Can neuroscience deliver on the promises presented by religion: freedom from suffering, violence, scarcity, and disease? Can neuroscience deliver us into a life where health, peace, and abundance reign?
The pledges of the world’s religions are so universal that it’s likely the longing for joy, inner peace, and well-being are hardwired into the human brain and have become a social instinct as powerful as the drive to procreate. The Bible, the Koran, and Buddhist and Hindu scriptures all teach that we can be delivered into a paradisiacal state, whether after death, at the end of time, following many reincarnations, or as a result of personal effort and merit. This state of liberation is called grace or Heaven by Christian religions, Paradise by Muslims, while Eastern traditions refer to it as awakening or enlightenment, using various terms such as samadhi, mukti, bodhi, satori, and nirvana.
But what if grace, samadhi, and enlightenment are really based in biological science? What if they are states of higher order and complexity created by programmable circuits in the brain? What if these circuits could make it possible to attain lifelong joy, inner peace, health, and well-being now, in this physical world, and not in some distant future or afterlife?
The Brain and Enlightenment
So with all this expanded brain power, what are we striving for? In the East, enlightenment has traditionally been associated with qualities such as generosity, compassion, peaceful acceptance, and an experience of oneness with all creation. In the fiercely individualistic West, our rather vague notion of enlightenment suggests an acceptance of the world as it is, or of discovering how we can change it for the better. Enlightenment for us also implies the common longing for novelty, exploration, and creativity, as personified by the explorers who venture into space.
If we take the Eastern qualities of enlightenment out of their religious context and place them in the realm of biological science, we find that they are attributes associated with the activation of the prefrontal cortex—the newest part of the human brain. On functional MRI scans, people who meditate regularly are shown to have developed brains that are wired differently than the brains of people who don’t meditate. They are better able to remain calm and stress-free, live in peace, and practice compassion. Curiously, their prefrontal cortex is the most active region in their brain during the states they describe as samadhi, or enlightenment. His Holiness the Dalai Lama describes enlightenment as “a state of freedom not only from the counterproductive emotions that drive the process of cyclic existence, but also from the predispositions established in the mind by those afflictive emotions.” The Dalai Lama is suggesting that enlightenment is a state of freedom from destructive emotions and from the limiting beliefs and repetitive behaviors created by these emotions.
Generosity and compassion arise only when the prefrontal cortex is able to throttle back the more prehistoric regions of the brain. Yet, for the prefrontal cortex to create functional pathways for joy and peace, the entire body and brain need to be healthy, fed with the proper nutrients, and trained with an inner discipline. We must heal our bodies and minds to empower the prefrontal cortex—the new brain, which is biologically programmable for bliss, extraordinary longevity, peace, and regeneration. For too long, this brain region has been kept offline, silenced by the same forces—scarcity, violence, and trauma—from which it promises to deliver us.
Once this new region in the brain is brought online, brain synergy is possible. Synergy means that the whole is greater than the sum of its parts. Engineers are familiar with how synergy operates. The tensile strength of stainless steel, for example, is nearly ten times greater than the tensile strength of iron, even though stainless steel is basically iron with a minute amount of carbon added to it. Both carbon and iron, by themselves, are brittle and flake easily. Yet, when combined, they make an extraordinarily strong material.
Brain synergy signifies a neurocomputer whose circuits are all turned on, tuned in, and operating collaboratively, each region attending to its functions—much as the heart attends to circulating blood while the lungs attend to respiration—creating a system that cannot be defined or even described by its component parts.
Reinforcing Toxic Neural Pathways and Subconscious Beliefs
Neural networks are a plastic, dynamic architecture, a constellation of neurons that light up momentarily to perform a specific task. This is why, as you mull over a particular thought (good or bad) or practice a particular activity (beneficial or detrimental), you reinforce the neural networks that correlate with those thoughts and skills. Each time a situation reminds you of an actual fearful or dangerous experience from your past and instinctual emotions are brought up, that specific neural network is reinforced. We strengthen the toxic emotions and neural networks in our limbic brain and begin to create subconscious beliefs about life. These beliefs drive our actions and reactions in all experiences.
PTSD, Emotional Stress, and Suffering
When we are exposed to severe trauma, we can develop a condition known as post-traumatic stress disorder (PTSD). Studies show that most people are likely to experience at least one life-threatening or violent event in their lifetime. The studies indicate that even if a person recovers from PTSD, he or she may continue to show mild symptoms. With PTSD many of life’s typical events are inappropriately routed through the limbic brain, where we relive, at least from an emotional perspective, the heart-wrenching trauma of events that may have occurred decades ago. PTSD is compounded because the limbic brain, primal as it is, can’t tell time and therefore can’t distinguish the difference between a painful event that occurred 20 years ago and the memory of that event triggered by a similar situation today. As an example, it was common for soldiers who returned from the Gulf War and the wars in Iraq and Afghanistan to become anxious or distressed when they heard fireworks or other sudden loud noises because their limbic brain did not understand it was no longer in the theater of war. Similarly, couples who go through a bitter divorce may recoil in shock when they hear each other’s voice many years after the marriage has ended.
But you do not have to be diagnosed with PTSD to have even seemingly benign events trigger intense emotional reactions.
This reinforcement can be done without our knowledge or when we are milking an emotional trauma for sympathy, whether from others or from ourselves. We might say, for example, “I don’t have to act maturely; after all, I had a terrible childhood.” By creating and repeating such a statement, we reinforce neural networks and emotional habits that are as distinct as the postural habits from an old whiplash injury that has affected the vertebra and muscles of the spine. These networks give rise to emotions, then beliefs that keep us favoring past pain, as well as behaviors that continually reinforce the trauma as well as the pity we have learned to so successfully milk.
While such a repetitive, circular pattern once served to ensure our survival, it has become toxic and has given rise to erroneous beliefs about the world and acquaintances, friends, and even family. Because beliefs can be unconscious, they may present themselves in ways that surprise us. We may start an intimate relationship that falls apart when we discover the person is not really who we thought he or she was, but the situation might actually be the product of our own unconscious belief that we will never find a partner. Likewise, we may have a terrific career opportunity that collapses because deep down we believe that we are not worthy.
Oddly enough, you can actually reinforce the toxic networks established by traumas by reacting with fear to a perceived threat. Unfortunately, whenever a situation is even faintly similar to some painful event from your past, a red flag goes up in your mammalian brain and you perceive it as a possible threat. This is because trauma is not what actually happened but how you stored it as a story in your mind. That is to say, you are impacted by what you believe occurred. And this story is kept alive below the threshold of consciousness, without your thinking or being aware.
