Ego is the connecting link between consciousness "the soul" and the identity of consciousness as the living (human) manifestation. How it is programmed is how it filters information between the two points. What it is capable of is limited only by what is believed as "real" and "illusion".

CHAPTER 2
NEW EVIDENCE
The Science of Brainhacking
Brainhacking works. By following a few simple instructions, you can, over time, change the nature of your brain to make it more resilient, more resistant to aging, and more capable of happiness, compassion, and clarity. The data is in, and it matters.
It matters, in fact, in two distinct ways. First, as this hard data filters through the U.S. healthcare industry, the educational System, the military, and the corporate world, to name just a few examples, it will become clear that mindfulness is among the most cost-effective methods ever for reducing hospital stays, advancing educational opportunity, and improving the functioning of organizations. This will be a game-changer. Second, the science changes how the dharma is even to be understood. This hard data is the opposite of soft spatiality. Meditation and mindfulness are tools, not a set of spiritual exercises whose merit depends on faith or some unknown forces. This is why I've used the word "technology" in describing the work of meditation, why Kenneth Folk calls it a form of "contemplative Fitness," and why I like the term "brainhacking". We're not referring here to actual, physical technologies like electrodes or vibrating plants or special sounds that put you into an altered state (although all of these exist). Rather, when I say "technology” I'm thinking how meditation and mindfulness are tools—processes that lead predictable results.
When people go to the gym, for example, they know pretty much what's going to happen, and how it's going to happen. Lifting weights causes muscles to stretch and even tear a little, causing lactic acid to build up, causing the muscles to rebuild themselves bigger and with more capacity than they had before. It's a physical process, and while trainers will debate the best methods until end of time, the basic operation is clearly understood. Meditation is similar. If you do the work, predictable changes in the mind (experience) and the brain (neuroscience) tend to result, in a fairly reliable way. This, in a sense, is the very opposite of spirituality—and it’s certainly not religion either. It's more like working out: Each time I come back to the breath, I'm strengthening very specific neural networks. This perspective has already informed how millions of people around the world are enhancing their mental and emotional capacities. And the revolution has only just begun.
The Monk in the Machine
"Contemplative neuroscience”. The term, and the field, didn’t exist twenty years ago, but now it is changing how we understand the brain and how to optimize its function. In 1980, not a single article was published in a scientific journal on the effects of meditation and mindfulness. In 1990, there were five. In 2000, twenty-one. But in 2010, there were 353; in 2011, 397; and in 2012, there were 526.2 Scientists have measured mindfulness's capacity to reduce stress, improve immune response, and so on; they have detected activation in different parts of the brain during meditation; and they’ve conducted long-term studies of experienced meditators, beginning meditators, and even children practicing mindfulness in hospital settings.3
In the last ten years, there's been a small raft of books explaining how meditation changes the brain and specifically increases its capacities for calm, compassion, generosity, and other virtues. Richard Davidson's The Emotional Life of Your Brain, Norman Dodge’s popular The Brain That Changes Itself , Rick Hanson's books including Buddha’s Brain and Meditations to Change Your Brain, Allan Wallace's Buddhism and Science: Breaking New Ground, Jeffrey Schwartz and Sharon Begley's The Mind and the Brain: Neuroplasti4 the Power of Mental Force, Daniel Siegel's The Mindful Brain, John Arden's Rewire Your Brain, and a dozen other such volumes describe, often in usefully meticulous detail, the ways in which neuroscientists have been able to measure the increases in brain activity n capacity in areas correlated with positive mental capabilities. Fortunately for both of us, we will not be reviewing all of these findings here. But I do want to focus on two general types: clinical/ behavioral and neurological. The first data set tells us what meditation does clinically, as measured by changes in behavior and mental health, the second set tells us how this happens in the brain.
One way in which studies have obtained the first type of data is to measure the effects of MBSR, the meditation and relaxation regimen that we discussed in the last chapter. Its effects have been measured by hundreds of research papers, more than forty projects at the national Institutes of Health,4 and by mainstream scientists at mainstream universities, including UCLA's Mindful Awareness Research Center, the University of Wisconsin's Center for the Investigation of Healthy Minds, and labs at Yale, Brown, Duke, and elsewhere. In one long-term study, for example, Jon Kabat-Zinn showed that 25 chronic pain patients who were taught MBSR reported improvements in symptoms and mood, as well as fewer hospital visits.5 (Interesting, the study showed no diminishment of pain intensity; in other words, the patients were experiencing the same degree of pain but coping with it better.) MBSR has been shown to reduce stress and anxiety by a number of measures: heart rate, cortisol levels, a shift in the left frontal activity of the brain, and course people reporting that they're not as stressed out as they used to be.6 More broadly, here are some of the things mindfulness is been shown to do:
• Cut the relapse rate in half for patients suffering from depression7
• Reduce loneliness among elderly people8
• Quadruple the speed of healing from psoriasis9
• Improve overall immune function10
• Lower the rate of relapse among recovering addicts11
• Improve attention, planning, and organizational skills among grade-school students12
• Lower stress among breast cancer survivors13
• Reduce the side effects of organ-transplant surgery14
• Reduce ADHD symptoms in children15
• Relieve anxiety and depression in people with social anxiety disorder16
• Help patients manage chronic pain17
• Improve memory in older adults, with attendant neural correlates (increased symmetry in the thalamus) measured by brain scans18
• Counter age-related declines in brain function and fluid intelligence (problem-solving, reasoning, and similar abilities)19
This really is just the tip of the iceberg. The entire remainder this book could be taken up with findings of this nature and the rate of study continues to increase. Perhaps most remarkably, any of these benefits begin accruing after short periods of time. In one study, just two weeks of meditating just a few minutes each day was shown to be more effective than simple relaxation at lowering stress responses.20 Even beginning mindfulness practitioners reported subjective improvements in awareness and nonreactivity21 Such findings have potentially huge societal and financial impact; imagine the value of a corporation improving its aging executives' mental abilities, or the impact of arresting memory loss in older adults. It’s no wonder some of the hype about this new science is so breathless, why Silicon Valley types gather at conferences like Wisdom 2.0 to talk about how to adapt mindfulness to the workplace and market it to consumers everywhere. (More on that in Chapter Seven.) Meditation may be the ultimate disruptive technology.
Until very recently, however, it was not known how these changes in resilience and behavior came about. That has begun to change with the advent of contemplative neuroscience, and, in particular, our (only) fifteen-year-old understanding of neuroplasticity22 . Neuroplasticity is the brain's ability to change itself, to paraphrase Norman Doidge,23 in response to learning, experience, and other stimuli. Scientists used to think that brain development more or less ended at adolescence. Now we know that isn't true, and that, just like building muscles, you can build capacity in various regions of the brain throughout your life. This is true when you meditate, when you learn a new skill, and when you habituate yourself to various stimuli. A favorite example of neuroscientists is the study done on the brains of London taxi drivers, which found that the regions of the brain associated with visual memory (essential for memorizing London's rabbit warren of streets) were significantly more developed among the taxi drivers than among the general public. Neuroplasticity can also have negative consequences: one example Doidge discusses is how the overuse of pornography rewires the brain's pleasure centers, causing it to need ever-more-exotic visual stimuli to generate the responses associated with arousal.24 As the saying goes (possibly coined by Doidge himself), neurons that fire together, wire together—for better or for worse.25
The myriad details of how Neuroplasticity works in different contexts are quite complicated; it’s not as simple as building up one part of the brain when you meditate, since various regions of the brain are involved in most activities.26 They are also exhaustively discussed in some of the volumes I listed above, and as a non-scientist I'm not inclined to reinvent that particular wheel here. Instead, I want to bullet-list out some of the neurological changes that have been found to result from extended meditation, to give a sense of what we are beginning to understand:
• While meditating, meditators show enhanced frontal brain activity, enhanced gamma power in the occipital cortex, and decreased frontal reactivity to distracting and unexpected stimuli.27
• When MBSR students focus on body parts, alpha waves increase in the areas of the brain corresponding to the areas of the body under attention.
• When Richard Davidson measured Tibetan monks doing compassion meditation, he measured gamma activity - "the high-frequency brain waves that underlie higher mental activity such as consciousness"—greater than ever recorded in scientific literature.28
• An fMRI scan on the same meditators showed heightened activity in the insula, also associated with emotion and consciousness.29
• When Davidson tested meditators after a three-month retreat in 2005, he found their "attentional blink"—the brief gap all of us experience when we try to pay attention—to be much less than that of ordinary people.30
• Long-term meditators were shown to require less brain activity to perform cognitive tasks than non-meditators.31
• Mindfulness revealed activation in the anterior cingulated cortex (ACC), a "crucial node in the attentional network”32
• Dr. Eileen Luders, in a series of studies, measured regional volumes in different parts of the brain, gray matter concentration, white matter fiber integrity, callosal thickness, hippocampal distances, and cortical gyrification—and found that meditators exceeded control subjects in every one of these measures.34
• One example in Luders' study: long term meditators' fractional anisotropy (FA) —basically, the degree of connectivity in the brain's white matter fibers—was higher than control groups' in twenty fiber tracks. This is important because FA decreases with age, causing (scientists think) many of the symptoms of senility. Yet Luders found that FA decreased much less for long-term meditators than for other people.35
• Long-term meditation increases cortical thickness in parts of the brain36 and increases gray matter volume.37 These long-term results Davidson analogizes to "measuring the strength of the biceps of a bodybuilder when he's not doing curls'38
As before, these neuroscientific data are but a sliver of a large and growing scientific literature. Let me try to put this into a lay person's terms, focusing on how one region of the brain, the amygdala, interacts with others. (Interestingly, this description of the amygdala has been taught to high-schoolers as part of the MindUP curriculum, funded by Goldie Hawn's charitable foundation.39) The amygdala is the part of the so-called "reptilian" brain, the brainstem, that reacts quickly to threats, that has saved your life dozens of times by instinctively getting you out of a dangerous situation, and by firing off quick "fight or flight" responses. We all depend on our amygdalas, but if we're controlled by them, we're apt to be their marionettes, jumping when they say jump, fearing whenever they perceive a threat. (Indeed, you can see how the amygdale can be manipulated during any political campaign.) Animalistic impulses to anger, desire, fear – this is what the amygdale produces. How does meditation affect the amygdala? Davidson found that after two weeks of training in loving kindness practice, there was less activity in the amygdale when subjects were shown distressing images.41 In other words, they didn't react as strongly. Meanwhile, other parts of the brain moderate the impulses of the amygdala are strengthened by meditation, including the medial prefrontal cortex, adjacent precuneus, and other areas necessary for self-regulation. For example, the prefrontal cortex is associated with body regulation, communication, emotional balance, response flexibility, empathy, insight, self-knowing awareness, and fear modulation—the last of which it accomplishes by releasing an inhibitory neurotransmitter (GABA) that actually counters the impulses of the amygdala.41 In a study of MBSR practitioners, left side prefrontal cortex activation tripled after four months of practice.42
In other words, activity in the reactive mind—the impulsive, want-it-don't-want-it, have-sex-with-it-or-kill-it parts of the brain- decreases with meditation, while activity in the reflective, regulatory, mind increases. (By way of comparison, it's generally understood that when limbic activity in the amygdala and hippocampus dominates prefrontal activity; the result is a psychopathology.) Anecdotally, this model does seem to correlate with the experiences many meditators, including this one, have had. A stimulus is present that normally causes aversion: a difficult family member, a perceived threat. Yet rather than immediately react, meditators sometimes report a "spaciousness" around the negative stimulus. I want to lash out, but ok I don't have to. It seems to me that the physical processes these neuroscientists are describing do correlate to the mental-experiential processes I experience. There's no way to know, as yet, exactly what physical processes accompany or cause these mental events, and certainly no way to know that through introspection. But “feeling fear but not acting on it" is a physical, chemical process, even if it is experienced subjectively as purely mental in nature. As Freud is reported to have said, "all our provisional ideas in psychology will presumably someday be based on organic substructure.”43
Why does all this matter? First, as Richie (as everyone calls Professor Davidson) said to me,
The neuroscientific work provides a foundation that has enabled the incorporation of these practices in a wider swath of our culture. I see the work as creating openings in certain segments of healthcare and education that might not otherwise have been as receptive, by providing mechanisms, in modern scientific language, through which these dharma practices may actually be producing various effects. I think this has been extraordinarily helpful in these domains.
The science legitimizes the expansion of the dharma. It supports an overall view of the dharma not as religion, not as spirituality, but as a technology for upgrading the mind to be more resilient - "brainhacking,” if you like. Appearances notwithstanding, it is helpful to regard the zendo more like a gym than like a church or a synagogue. In addition to its efficacy in talking about the dharma with others, I have found this outlook to be profoundly liberating, and will discuss it in more detail in just a moment.
Now, as with all such findings, there remains a significant gap between the scientific data—couched, as it usually is, in cautious terms—and its inevitable oversimplifications. Davidson again:
There's a lot we don't know. People often think that we know that meditation has certain kinds of health impacts, but I think we know preciously little about that, and even less about how it may have those impacts. We know very little about the most effective ways of teaching these practices in a secular way... . We know almost nothing about what the optimal dosage, if you will, might be, and how that may vary across different kinds of individuals . . . we know a lot less in those domains than we think we know.
Even within the bounds of contemplative neuroscience, several methodological challenges remain: finding adequate control and comparison groups (there aren’t so many people with 10,000 hours of meditation experience out there – my own number is around 3,000.

Unfortunately, Fauer himself overgeneralizes as well, describing mindfulness as "usually regarded as a rudimentary practice,” for example. This may be true of Vajrayana practitioners, but the Buddha described it as “the direct path to realization” – hardly rudimentary. Faure also alleges that the neuroscientific studies are in the service of a dark, pharmaceutical conspiracy. Since I am sure Faure knows as many of the researchers personally as I do, I am not sure how he can possibly make that charge. The ones I have met are sincerely motivated by curiosity and an optimism that the dharma can reduce suffering. If they wanted to make money from drug companies, they could have sold out long ago. Unfortunately, must of Faure’s article is a rant by an Orthodox Buddhist and Buddhist scholar who is unhappy that dharma has evolved beyond its traditional containers and contexts.
