) it can be predicted that the person is living under stress.
    There are various types of meditation available, which are being practiced by sages, saints, seers and others. The difference in various versions lies in the fact that these practices involve concentration to meditate at different centres known as Chakra in Yoga System. These chakras are, in fact, energy centres which correspond to nerve centres distributed along the spinal column and in brain region.
    Some practitioners start to meditate at Basic/Root Chakra (Muladhara) – situated at the base of spine, some at Heart Chakra (Anahata Chakra), some at Ajna Chakra – Optic Chiasma – Master Chakra and some from even higher centres situated in the brain region. Among all these types of meditation, practice at sixth chakra is considered to be the most ideal which brings about optimum results.
    Sixth Chakra is situated very close to hypothalamus. The hypothalamus is a portion of brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link nervous system to the endocrine system via the pituitary glands.
    Autonomic nervous system (ANS) is largely under hypothalamic control. ANS consists of parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS). PSNS is activated during meditative calm and during stress SNS is activated. When PSNS is activated, heart rate, breathing rate, blood pressure decreased. Supply of blood in the digestive tract increased. When SNS is activated heart rate, breathing rate, blood pressure increased. Supply of blood to the muscles and exterior organs increased and to the digestive tract decreased. In addition to these, there are many other parameters which can be compared. Parasympathetic Dominance (P.D.) is the state of PSNS activation and Sympathetic Dominance (S.D.) is the state of SNS activation. Instruments are available in medical science to measure these parameters.
    Now we can assign numerical value to each parameter. Then put the value in the formula for S.Q. and see the result. We can show the calculation as mentioned below:
    S.Q.= P.D./S.D. = Σ X / Σ Y
    Where X=x1+x2+x3+ …….
    And Y=y1+y2+y3+…….
    During PSNS activation (P.D.), we assign ‘1’ to each parameter (x1+x2+x3+…..) and ‘0’ to each parameter (y1+y2+y3+…..). During SNS activation (S.D.), we assign ‘1’ to each parameter (y1+y2+y3+…) and ‘0’ to each parameter (x1+x2+x3+….).
    By putting the numerical value, thus achieved, in the above formula for S.Q. we can calculate the Spiritual Quotient of an individual.
    Wish you a very happy and prosperous new year, Dear Keena. thanks.
