“I’ve got the brain of a four-year-old. I’ll bet he was glad to be rid of it.” Groucho Marx
Even though yoga practice is far-ranging, not just all in your head, it is all in your head.
The brain is the center of the nervous system, 100 billion nerve cells protected by a skull and each nerve cell linked to almost 10,000 other cells. A real human brain lifted out of a jar in a pathology lab weighs about three pounds. Although often described as gray matter, it isn’t gray, but rather red, very soft and jelly-like.
The neural network of the brain is affected by everything that happens during its lifetime, for better or worse. Our genes and our environment impact every step. The brain’s lifelong development is activity-dependent. Every sensory, motor, and cognitive activity shapes the way neural circuits end up being wired.
Our experiences lead to cells that fire together, leading to cells that are wired together, leading to a mind that can count the stars in the sky and how many sprinkles are left at the bottom of an ice cream sundae at the same time.
Your brain on math is like it’s gone to the thinking gym. Your brain on money, on the other hand, is your brain shouting out greed is good, greed is good, greed is good! Your brain on meth is 100 MPH in a dirty sundress.
Brains in the thrall of sports are described in Your Brain On Sports as bubbling with “all the batshit craziness that courses through the sports ecosystem.” The kookiness includes fans leaning over balcony bleacher railings into mid-air trying to grab t-shirts shot out of a cannon.
Our neurons can misfire across synaptic gaps, raising Cain and spinning nonsense, from the NRA’s zany Cold Dead Hands to Climate Change Ain’t Happening. Only crazy people take themselves seriously.
Human being brains are always humming and roaring. They are our best friend and worst enemy. Everyone has to do the best they can with it. In the same way it is impacted by most things the brain is changed by most things, too, including yoga.
By some accounts yoga, from exercise on the mat to breath control to meditation, is a game-changer over and above many other things. Neuroplasticity is how the brain rewires itself through experience. The experience of yoga is plasticity itself, especially what goes on twisting and turning on the mat. The more anyone unrolls their mat is the more new neural pathways are made in the brain. It is a pattern that can reshape one’s brain and one’s life, too.
“Our life is the creation of our mind,” said Buddha.
Not only that, practicing yoga seems to make the brain bigger, especially the somatosensory cortex, where the mental map of our bodies is located, and the superior parietal cortex, which is the part of the brain that directs attention.
Who doesn’t want a bigger brain and a better GPS of themselves?
“We found that with more hours of practice per week, certain areas were enlarged,” said Chantal Villemure, one of a team at the National Center for Complementary and Alternative Medicine, which studied people practicing regularly. They presented their work, focused on MRI scans, to the Society for Neuroscience in 2013.
The health benefits of yoga exercise, from increased flexibility to stronger bones to relieving chronic pain, are well known. It even lowers the risk of heart disease, according to Harvard Health Publications. What is less well known is that it stimulates brain function, improving inhibitory control and working memory.
A University of Illinois study published in the ‘Journal of Physical Activity and Health’ found that cognitive reaction times and accuracy were better after hatha-style yoga practice than after other kinds of exercise.
“It appears that following yoga practice, the participants were better able to focus their mental resources, process information quickly, more accurately and also learn, hold and update pieces of information more effectively than after performing an aerobic exercise bout,” said Neha Gothe, who led the study.
The brain gets stronger after yoga exercise. Working out on the mat boosts the body’s production of B.D.N.F., a protein called ‘Miracle-Gro’ for the brain.
Downward doggers know that getting long feels awesome. Beyond flexibility they also know it brings to heel something in their brains. That something is stress, which yoga helps to counteract. Yoga boosts GABA levels in the brain, according to research at both the University of Utah and Boston University. The higher the GABA levels, the better and brighter you feel. The lower the levels, the darker the day gets. Yoga literally switches off some genes related to stress.
Hatha yoga nowadays is closely associated with physical practice. The word means forceful in Sanskrit. But, before yoga and physical culture became synonymous in the last hundred-or-so years, hatha meant all eight limbs of yoga. Yoga is an eight-limb union leading to the last limb, which is equilibrium. Two of them, pranayama, which is breath control, and dhyana, or meditation, may affect life and limb of the brain even more than physical practice.
“Yoga isn’t about the shape of your body, but the shape of your life,” said Aadil Pakhivavl, author of Fire of Love. Everybody wants to be in good shape, but getting in shape is about more than jump throughs and plank pose. Like Buddha said, life is what the mind makes it.
Breathing is as essential as it gets. The words chi, psyche, and spirit are all related to breath. In the Bible God breathed life into clay making Adam. In Your Atomic Self it is breath that connects us to all aerobic creatures in the world. Prana is the Sanskrit word for life energy or life force. Pranayama is regulating and controlling the breath.
Patanjali, the founder of yoga philosophy, believed the ultimate goal of it was not breathing anymore, in other words, no more inhales or exhales. It’s an idea that literally takes your breath away.
Whether it’s bellow’s breath, skull shining breath, or breath of fire, the many forms of pranayama are all designed to concentrate one’s energy and attention. When under the influence of pranayama our brains ramp up in alpha and beta activity, whose electrical impulses can be detected by EEG testing. These dissimilar brain activities, paradoxically, are related to increased awareness and increased relaxation.
“The immediate effect of Nadi Shuddhi Pranayama and Bhramari Pranayama compared with controls shows that these yogic practices are related with increased orderliness of brain functioning,” noted ‘Yoga for Academic Performance: A Brain Wave Coherence Analysis’ in the European Journal of Psychology and Educational Studies.
Meditation has long been known to generate measurable changes in the brain. Hundreds of studies have been conducted since the 1950s. They have largely confirmed that the new found benefits of meditation are the same as the centuries-old benefits, from reducing activity in the selfish centers of the brain to enhancing and enlarging the links of neural pathways.
In ‘Brain Gray Matter Changes Associated with Mindfulness Meditation in Older Adults’, published in the open journal Neuro in 2014, a “significant gray matter increase was identified within the precuneus” after a six-week test period. The precuneus is located near the back of the brain and is involved with aspects of consciousness and the self.
Meditation is about bringing awareness to the breath, slowing down into stillness, and going inward. It is the conscious action of getting to the unconscious crossroads of the something that isn’t there and the nothing that is. Immanuel Kant, the 18th century German philosopher, described art as purposive without a purpose. The same can be said about meditation. It is about nothing and everything and everything in between.
Meditation acts on the brain in many ways, from reducing anxiety and depression to improving concentration to helping keep brains tip top in older people. It leads to volume changes, actually changing the structure of the brain. A study at UCLA has demonstrated that people who meditate have more gray matter volume from one end of their pates to the other. “What we actually observed was a widespread effect of meditation that encompassed regions throughout the brain,” said study author Florian Kurth.
The act of meditation is the action of focusing one’s mind for a period of time, usually in silence, sometimes while chanting, as in Kirtan Kriya, to get grounded and become more self-aware.
Anybody can meditate, as long as they are willing to acknowledge that the mind has a mind of its own. All you have to do is sit down, or even go for a walk by yourself, and try to be quiet for a few minutes. Even though it doesn’t have to be a huge undertaking, it can have a huge impact. It’s not like climbing a mountain, but it does help cut most mountains down to molehills.
Even busy people too busy to meditate, who think they don’t have time to do nothing, are meditating nowadays, since it makes them more productive when they get back to being busy. “Half-an-hour’s meditation each day is essential, except when you are busy,” said Saint Francis de Sales more than four hundred years ago. “Then a full hour is needed.”
Today’s modern set calls it mindfulness meditation.
Back in the day it wasn’t even called meditation, which is a word dating from the 12th century, from the Latin word meditatum. It had more to do with attention and consciousness exploration. Meditation was closely aligned with dharana, or concentration, as in focusing one’s attention in continuous meditation.
Your brain on yoga is your brain diving into 5,000 years of the practice. It is also your brain being poked and prodded by the Harvard Medical School. Sat Bir Singh Khalsa, Ph.D, an Assistant Professor of Medicine at Harvard and a certified Kundalini Yoga instructor, has conducted clinical case studies on yoga for more than a decade. The results he has presented in research papers, articles, and books offer compelling evidence that getting on the mat boosts brainpower.
The brain might be a mush melon-sized lump of gray matter, but yoga lights it up like a rainbow. In the end, though, yoga isn’t a thinking man’s game. Anyone who spends too much time thinking about the practice never gets any of it done. While it is true that it’s a mind-body discipline, it’s not just exercise on a sticky mat, keeping us fit as fleas, nor is it just the latest contribution to positive thinking.
“Yoga is a way to freedom,” said Indra Devi.
We are more than our bodies and brains. The spirit is the third rail of yoga, so that the train becomes a body-mind-spirit practice. Albert Einstein believed that “spirit is manifest in the laws of the universe.” Like the electric action potential of neurons, the electric third rail of yoga is what supplies energy to the practice. When Buddha observed that our lives are what we think them to be, he meant thinking as a state of mind made up of cognition, words, and actions.
The humans of planet earth may be snared by force and their minds made small by propaganda, but the only constraints on the spirit are those we ourselves make. It’s great to have a good brain, but where the spirit lives is the good heart. We change our lives by changing what’s in our hearts. If there is a sweet spot of yoga, it is the heart, not the brain. It is the downtown of spirit and gateway to consciousness.
The heart is the ever-winding ever-adventurous ever-surprising yellow brick road to the incomprehensible. On the way to the Emerald City, no matter how big and better anyone’s brain gets, even when it makes a scarecrow’s leap from Groucho Marx to Albert Einstein, your brain on yoga is ultimately your brain emptying as the heart fills.
