There is no wrong way to do a meditation—the right way is what feels right to you. (Location 206)
Last, if I know one thing for sure, it’s that you can do small things inside your mind that will lead to big changes in your brain and your experience of living. I’ve seen this happen again and again with people I’ve known as a psychologist or as a meditation teacher, and I’ve seen it in my own thoughts and feelings as well. You really can nudge your whole being in a better direction every day. (Location 209)
When your mind changes, your brain changes, too. In the saying from the work of the psychologist Donald Hebb: when neurons fire together, they wire together—mental activity actually creates new neural structures (Hebb 1949; LeDoux 2003). As a result, even fleeting thoughts and feelings can leave lasting marks on your brain, much like a spring shower can leave little trails on a hillside. (Location 216)
As you become a happier person, the left frontal region of your brain becomes more active (Davidson 2004). (Location 221)
What flows through your mind sculpts your brain. Thus, you can use your mind to change your brain for the better—which will benefit your whole being, and every other person whose life you touch. (Location 222)
Your brain is three pounds of tofu-like tissue containing 1.1 trillion cells, including 100 billion neurons. On average, each neuron receives about five thousand connections, called synapses, from other neurons (Linden 2007). (Location 228)
Each neural signal is a bit of information; your nervous system moves information around like your heart moves blood around. (Location 234)
even though it’s only 2 percent of the body’s weight, it uses 20– 25 percent of its oxygen and glucose (Lammert 2008). (Location 238)
it uses about the same amount of energy whether you’re deep asleep or thinking hard (Raichle and Gusnard 2002). (Location 239)
The number of possible combinations of 100 billion neurons firing or not is approximately 10 to the millionth power, or 1 followed by a million zeros, in principle; this is the number of possible states of your brain. To put this quantity in perspective, the number of atoms in the universe is estimated to be “only” about 10 to the eightieth power. (Location 240)
In the largest sense, your mind is made by your brain, body, natural world, and human culture—as well as by the mind itself (Thompson and Varela 2001). We’re simplifying things when we refer to the brain as the basis of the mind. (Location 246)

Like science, Buddhism encourages people to take nothing on faith alone and does not require a belief in God. It also has a detailed model of the mind that translates well to psychology and neurology. (Location 261)
Mental activity, whether conscious or unconscious, maps to neural activity, much like a picture of a sunset on your computer screen maps to a pattern of magnetic charges on your hard drive. (Location 285)
Of course, no one yet knows exactly how the brain makes the mind, or how—as Dan Siegel puts it—the mind uses the brain to make the mind. It’s sometimes said that the greatest remaining scientific questions are: What caused the Big Bang? What is the grand unified theory that integrates quantum mechanics and general relativity? And what is the relationship between the mind and the brain, especially regarding conscious experience? The last question is up there with the other two because it is as difficult to answer, and as important. (Location 289)
meanwhile, a reasonable working hypothesis is that the mind is what the brain does. (Location 296)
Me parece una posición súper simplista. El cerebro hace muchas cosas que tienen que ver solamente con el cuerpo, a menos que asumamos la posición de la Biología del Conocimiento, en donde todo sistema autopoiético es un sistema cognitivo. Ahora bien, no sé si esto calza con la noción de “mente” que el autor propone.

when experienced Tibetan practitioners go deep into meditation, they produce uncommonly powerful and pervasive gamma brainwaves of electrical activity, in which unusually large regions of neural real estate pulse in synchrony 30– 80 times a second (Lutz et al. 2004), integrating and unifying large territories of the mind. So, with a deep bow to the transcendental, we will stay within the frame of Western science and see what modern neuropsychology, informed by contemplative practice, offers in the way of effective methods for experiencing greater happiness, love, and wisdom. (Location 298)
Only we humans worry about the future, regret the past, and blame ourselves for the present. We get frustrated when we can’t have what we want, and disappointed when what we like ends. We suffer that we suffer. We get upset about being in pain, angry about dying, sad about waking up sad yet another day. This kind of suffering—which encompasses most of our unhappiness and dissatisfaction—is constructed by the brain. It is made up. Which is ironic, poignant—and supremely hopeful. (Location 315)
Virtue simply involves regulating your actions, words, and thoughts to create benefits rather than harms for yourself and others. (Location 327)
Mindfulness involves the skillful use of attention to both your inner and outer worlds. Since your brain learns mainly from what you attend to, mindfulness is the doorway to taking in good experiences and making them a part of yourself (Location 333)
Wisdom is applied common sense, which you acquire in two steps. First, you come to understand what hurts and what helps—in other words, the causes of suffering and the path to its end (the focus of chapters 2 and 3). Then, based on this understanding, you let go of those things that hurt and strengthen those that help (chapters 6 and 7). As a result, over time you’ll feel more connected with everything, more serene about how all things change and end, and more able to meet pleasure and pain without grasping after the one and struggling with the other. (Location 336)
Your brain regulates itself—and other bodily systems—through a combination of excitatory and inhibitory activity: green lights and red lights. It learns through forming new circuits and strengthening or weakening existing ones. (Location 343)
It’s a remarkable fact that the people who have gone the very deepest into the mind—the sages and saints of every religious tradition—all say essentially the same thing: your fundamental nature is pure, conscious, peaceful, radiant, loving, and wise, and it is joined in mysterious ways with the ultimate underpinnings of reality, by whatever name we give That.

It’s a general moral principle that the more power you have over someone, the greater your duty is to use that power benevolently.

To make any problem better, you need to understand its causes. That’s why all the great physicians, psychologists, and spiritual teachers have been master diagnosticians. For example, in his Four Noble Truths, the Buddha identified an ailment (suffering), diagnosed its cause (craving: a compelling sense of need for something), specified its cure (freedom from craving), and prescribed a treatment (the Eightfold Path).

Life began around 3.5 billion years ago. Multicelled creatures first appeared about 650 million years ago. (When you get a cold, remember that microbes had nearly a three-billion-year head-start!) By the time the earliest jellyfish arose about 600 million years ago, animals had grown complex enough that their sensory and motor systems needed to communicate with each other; thus the beginnings of neural tissue. As animals evolved, so did their nervous systems, which slowly developed a central headquarters in the form of a brain. (Location 429)
Nonetheless, the modern cortex has great influence over the rest of the brain, and it’s been shaped by evolutionary pressures to develop ever-improving abilities to parent, bond, communicate, cooperate, and love (Dunbar and Shultz 2007). (Location 440)
Over hundreds of millions of years of evolution, our ancestors developed three fundamental strategies for survival: Creating separations—in order to form boundaries between themselves and the world, and between one mental state and another Maintaining stability—in order to keep physical and mental systems in a healthy balance Approaching opportunities and avoiding threats—in order to gain things that promote offspring, and escape or resist things that don’t These strategies have been extraordinarily effective for survival. But Mother Nature doesn’t care how they feel. To motivate animals, including ourselves, to follow these strategies and pass on their genes, neural networks evolved to create pain and distress under certain conditions: when separations break down, stability is shaken, opportunities disappoint, and threats loom. Unfortunately, these conditions happen all the time, because: Everything is connected. Everything keeps changing. Opportunities routinely remain unfulfilled or lose their luster, and many threats are inescapable (e.g., aging and death) Let’s see how all this makes you suffer. (Location 447)
To live, an organism must metabolize: it must exchange matter and energy with its environment. Consequently, over the course of a year, many of the atoms in your body are replaced by new ones. The energy you use to get a drink of water comes from sunshine working its way up to you through the food chain—in a real sense, light lifts the cup to your lips. The apparent wall between your body and the world is more like a picket fence. (Location 462)
Language and culture enter and pattern your mind from the moment of birth (Han and Northoff 2008). Empathy and love naturally attune you to other people, so your mind moves into resonance with theirs (Siegel 2007). These flows of mental activity go both ways as you influence others. (Location 465)

Everything changes. That’s the universal nature of outer reality and inner experience. Therefore, there’s no end to disturbed equilibria as long as you live. But to help you survive, your brain keeps trying to stop the river, struggling to hold dynamic systems in place, to find fixed patterns in this variable world, and to construct permanent plans for changing conditions. (Location 538)
your brain is forever chasing after the moment that has just passed, trying to understand and control it. (Location 541)
In order to pass on their genes, our animal ancestors had to choose correctly many times a day whether to approach something or avoid it. Today, humans approach and avoid mental states as well as physical objects; for example, we pursue self-worth and push away shame. Nonetheless, for all its sophistication, human approaching and avoiding draws on much the same neural circuitry used by a monkey to look for bananas or a lizard to hide under a rock. (Location 545)
That aspect of experience—whether it is pleasant, unpleasant, or neutral—is called, in Buddhism, its feeling tone (or, in Western psychology, its hedonic tone). The feeling tone is produced mainly by your amygdala (LeDoux 1995) and then broadcast widely. It’s a simple but effective way to tell your brain as a whole what to do each moment: approach pleasant carrots, avoid unpleasant sticks, and move on from anything else. (Location 565)
Two major neural systems keep you chasing carrots. The first system is based on the neurotransmitter dopamine. Dopamine-releasing neurons become more active when you encounter things that are linked to rewards in the past—for (Location 586)
a part of your brain called the cingulate cortex (about the size of your finger, on the interior edge of each hemisphere) tracks whether the rewards you expected—fun with your friend, good food—actually arrive (Eisenberger and Lieberman 2004). If they do, dopamine levels stay steady. But if you’re disappointed—maybe your friend is in a bad mood—the cingulate sends out a signal that lowers dopamine levels. (Location 590)
The second system, based on several other neuromodulators, is the biochemical source of the pleasant feeling tones that come from the actual—and anticipated—carrots in life. When these “pleasure chemicals”—natural opioids (including endorphins), oxytocin, and norepinephrine—surge into your synapses, they strengthen the neural circuits that are active, making them more likely to fire together in the future. (Location 594)

When you’re awake and not doing anything in particular, the baseline resting state of your brain activates a “default network,” and one of its functions seems to be tracking your environment and body for possible threats (Raichle et al. 2001). This basic awareness is often accompanied by a background feeling of anxiety that keeps you vigilant. (Location 627)
The brain typically detects negative information faster than positive information. Take facial expressions, a primary signal of threat or opportunity for a social animal like us: fearful faces are perceived much more rapidly than happy or neutral ones, probably fast-tracked by the amygdala (Yang, Zald, and Blake 2007). In fact, even when researchers make fearful faces invisible to conscious awareness, the amygdala still lights up (Jiang and He 2006). The brain is drawn to bad news. (Location 635)
Negative events generally have more impact than positive ones. For example, it’s easy to acquire feelings of learned helplessness from a few failures, but hard to undo those feelings, even with many successes (Seligman 2006). (Location 642)
Even if you’ve unlearned a negative experience, it still leaves an indelible trace in your brain (Quirk, Repa, and LeDoux 1995). That residue lies waiting, ready to reactivate if you ever encounter a fear-provoking event like the previous one. (Location 648)
Negative experiences create vicious cycles by making you pessimistic, overreactive, and inclined to go negative yourself. (Location 651)
anxiety also makes it harder to bring attention inward for self-awareness or contemplative practice, since the brain keeps scanning to make sure there is no problem. (Location 654)
In Buddhism, it’s said that suffering is the result of craving expressed through the Three Poisons: greed, hatred, and delusion. (Location 659)
Only a small fraction of the inputs to your occipital lobe comes directly from the external world; the rest comes from internal memory stores and perceptual-processing modules (Raichle 2006). Your brain simulates the world—each of us lives in a virtual reality that’s close enough to the real thing that we don’t bump into the furniture. (Location 668)
Mini-movies keep us stuck by their simplistic view of the past and by their defining out of existence real possibilities for the future, such as new ways to reach out to others or dream big dreams. Their beliefs are the bars of an invisible cage, trapping you in a life that’s smaller than the one you could actually have. It’s like being a zoo animal that’s released into a large park—yet still crouches within the confines of its old pen. (Location 688)
First darts are unpleasant to be sure. But then we add our reactions to them. These reactions are “second darts”—the ones we throw ourselves. Most of our suffering comes from second darts. (Location 743)
In relationships, second darts create vicious cycles: your second-dart reactions trigger reactions from the other person, which set off more second darts from you, and so on. (Location 749)
Suffering cascades through your body via the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal axis (HPAA) of the endocrine (hormonal) system. (Location 763)
Social and emotional conditions can pack a wallop like physical ones since psychological pain draws on many of the same neural networks as physical pain (Eisenberger and Lieberman 2004); this is why getting rejected can feel as bad as a root canal. (Location 769)
The hypothalamus—the brain’s primary regulator of the endocrine system—prompts the pituitary gland to signal the adrenal glands to release the “stress hormones”epinephrine (adrenaline) and cortisol. (Location 775)
SNS/HPAA arousal stimulates the amygdala, which is hardwired to focus on negative information and react intensely to it. Consequently, feeling stressed sets you up for fear and anger. (Location 787)

most of us experience ongoing SNS/HPAA arousal. Even if your pot isn’t boiling over, just simmering along with second-dart activation is quite unhealthy. It continually shunts resources away from long-term projects—such as building a strong immune system or preserving a good mood—in favor of short-term crises. And this has lasting consequences. (Location 817)
In our evolutionary past, when most people died by forty or so, the short-term benefits of SNS/HPAA activation outweighed its long-term costs. But for people today who are interested in living well during their forties and beyond, the accumulating damage of an overheated life is a real concern. (Location 820)
frequent SNS/HPAA activation wears down the hippocampus, which is vital for forming explicit memories—clear records of what actually happened. (Location 834)
In less extreme situations, the one-two punch of a revved-up amygdala and a weakened hippocampus can lead to feeling a little upset a lot of the time without exactly knowing why. (Location 842)
Parasympathetic activation is the normal resting state of your body, brain, and mind. If your SNS were surgically disconnected, you’d stay alive (though you wouldn’t be very useful in an emergency). If your PNS were disconnected, however, you’d stop breathing and soon die. (Location 865)

As the saying goes, pain is inevitable but suffering is optional. If you can simply stay present with whatever is arising in awareness—whether it’s a first dart or a second one—without reacting further, then you will break the chain of suffering right there. Over time, through training and shaping your mind and brain, you can even change what arises, increasing what’s positive and decreasing what’s negative. (Location 881)

The longer that something is held in awareness and the more emotionally stimulating it is, the more neurons that fire and thus wire together, and the stronger the trace in memory (Lewis 2005). (Location 943)
When a memory is activated, a large-scale assembly of neurons and synapses forms an emergent pattern. If other things are in your mind at the same time—and particularly if they’re strongly pleasant or unpleasant—your amygdala and hippocampus will automatically associate them with that neural pattern (Pare, Collins, and Pelletier 2002). Then, when the memory leaves awareness, it will be reconsolidated in storage along with those other associations. (Location 969)

Recognize fear when it arises, observe the feeling of it in your body, watch it try to convince you that you should be alarmed, see it change and move on. Verbally describe to yourself what you’re feeling, to increase frontal lobe regulation of the limbic system (Hariri, Bookheimer, and Mazziotta 2000; Lieberman et al. 2007).

The diencephalon consists of the thalamus (the brain’s central switchboard for sensory information) and the hypothalamus, which directs your autonomic nervous system and influences your endocrine system through the pituitary gland. The hypothalamus regulates primal drive states (e.g., for water, food, sex) and primal emotions (e.g., terror, rage). (Location 1309)

The ancient circuitry of the brain is continually driving you to react one way or another—and equanimity is your circuit breaker. Equanimity breaks the chain of suffering by separating the feeling tones of experience from the machinery of craving, neutralizing your reactions to those feeling tones. (Location 1448)
With equanimity, situations have only characteristics, not demands. (Location 1454)
Equanimity is neither apathy nor indifference: you are warmly engaged with the world but not troubled by it. (Location 1454)
Be aware of sounds. Hear without being caught by what’s heard. Be aware of sensations. Sense without being caught by what’s sensed. Be aware of thoughts. Think without being caught by what’s thought. (Location 1467)
When you are equanimous, you don’t grasp after enjoyable experiences or push against disagreeable ones. Rather, you have a kind of space around experiences—a buffer between you and their feeling tones. This state of being is not based on standard prefrontal control of emotions, in which there is inhibition and direction of limbic activity. Instead, with equanimity, the limbic system can fire however it “wants.” The primary point of equanimity is not to reduce or channel that activation, but simply not to respond to it. This is very unusual behavior for the brain, which is designed by evolution to respond to limbic signals, particularly to pulses of pleasant and unpleasant feeling tones. (Location 1480)
Equanimity also involves remaining aware of the passing stream without letting any bit of it hook you. This entails anterior cingulate oversight, especially in the beginning stages of equanimity. As equanimity deepens, meditators report an effortless continuity of mindfulness, which presumably correlates with reduced ACC activity and self-organizing stability in the neural substrates of awareness. (Location 1492)
If you can break the link between feeling tones and craving—if you can be with the pleasant without chasing after it, with the unpleasant without resisting it, and with the neutral without ignoring it—then you have cut the chain of suffering, at least for a time. And that is an incredible blessing and freedom. (Location 1507)

In the dry language of evolutionary neuroscience, the “computational requirements” of selecting a good mate, sharing food, and keeping young alive required increased neural processing in mammals and birds (Dunbar and Shultz 2007). A squirrel or sparrow has to be smarter than a lizard or shark: better able to plan, communicate, cooperate, and negotiate. These are the exact skills that human couples discover are critical when they become parents, especially if they want to remain mates. (Location 1591)
the more sociable a primate species is—measured by things like breeding group size, number of grooming partners, and complexity of hierarchies—the bigger its cortex is compared to the rest of the brain (Dunbar and Shultz 2007; Sapolsky 2006). More-complex relationships require more-complex brains. (Location 1601)
Further, only the great apes—the most modern family of primates, which includes chimpanzees, gorillas, orangutans, and humans—have developed spindle cells, a remarkable type of neuron that supports advanced social capabilities (Allman et al. 2001; Nimchinsky et al. 1999). For example, great apes routinely console other members of their troop who are upset, although this type of behavior is rare among other primates (de Waal 2006). Like us, chimpanzees laugh and cry (Bard 2006). (Location 1603)
humans have many more spindle neurons than the other great apes; these create a kind of information superhighway running from the cingulate cortex and the insula—two regions that are crucial to social and emotional intelligence—to other parts of your brain (Allman et al. 2001). Although an adult chimpanzee is better than a two-year-old child at figuring out the physical world, that young human is already much smarter about relationships (Herrmann et al. 2007).

As the human brain evolved and grew larger, childhood grew longer (Coward 2008). Consequently, hominid bands had to evolve ways to keep their members connected for many years in order to sustain—in the African proverb—“the village it takes to raise a child” and thus pass on the band’s genes (Gibbons 2008). To accomplish this, the brain acquired powerful circuitry and neurochemistry to generate and maintain love and attachment. (Location 1653)
Distinct neural networks handle infatuation and long-term attachment. In its early stages, it’s natural for a romantic relationship to be dominated by intense, often volatile rewards that draw heavily on dopamine-based neural networks.
