neuroscience and meditation: take as good care of your brain as you do your body.

Its interesting that so many people I know are given to regular, if not daily, exercise routines, often putting in a couple of hours at the gym without a blink. If asked why, they invariably mention the numerous benefits of maintaining strength, flexibility and cardio performance for “it's the only body I've got.” Some explain that they love exercise in general, however many do it principally for the long term benefits, understanding the results are worth the time and effort it requires.

Yet so many admit they fail to practice meditation on a daily basis, even in the briefest of 5 - 10 minute intervals, explaining that “I have too much going on,” or “I can't sit still.” Some try to claim that their morning coffee and news reading, or their jogging is “meditative,” which would be like claiming “my television watching is how I exercise.” This is hardly a wise choice: increasing evidence via research shows that spending a life without training the mind is as detrimental to brain function as a life without exercise is to the body.

While activities that quiet the mind, such as hiking, swimming, painting, etc, are certainly soothing, they do not provide the same benefits as meditation, and the distinction is essential, as meditations based on focused attention (otherwise known as sustained concentration, wherein one steadily monitors the breath and body sensations without additional movement or thought) and open monitoring  (vipasanna meditation, which develops a non-reactive awareness that can attend to experience without identifying with the content) have clinically documented, significant long term neural benefits that soothing activities do not. Please note the citations below for a list of some of the hundreds of peer reviewed, clinical papers that document the importance role meditation plays in upgrading brain structure and performance.

Recent insights into the importance of meditation derive from the advent of new scanning technologies, notably fMRI. What they document is that our previous understanding of the brain, which was once considered to be somewhat set structure with hard-wired functions, was substantially incorrect. We know understand the brain to be continually flexible, with significant neuroplastic capabilities. It is, in other words, a uniquely malleable and self-editing organ, changing structure and function depending on the nature of our experience, how we focus attention, interpret the world and act. For example, a 1995 Harvard study documented that people who simply imagined playing the piano, without actually touching one, still rewired the somatosensory lobe in the same way that an actual piano players rewired their brains.

Lets review some of the significant developments over the last 15 years:

Long-term meditators increase the neural capacity of the hippocampus, cingulate, temporal gyrus, and insula, which are associated with the performance of memory, emotion-regulation, empathy, impulse control. In conjunction with exercise, meditation leads to reduction in vulnerability to alzheimer's disease.

Meditators, in as short a period of a few months, show continual and even activation in the cingulate, which focuses attention for sustained periods and, in conjunction with mirror neurons, allows for empathetic connection with others. Meditators invariably demonstrate superior ability to perform tasks that require uninterrupted attention.

There is also the benefit of increased levels of GABA, which lowers anxiety and improves one's disposition. In as little as two months, the left prefrontal region of the brain, associated with optimism, shows increased activity, even in the case of those who've previously suffered significant episodes of depression.

And of course there are the many health advantages to mediation which are well documented, such as the reduction of cortisol and stress, which in turn reduces high blood pressure, heart and digestive ailments, along with increasing the production of white blood cells. In short, meditation improves your brain function as significantly as exercise improves your health.

Given all the above, why would someone exercise without meditating? It's essentially choosing to take care of one's body without bothering to take care of one's brain. We do depend on both.

  1. Meditation used to be considered to be the realm of spiritualists, and a little "alternative" for the general population. There has been considerable research conducted to investigate the benefits of meditation, and the result is proof that meditation does impact the body and mind in several positive ways to help in the treatment of mental and physical conditions. Make daily meditation part of your life and enjoy the meditation benefits for yourself.

5 ways to resist obsessive thoughts (Vitakkasanthana)

The mind can be thought of as a committee
Our thoughts are present by many "voices," some skillful and unskillful
W there are some skillful voices in there, focusing on useful ideas, there are also the many voices in the "committee" that cause us suffering by advancing and encouraging useless, stress inducing ideas, plans, worries.

Some examples of unskillful, stress producing obsessions
—are dedictated to figuring out the worst possible outcomes (fear) of any situation
—fixate on unknowable future events, i.e. what will we experience later in life?
—try to figure out what other people are thinking about us
—compare ourselves with others, especially in material concerns
in general, the buddha broke these down the thoughts of craving, aversion and delusion.

How unskillful internal voices persuade us
some of these committee members try to get their way by
—most work by repeating the same thought over and over
—some split into thousands of variations that seem different, but are …

The Two Arrows of Suffering

“When hit with discomfort, the conventional reaction is to whine and regret, kick oneself, take it hard. So we feel two afflictions: 1) the inevitable, physical feelings [a first arrow the world blasts us with] and 2) the additional, mental reactions [the second arrow we shoot into ourself]. We may fail to note any relief or escape from uncomfortable feelings [the first arrow] other than to distract ourselves with sensual pleasure. So we cling to diversions, rather than observing what is actually present, the arising and passing of feelings.”
—The Buddha, The Arrow Sutta
This teaching is often summarized as “Pain is inevitable, but suffering is optional.” We have in life two forms of distress in life. The first arises from the unavoidable events that occur in life: the pains, insults, rejections, losses, separations, aging, sickness and on. Such events quickly give rise to inevitable, uncomfortable physical expressions, such as feelings that the wind knocked out of us, a hollowness in …

On Working with Thoughts

As many of us begin our meditation practice and spiritual journeys, we may start out with an agenda of silencing our thoughts, muting all our inner chatter, if only for a little peace and quiet. Naturally, such an attempt fails, as thoughts are an inevitable product of language and communication skills; indeed, they provide us with key tools that insure our survival, both individually and as a species. Without thoughts, our moment by moment experience would be overwhelming, confusing and impossible to learn from or share with others. And so thoughts are a necessary function of the mind, and its not surprising that they continue to jabber away, creating a distracting stream of content during those moments we've set a side for tranquility. This, of course, can lead to periods of frustration and disappointment for the new practitioner. Yet such a reaction is a needless detour on the path, as eliminating thoughts is not only impossible, its far removed from the goal of spiritual endea…
