What is meditation? Definitions Stability of mind Wavering of mind is stopped Concentration on one target Unified thought process Thoughtlessness Introspection Lack of activity To leave, to give away Mental aerobics Intentional self regulation Dedication Stay connected Patanjali Buddha Narad
Slide 9-

Definition : Thinking deeply or spiritually about a subject It is a complex cognitive task It is more than relaxation, concentration, contemplation or posturing Frees the mind from distractions and allows for communication with the “Master Within” The ultimate goal is ILLUMINATION : ENLIGHTENMENT What is meditation? Definitions
Slide 10-

Meditation : advantages Physical, mental and emotional health. Cure / control of psychosomatic disorders including high blood pressure, coronary artery disease, DM, asthma, rheumatism etc. Stress relief. Spiritual health. Better concentration and sharpness. Produces relaxation and reduces reactivity. Improves Job performance. Interpersonal relations.
Slide 11-

Brings change of attitude Inner peace, patience and happiness. Cultivates and promotes positive emotions and removes negative thoughts. Helps in controlling anger and conquering fear. Brings control over thought process. Improves quality of life. Intuitive knowledge, healing power, magnetic personality and occult powers. Meditation : advantages
Slide 12-

Meditation is an antidote to stress The neuro chemistry and neuro physiology of meditation is just the reverse of stress. Stress : Over activity of Sympathetic system. Meditation: Over activity of Parasympathetic system.
Slide 13-

Caution However, it is not a push button system, you need patience. Hence there is a 90 to 95% -drop out rate. You need to have right guide, right method, correct understanding, appropriate place, constant practice, extreme faith and full conviction. Please do not sleep. Meditation industry is at height, because of commercialization, so one should be careful. Not to make comparisons, All systems are great
Slide 14-

Meditation is hard work. It demands the highest form of discipline which comes through constant awareness, not only of the things about you outwardly, but also inwardly. - J. Krishnamurti

Basic Instructions for Meditation To bring the attention to the breath, but not to control the breathing. It is not pranayama. Give full attention to the feeling of the breath as it goes in and out. Dwell in the present, moment by moment, breath by breath. Observe your mind with moment-to-moment awareness. Anapan Sati
Slide 23-

When attention wanders, note it and then gently bring awareness back to the breath. Why breathing ? Truth, vital, secular, always with you, present tense, carrier of mind – Emotions, thoughts, and perversions Continue to watch the breath, accepting each moment as it is for 1 hour. Not to loose single breath - The power of ‘NOW’ - The concept of ‘VOID’ When breathing takes consciousness into each cell, there is a vital dance Basic Instructions for Meditation
Slide 24-

Meditation-Techniques Smriti Upasthan : Observation & awareness of thoughts Budhha, Krishnamurti Avoid conflict with mind The root cause of miseries is thoughts Study beginning, end, structure & content of thoughts. Pl. do not criticize Observe & know your thoughts Study movement of mind and feel separated This will lead to detachment with thoughts Becoming aware of one’s consciousness Observer will realize that himself is being observed Purnayoga : Maharishi Aurobindo’s method of combination Yoga Empty your thoughts & know your mind
Slide 25-

Meditation Jaindhyana Jain religion is Bhavadharma, so meditation is of utmost importance. Dharmadhyana & shukladhyana… excellent remedy for all types of health. Several types of meditations. Samayik & kayotsarga are super meditations. Preksha, vipashyana, granthibheda Atmadhyana.
Slide 26-

Atmadhyana Meditating on the soul is one of the best meditations. To remain constantly aware of the soul and its characteristics and its functions. To dissociate soul from the body at every moment and the sentinence – the application of knowledge is the ultimate meditation. Samayam api ma pamayae GOYAMA !
Slide 27-

Mindfulness Practice Observing the body and mind intentionally Letting experiences unfold from moment to moment and accepting them as they are. Observing thoughts without getting caught up in them. No effort to control anything except the focus and direction of the attention. Not a passive process, yet does not involve trying to get anywhere. Eating meditation, sitting meditation, working meditation and meditation during each act is the goal of mindfulness practice.
Slide 35-

Rule No. 1 Wherever there is body, mind should also be there without any exception Rule No. 2 Develop wakeful plain observorship (Sakshibhav or Drushtabhav) Rule No. 3 Know your soul with your own soul.

Slide 46-

Benefits of meditation Oxygen consumption is reduced by 16%, even greater than the reduction of 12% in sleep Neural structures that are intimately related to the control of the autonomic nervous system are activated Diurnal, cyclic secretion of stress hormones (adrenocorticotrophic hormone, cortisol and beta-endorphin) is absent
Slide 47-

STATISTICS Physicians, Psychotherapists, and other Professionals are increasingly adding Meditative Techniques to their practice. Over six thousand Physicians have begun the practice of Transcendental Meditation and regularly recommend the TM technique to their patients. Many Physicians consider Meditation a key element of an Integrated Health Program.
Slide 48-

Health Conditions in which Yoga may help heal or treat Arthritis Allergies Asthma Hypertension Coronary Artery Disease Irritable Bowel Syndrome Heartburn (GERD) Constipation Tension Headaches and Migraines PMS and Menstrual Discomfort Menopause Pain of the Back, Hips, Knees Depression & Anxiety Substance Abuse Skin Disorders Chronic Fatigue Syndrome Overweight Sleep Problems
Slide 49-

Researching the Benefits of on Meditation : With 7 weeks of meditation, cancer patients decreased their degree of depression, anxiety, anger, confusion, and chest and stomach symptoms by 50% - and felt more vigor. With 10 weeks of meditation, 2/3’s of chronic pain patients had a 30% reduction in pain, and half had more than a 50% reduction. With 10 weeks of meditation, chronic pain patients had less pain, less mood disturbances, used less pain medication, and could be more active. The benefits were still present one year later. Three years after an 8-week meditation instruction, patients with anxiety and panic disorders still showed a benefit. All patients with fibromyalgia who meditated for 10 weeks improved, and over half showed moderate to marked improvement in pain, fatigue and quality of sleep. Medical benefits of meditation
Slide 50-

Meditation has been found to be quite useful in most of the psychosomatic disorders including asthma, rheumatism, gut problems, blood pressure, diabetes etc. With 6 weeks of meditation irritable bowel syndrome patients had less flatulance, belching, bloating and diarrhea. Even though daily fluctuations in cortisol are unchanged, people who meditate don’t have the daily fluctuations in the cortisol-stimulating hormone (ACTH), or beta-endorphins, suggesting a change in feedback sensitivity. People trained in and performing an imagery-based relaxation prior to injection, had less inflammatory reaction to chili pepper “extract” (capsaicin) injected under the skin. With 6 months of meditation, athletes had less increase in the CD8+ suppressor T cell response to strenuous physical stress, improving the immune system’s helper to suppressor cell ratio. It also reduces post-traumatic stress. Medical benefits of meditation
Slide 51-

Patients who meditated during ultraviolet light treatment for psoriasis had quicker clearing of their skin disease. With 6 months of meditating for 20 minutes twice a day, hypertensive African Americans had a decrease in the carotid artery wall thickness. With 4 years of daily meditation, coronary artery narrowing showed regression rather than progression. Over a 5 year period, people who meditated had over 50% less doctor’s office visits, and an average of 50% less hospital admissions (including a reduction all 17 major treatment categories such as benign and malignant tumors, heart disease, infectious disease, and nervous system disorders). Only childbirth rates were the unchanged. Medical benefits of meditation
Slide 52-

Relative contraindications of meditation Psychosis Severe depression Confusional states Extreme anxiety Dementias
Slide 53-

Physiology of Meditation Meditation produces a specific physiological response pattern that involves various biological systems. Mechanisms producing meditative effects include metabolic, autonomic, endocrine, neurological, and psychological manifestation. Physiological response to meditation occurs on a multidimensional, interactive basis.
Slide 54-

Neuro Electrical Changes During Meditation
Slide 55-

Neuroelectrical Effects Mediation (the Fourth State) was shown to - increase Alpha (8-13 Hz or cycles per second) production - increase Theta (4-7 Hz) production - increase high Beta (20 - 40 Hz) activity ( with experienced meditators). Alpha patterns are associated with calm and focused attention. Theta patterns are associated with reverie, imagery, and creativity. High Beta activity is associated with highly focused concentration
Slide 56-

Important features of EEG changes related to meditation are : Establishing alpha activity in spite of open eyes Increased amplitude of alpha activity Slower frequency of alpha rhythm Rhythmical theta waves Increased synchronization (hypersynchronization) Dissociation of perception from the external sense organs Transcendent signal Occasional fast wave activity
Slide 57-

Decrease in Beta-wave activity after meditation
Slide 58-

ALPHA brainwaves are the brainwaves of relaxed detached awareness, visualization, sensory imagery and light reverie. Ranging between about 8 cycles per second and 13 cycles per second, alpha is the gateway to meditation and provides a bridge between the conscious and the subconscious mind.
Slide 59-

BETA brainwaves are the fastest frequencies ranging from 14 cycles per second up to 38 cycles per second. Beta is your normal thinking state, your active external awareness and thought process. Without beta you would not be able to function in the outside world.
Slide 60-

THETA brainwaves are the subconscious mind. Ranging from about 4 cycles per second up to 8 cycles per second, theta is present in dreaming sleep and provides the experience of deep meditation when you meditate. Theta also contains the storehouse of creative inspiration and is where you often have your spiritual connection. Theta provides the peak in the peak experience
Slide 61-

The MEDITATION brainwave pattern is a combination of alpha and theta where theta provides the depth and profundity of the meditation experience – the subconscious inner space from which creativity, insight, and healing spring – and alpha provides the bridge, or the link, to the conscious thinking mind so that you can actually remember the contents of your meditation.
Slide 62-

DELTA brainwaves are your unconscious mind, the sleep state, ranging from about 4 cycles per second down to 0.5 cycles per second. But when present in combination with other waves in a waking state, Delta acts as a form of radar – seeking out information – reaching out to understand on the deepest unconscious level things that we can't understand through thought process. Delta provides intuition, empathetic attunement, and instinctual insight.
Slide 63-

AWAKENED MIND brainwave pattern It is a brainwave pattern shared by people in higher states of consciousness regardless of their philosophy, theology or meditation technique. This brainwave pattern can be found during “peak experience” and in all forms of creativity and high performance
Slide 64-

Permanent EEG changes 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 With chronic meditation, gamma wave activity(high level information processing) is found in many meditators
Slide 65-

Evoked potentials & meditation Meditation sometimes produces altered amplitudes, with practitioners seeming to demonstrate decreased amplitude & latency for sensory EPs & with mindfulness inducing a decrease in habituation
Slide 66-

In meditation the usual frameworks of time, space and other aspects of conscious content are absent, although the mind is not asleep Compared to quiet or slow-wave sleep, in which brain blood flow is reduced, meditation shows no reduction in total brain blood circulation or perfusion Regional maps of brain blood flow/perfusion differ among meditation, slow-wave sleep and wakefulness
Slide 67-

Neurobiology of Meditation Imaging, such as rCBF (regional Cerebral Blood Flow), real time MRI (Magnetic Resonance Imaging), MEG (magnetoencephalography), and improved EEG (electoencephalography) allow detailed studies in understanding the effects of meditation on neural behavior. SPECT study shows- Parietal area of the brain is responsible for giving us a sense of our orientation in space and time. By blocking all sensory and cognitive input into this area, meditation results in the sense of no space and no time.

fMRI changes during Meditation
Slide 76-

Results Significant signal increases were observed in the dorsolateral prefrontal and parietal cortices, thalamus, hippocampus/parahippocampus, temporal lobe, pregenual anterior cingulate cortex, striatum, and pre- and post-central gyri during meditation. This indicates that the practice of meditation activates neural structures involved in attention and control of the autonomic nervous system. Neuroreport. 2000 May 15;11(7):1581-5.

PET, SPECT & fMRI allow examination of changes in regional blood flow, metabolism or receptor (sites of neurochemical and drug actions) activation in the brain in response to various tasks Most types of meditation, which involve an initial focusing of attention, are associated with increased regional blood flow or glucose metabolism in the prefrontal and cingulate cortex, areas that are important in selection of a mental task fMRI changes during Meditation
Slide 79-

The frontal lobes, especially the prefrontal regions help to organize, prioritize, plan and focus attention During visualization regional blood flow increases in the “visual cortex” and visual association areas in the occipital lobes In contemplation of “self” the parietal lobes on both sides are activated

Thalamus & Hippocampus in meditation
Slide 85-

Thalamus is a relay station and filtering station for sensory information. Excitation of RN through PFC, decreases activation of PSPL & thereby decreases body awareness & also decreases input to visual centre (GABA) The studies point to prefrontal activation (predominantly right), transient hypofrontality, increased frontal lobe & decreased parietal lobe activity & also to a Deafferentation of the PSPL Functional Deafferentation means a decrease in distracting stimuli to visual cortex & PSPL, hence, increase focus This results in altered perception of self-experience
Slide 86-

Activity in Hippocampus is increased in connections with hypothalamus & autonomic nervous system Stimulation of Right amygdala causes stimulation of ventromedial hypothalamus & peripheral parasympathetic system, thereby causing subjective sensation of relaxation & more profound sense of quiescence

Slide 89-

Neurochemical Changes During Meditation Meditation increases Serotonin production, an important neurotransmitter and neuropeptide that influences mood and behavior in many ways. It can stimulate increased production of Acetylcholine, involved in memory mechanisms & attention Meditation has also been associated with increased melatonin availability
Slide 90-

Neurochemical changes during meditation During meditation, locus ceruleus activity decreases, thereby decreasing norepinephrine production Relatively greater activity of parasympathetic system causes decreased production of catecholamines, epinephrine & norepinephrine by adrenal medulla
Slide 91-

Neurochemical Changes During Meditation
Slide 92-

Meditation and the Autonomic Nervous System An increase in the skin resistance. Galvanic skin responses, showed that meditators recovered from stress more quickly than non-meditators. Decreased limbic arousal in the brain-reduces stress and increases autonomic stability to stress. Reduction in limbic arousal may explain how meditation strengthens and enhances the ability to cope with stress.
Slide 93-

Meditation and the Central Nervous System The practice of meditation decreases muscle reflex time. Accelerates neural conduction or augments the release of neurotransmitters, thereby decreasing synaptic time, resulting in a change in muscle firing threshold and pattern. By inhibiting the left cortical hemisphere, the sense of time and logic no longer dominate consciousness during meditation.Suppression of Ego faculty and later on Mind.
Slide 94-

The Plausible Hypothesis When meditation acts as a constant repetitive stimulus, certain permanent qualitative and quantitative changes develop in nervous system. Neurotransmitters and neuromodulators may stimulate growth of dormant neurons to develop a centre higher than neocortex- God module. This higher centre will exert inhibitory control over present neocortex and thereby over mind as a whole- thereby suppressing consciousness and all mental activities. Spiritual ascent is from the least evolved state of consciousness to near perfect state with which the mind itself will cease to be and there will remain only non-dual experience.
Slide 95-

Meditation and the Endocrine System Reduced blood levels of lactate, cortisol, and epinephrine. Reduces sympathetic adrenergic receptor sensitivity, producing a decreased response to stressful situations . Increased levels of gamma aminobutyric acid (GABA), melatonin and dehydroepiandrosterone sulfate. Meditation produces its anxiolytic effects by promoting GABA action in specific areas of the brain. Similar effects can be achieved by Reiki, Acupuncture.
Slide 96-

Meditation and Metabolism A wakeful state accompanied by decreased metabolism. Decreased breathing pattern, decreased heart rate, and decreased blood pressure. Blood flow to the kidneys and liver declined in the practitioners, with an increase in cardiac output. Decrease in the level of oxygen utilization and carbon dioxide elimination by muscles. The metabolic changes arise from a natural reduction in metabolic activity at the cellular level, not from a forced reduction of breathing. Longevity and delayed aging !
Slide 97-

Meditation & Neuroplasticity A recent MRI study showed that, “brain regions associated with attention, interoception & sensory processing like the PFC & right anterior insula were thicker in meditation practitioners” Meditation probably offsets age-related cortical thinning & thereby suggesting to promote Neuroplasticity
Slide 98-

Meditation and Psychology Practice of meditation improves cognitive task performance, increases mental concentration, and reduces susceptibility to stress. Both subjective and objective examinations reveal that meditation enhances perceptual sensitivity.
Slide 99-

Meditation and Psychology It improves the attitude & personality of a person Improved concentration and attention, allowing for greater productivity, problem-solving, creativity, learning ability and organization of memory. Enhanced self-image Less “catastrophic reaction” to stressful situations, e.g., in survivors of attempted suicide Better sociability, tolerance and compassion Improved mood, sleep & scores on self-actualization
Slide 100-

Attitude “ The Longer I live, the more I realize the impact of attitude on life. Attitude to me, is more important than facts. It is more important than the past, than education, successes, than what other people think or say or do. It is more important than appearance, giftedness or skill. It will make or break a company…….. a church…. a home. The remarkable thing is we have a choice every day regarding the attitude we will embrace for that day. We can not change our past..... we cannot change the fact that people will act in a certain way. We cannot change the inevitable. The only thing we can do is to play on the only string we have, and that is our attitude……. I am convinced that life is 10% what happens to me and 90% how I react to it. And so it is with you….. We are in charge of our Attitudes ”. - Charles Swindoll
Slide 101-

Neural correlates of anxiety Factors decreasing anxiety during meditation : Increased parasympathetic acitivity, GABAergic drive, serotonin, endorphins & AVP Decreased LC firing with decreased noradrenaline & decreased levels of stress hormone cortisol Depression Factors contributing antidepressant effect : Increase in serotonin, dopamine, melatonin, endorphin & AVP Decrease in CRH & cortisol
Slide 102-

Psychosis A variety of schizophrenic effects can be seen Meditation can induce psychotic states via mechanisms such as : Increased 5HT 2 receptor activation, leading to inhibition of LGB Increased DMT, causing hallucinogenic effects Increase in NAAG, having dissociative hallucinogenic effects Increase in dopamine affecting temporal lobe
Slide 103-

Implications for Psychiatry Complementary & alternative medicine ? Alternative to Hypnosis Low cost, with continuation for life Group dynamics & group practice Combination e.g. Mindfulness-Based Cognitive Behavior Therapy or Spiritually Augmented CBT Enhancing one’s psychological resources/holistic living/self actualization Meditative state changes may develop into traits Preventive Psychiatry
Slide 104-

Unresolved issues – New Frontiers Although we can understand how the various lobes and neurotransmitters function during meditation, how are these actions directed and by whom? What accounts for the actual awareness of the experience and of self and where are they perceived? How do we actually know that something is true and meaningful? What accounts for this conviction? The link with the Master Within and with Cosmic Consciousness has not been explained and cannot be approached from a neuroscience perspective
