  the diversity of species. When Isaac Newton (1643–1727) was

  asked about how he achieved his miraculous year of scientific

  and mathematical discoveries in 1666, he said he thought

  about nothing else for months at a time.

  selection dawned upon him. For Newton, the moment of

  insight is captured in the legend of the falling apple. For both

  these scientists, however, years of verification and testing had

  to follow. You can’t automatically trust an insight! Intuitions

  are frequently wrong.

  The Buddha certainly understood this process. The Sutta

  is a systematic training of the mind in preparation for deep

  thought, and for the flashes of insight that knit it all together.

  Sitting meditation is the first part of the first of the four foundations of mindfulness. The pursuit of insight, on the other

  hand, is the last part of the last of the four foundations.

  Another Pali text describes the process: “When his concen-

  trated mind is thus purified, bright, unblemished, malleable

  and steady, the monk devotes himself to investigating the Bud-

  dha’s dogma.”2 For example, in the Sutta: “The monk reflects

  on the Four Noble Truths that lead to nirvana. He understands

  by direct experience that: Life is suffering. The cause of suffer-

  ing is desire. Desire can be extinguished. The Eightfold Path of

  training extinguishes desire and leads to the end of suffering.”

  In other words, the Buddha is asking the monk to think in

  depth about the nature of life. The Buddha was a much more

  rational, nonmystical thinker than we give him credit for. In

  the texts, he repeatedly sets up his premises and argues his

  point from many different angles on concepts such as inter-

  dependent origination, the three characteristics of existence,

  the five aggregates, the six sense bases, and so on. It is fair to

  say that he regarded at least some degree of rational analysis

  as a crucial prerequisite to awakening.

  He still knew that thought alone was not enough. We can

  easily give our assent to a philosophy without a deep convic-

  tion that it is true. The Zen student knows that she is already

  enlightened, but she doesn’t quite believe it. We know that overeating is bad for us, but it doesn’t feel that way.

  Insights, however, are more potent and embodied. They

  go deep and carry a lot of weight. A bright idea or a break-

  through insight typically consolidates much of the rational

  analysis that has preceded it. It can irreversibly shift the

  thinker’s internal orientation to that issue, or it may simply

  be a big step along the way. Afterward, an insight can seem

  blindingly obvious, and easy to take as a given. (When

  Darwin’s colleague T. H. Huxley read Darwin’s foundational

  text on evolutionary theory in 1859, he exclaimed, “How

  extremely stupid not to have thought of it!”)

  Nonetheless, insights don’t have to be earth-shattering

  to qualify as such. We can regard an insight as any bright

  or potent idea that stands out from the usual run of mental

  chatter. They are the best part of your mental activity, so it is

  useful to be mindful of them. If you have an insight, I suggest

  you do the following:

  Stop your mental flow and hold the insight in mind. Hold

  it still and feel it. How true or deep does it seem to be? Is it

  going to hold up in different circumstances? Evaluate it and

  remember it. I frequently go for long philosophic walks. At

  the end I typically ask myself, “What were the best three or

  four ideas?” Other people might write them down. I deliber-

  ately lodge them in memory.

  Making big decisions is a lonely activity. The rule books

  usually don’t work, and simple nostrums are deceitful. As

  the journalist and satirist H. L. Mencken famously put it,

  “For every complex problem, there is an answer that is clear,

  simple, and wrong.” Aristotle regarded “practical wisdom”

  ( phronesis) as the ability to make good judgments in situations of uncertainty and inadequate information. He saw this

  as one of the fundamental skills of a mature adult.

  The Western term “enlightenment” means being able to

  think and determine the truth for yourself, based on the evi-

  dence, without reliance on political or religious authorities.

  The Sutta is a comprehensive mind-training discipline that

  aims at just this kind of self-reliance and mental vigor.

  The Buddha’s methods for improving our judgments

  are sophisticated and thorough. Meditation grounds us,

  and embodied thought is a type of cognition based on con-

  stant cross-referencing and feedback mechanisms using all

  parts of the body and brain. Over time, this can lead us out

  of childish, habitual, “confirmation bias” thinking toward a

  more intelligent and open-ended way of relating to the world.

  By clarifying our everyday decisions, mindfulness can help

  us become insightful, independent thinkers. It can make us

  enlightened, in the Western sense of the word.

  In this book we have now traversed from sitting medita-

  tion, which is the first part of the first foundation, to embodied thought and insight, which is the last part of the last

  foundation. This chapter marks the end of my analysis of

  the Sutta. The remaining four chapters discuss the modern

  understanding and applications of mindfulness.

  The Scientific Evidence

  Tens of thousands of studies on mindfulness and medita-

  tion have appeared since I started teaching in 1987. Many

  of these are of questionable quality, but the general drift is

  clear. Mindfulness seems to have positive effects for people

  suffering from anxiety, depression, pain, stress, insomnia, sub-

  stance abuse, and eating disorders. It helps with medical con-

  ditions such as cancer, hypertension, postoperative recovery,

  diabetes, irritable bowel syndrome, fibromyalgia, skin condi-

  tions, and poor immune function. It seems to work in all popu-

  lations, from children to the elderly, and across a great variety

  of occupations.

  Mindfulness has gone from strength to strength in recent

  years, but the research is still struggl
ing to describe how it

  achieves the results that it does. Let’s look at some of the most

  plausible hypotheses: namely, relaxation, enhanced body

  awareness, attention and thought control, and emotional reg-

  ulation.

  RELAXATION

  Most people would describe relaxation as a major reason for

  meditating. The most uncontroversial aspect of the research

  is that meditation enhances parasympathetic activity (the

  so-called relaxation response described on page 50). This alone

  is enough to explain its beneficial effects on heart rate, blood

  pressure, immune function, digestion, pain tolerance, and

  sleep quality. Learning to relax quickly and frequently during

  the day has the potential to permanently lower baseline levels

  of arousal and stress.

  So is relaxation part of the answer to alleviating mental

  distress? Not at all, according to some psychologists. From

  the start, the psychological literature has devalued the idea

  that relaxation could be useful as part of a treatment strat-

  egy. The pioneering writers constantly downplay its poten-

  tial as an agent of change and describe it as a pleasant side

  effect at best. They say this despite the fact that some degree

  of physical relaxation is virtually guaranteed in any medita-

  tion, while achieving a state of nonjudgmental acceptance is

  far less certain or measurable, even subjectively. I have yet

  to see any study that attempts to assess mindfulness in isola-

  tion from the confounding influence of relaxation. I’m sure it

  would be easy to design.

  Psychology has a long tradition of devaluing what hap-

  pens in the body in favor of purely mental dynamics. I won’t

  argue the obvious—that being able to consciously relax is cru-

  cial, and that doing so is both pleasant and good for you—but I

  suggest that you keep in mind the prejudice against the value

  of relaxation in the psychological literature. You can easily

  read dozens of scientific reports and not find a single reference to relaxation as a possible causative factor.

  ENHANCED BODY AWARENESS

  Meditation invariably enhances body awareness (and induces

  relaxation), whether that is the intention or not. This has many

  well-documented advantages. Enhanced body awareness leads

  to a conscious awareness of one’s emotions. It acts as an early

  warning device to pick up signals of overreactivity. It helps

  us to recognize our biological needs and limits long before

  crisis point. It seems to enhance our ability to accommodate

  unpleasant moods and sensations. It has the potential to

  increase empathy through the recognition of the body signals

  of others.

  Enhanced body awareness also alters the way that we think

  of ourselves. Our sense of self-identity operates through two

  distinct systems. The “narrative” system relies on language,

  memory, and a sense of purpose. This is “doing” mode: “This

  is me, my history, and what I do.” The “experiential” system

  relies on nonverbal, immediate interoception, and our sense

  of location in space. This is “being” mode: “This is how I feel

  in this moment.”

  Meditation strengthens this bodily sense of self at the

  expense of the narrative sense, and it consequently weak-

  ens excessive thought. If we feel grounded in our body, we

  are more able to see a thought as being “out there,” outside

  the body. Each time we do so we implicitly give more value to

  embodiment and less to mental chatter. Doing this thousands

  of times can train us to automate the response, and so reduce

  10/24/19 15:35

  the tendency toward rumination and self-referential verbal narratives.

  ATTENTION AND THOUGHT CONTROL

  Attention is the essential skill in meditation, and it consists of

  a variety of sub-skills. Learning to focus and sustain attention

  on the body is the antidote to the jumpy, anxious, scattered

  mind. Learning to switch attention away from a thought or

  behavior (“Let go and focus on the breath”) breaks the opposite

  tendency to fixate and ruminate. Learning to split attention

  appropriately increases mental efficiency and coping skills.

  Anchoring the mind in the body helps inhibit the second-

  ary elaborative processing of the thoughts, sensations, and

  emotions that arise while we meditate. Learning to “name” or

  “label” thoughts guarantees metacognitive awareness and is

  so beneficial that we find it in many therapies. The emphasis

  that mindfulness-based stress reduction places on devaluing

  thoughts indiscriminately undoubtedly helps many patients

  also. This ability to take a more detached stance in relation to

  one’s thoughts and feelings is called “decentering” or “defus-

  ing” or “reperceiving” in the psychological literature.

  These terms all suggest a general tendency to devalue

  thoughts per se. This is a common meditative strategy, but I

  prefer the Buddha’s approach. Sati-sampajjana is “the con-

  scious perception and evaluation” of something. Being con-

  scious, it evaluates a thought accurately, as it deserves, rather than automatically downgrading it. This is closer to the older

  cognitive behavioral therapy term “reappraisal” than to

  “defusing” or “decentering.” This may be the most important

  mindfulness skill in managing anxiety and depression.

  The research also suggests that even a very brief mindful-

  ness intervention can enhance our sense of self-control and

  discrimination. The reappraisal of any thought or impulse

  doesn’t even need to be conscious. A two-second “stop and

  look” pause is enough time for an implicit reappraisal.

  EMOTIONAL REGULATION

  Meditation lowers physiological arousal. This contributes to

  lower heart rate, blood pressure, and cortisol and adrenaline

  secretions while you are meditating. This may not change your

  underlying emotion, but it definitely turns down the volume.

  Meditation also weakens thought, thereby reducing the verbal

  amplification of any situation. It also requires that we sit still

  for several minutes, which means that we inevitably disarm our

  musculature and are less primed to act impulsively. This non-

  action is a profound signal from the body to the mind. It says,

  “No great urgency. No need to act right now.” It undermines

  the primary role of emotion, which is to initiate some kind of

  physical action.

  Psychologists speculate that poor emotional regulation is

  a primary driver of anxiety and depression. Conversely, they

  see a strong correlation betw
een self-reported mindfulness

  and good emotional control strategies. Mindfulness seems to

  help through mechanisms such as early intervention, reap-

  praisal, exposure, and the extinction of habitual responses.

  Paradoxically, trying to see things nonjudgmentally invari-

  ably results in a reevaluation of the object. Most commonly

  we down-regulate its emotional charge. We see it as less

  T H E S C I E N T I F I C E V I D E N C E | 2 8 1

  10/24/19 15:35

  important and therefore requiring little or no response. Some researchers now see positive reappraisal, not acceptance, as

  the key mediator of therapeutic change.

  The pioneering mindfulness writer John Teasdale explains

  how even a few seconds of conscious perception are bound to

  result in an automatic reappraisal. To be mindful holds an

  object in working memory for long enough to recontextual-

  ize it. Just a second or two of mindful attention to an emo-

  tional situation gives plenty of time for memories of similar

  past situations to arise. Since the mind automatically evalu-

  ates any new information and updates its assessments within

  milliseconds, being mindful of something will invariably

  modify the initial rule-of-thumb judgment about it.

  Good meditators gradually learn to automate a more tol-

  erant approach toward unpleasant stimuli, so they no longer

  need to cognitively control the process. Mindfulness thus

  contributes to our largely automatic reappraisals of moment-

  by-moment experience. Practiced regularly, this produces a

  stable, dispositional tendency to be mindful.

  Finally meditation enhances emotional control through

  brain mechanisms that are now well understood. Focusing

  and language are left-lateralized prefrontal cortex functions.

  Meditation thus results in front-back, left-right, “reason-

  emotion” inhibitions. Although both hemispheres always

  work together, focusing enhances left-hemisphere dominance

  over the right. The left hemisphere is analytical and rational

  and is associated with self-control and “positive” emotions.

  Conversely, the right hemisphere is more inclusive but is also

  more vulnerable to emotional confusion. Dampening the right

  hemisphere thus improves mood and a sense of control.
