We know that the human brain is a powerful organ, but many of us aren't aware of how much the mind is truly capable of -- and much more powerful it can become through deliberate training. By exercising the brain (yes, you can use repetition and habit as you do when you exercise the body), the mind can achieve things that may seem nearly impossible.


A multitude of studies have linked meditation with both physical and mental health benefits[1] , from reduced depression and anxiety to improved immune system functioning. And in the case of Buddhist monks who have devoted their lives to the practice of meditation, compassion and non-attachment, one line of research shows that the resulting changes in the brain from years of mindfulness practices can be staggering.


NYU researcher Zoran Josipovic, himself a Buddhist monk, has conducted research putting the brains of prominent Buddhist monks under fMRI machines to track the blood flow to their brains while meditating.


"Meditation research, particularly in the last 10 years or so, has shown to be very promising because it points to an ability of the brain to change and optimize in a way we didn't know previously was possible," Josipovic told the BBC in 2011[2] .


The monks who are part of Josipovic's research have accomplished extraordinary feats of mind, taking them beyond normal states of consciousness and effectively rewiring the brain. Here are some incredible findings from brain imaging studies on Buddhist monks that shed light on the astounding power of the human mind.


"What we found is that the longtime practitioners showed brain activation on a scale we have never seen before," neuroscientist and meditation researcher, Richard J. Davidson told the Washington Post[3] . "Their mental practice is having an effect on the brain in the same way golf or tennis practice will enhance performance."


You can change the brain's structure and functioning.

Neuroscientist Richard J. Davidson's groundbreaking research on Tibetan Buddhist monks at the University of Wisconsin-Madison has found that years of meditative practice can dramatically increase neuroplasticity -- the brain's ability to reorganize itself by creating new neural connections. These neural changes occur in response to experience, and allow the brain's neurons to change their activity in response to new situations or environment changes.


"The findings from studies in this unusual sample as well as related research efforts, suggest that, over the course of meditating for tens of thousands of hours, the long-term practitioners had actually altered the structure and function of their brains," Davidson wrote in IEEE Signal Processing Magazine in 2008[4] .


You can alter visual perception and attention.

In 2005, researchers at the University of Queensland in Australia and University of California at Berkeley[5] traveled to India to study 76 Tibetan Buddhist monks, in order to gain insight into how mental states can affect conscious visual experiences -- and how we might be able to gain more control over the regular fluctuations in our conscious state.


Their data indicated that years of meditation training can profoundly affect a phenomenon known as "perceptual rivalry," which takes place when two different images are presented to each eye -- the brain fluctuates, in a matter of seconds, in the dominant image that is perceived. It is thought to be related to brain mechanisms that underly attention and awareness. When the monks practiced meditating on a single object or thought, significant increases in the duration of perceptual dominance occurred. One monk was able to maintain constant visual perception for 723 seconds -- compared to the average of 2.6 seconds in non-meditative control subjects.


The researchers concluded[6] that the study highlights "the synergistic potential for further exchange between practitioners of meditation and neuroscience in the common goal of understanding consciousness."


You can expand your capacity for happiness.

Brain scans revealed that because of meditation, 66-year-old French monk Matthieu Ricard, an aide to the Dalai Lama, has the largest capacity for happiness ever recorded. University of Wisconsin researchers, led by Davidson, hooked up 256 sensors to his head, and found that Ricard had an unusually large propensity for happiness and reduced tendency toward negativity, due to neuroplasticity.


“It’s a wonderful area of research because it shows that meditation is not just blissing out under a mango tree but it completely changes your brain and therefore changes what you are,” Ricard told the New York Daily News[7] .


Davidson also found that when Ricard was meditating on compassion, his brain produced gamma waves "never reported before in the neuroscience literature."[8]


You can increase your empathy.

Research at Stanford University's Center for Compassion and Altruism Research and Education made some incredible findings last year. Neuroeconomist Brian Knutson hooked up several monks' brains to MRI scanners to examine their risk and reward systems. Ordinarily, the brain's nucleus accumbens experiences a dopamine rush when you experience something pleasant -- like having sex, eating a slice of chocolate cake, or finding a $20 bill in your pocket. But Knutson's research, still in the early stages, is showing that in Tibetan Buddhist monks, this area of the brain may be able to light up for altruistic reasons.


"There are many neuroscientists out there looking at mindfulness, but not a lot who are studying compassion," Knutson told the San Francisco Chronicle[9] . "The Buddhist view of the world can provide some potentially interesting information about the subcortical reward circuits involved in motivation."


Davidson's research on Ricard and other monks also found that meditation on compassion can produce powerful changes in the brain. When the monks were asked to meditate on "unconditional loving-kindness and compassion," their brains generated powerful gamma rays that may have indicated a compassionate state of mind, Wired reported in 2006[10] . This suggests, then, that empathy may be able to be cultivated by "exercising" the brain through loving-kindness meditation.


You can achieve a state of oneness -- literally.


happiness tips


Buddhist monks can achieve a harmony between themselves and the world around them by breaking the psychological wall of self/other, expressed as by particular changes in the neural networks of experienced meditation practitioners, the BBC reported[11] .


While a normal brain switches between the extrinsic network (which is used when people are focused on tasks outside themselves) and the intrinsic network, which involves self-reflection and emotion -- the networks rarely act together. But Josipovic found something startling in the brains of some monks and experienced meditators: They're able to keep both networks active at the same time during meditation, allowing them to feel a sense of "nonduality," or oneness.

  • Half Sun Salutation (Surya Namaskara)


    Sun Salutation sequences are traditionally performed as a way to awaken the body. "This is great to do upon rising, even before you have had your first cup of coffee," Bielkus says. To perform the sequence, stand up straight in <a href="http://www.yogajournal.com/poses/492" target="_blank">Mountain Pose</a> (<em>Tadasana</em>) with the feet together and arms at the side of the body with open palms. Sweep the arms up and extend them over the head on the inhale, then exhale and bow forward into a forward bend. On the inhale, lift the torso halfway up, place your hands at your shins and extend the spine. Fold forward again on the exhale. When you inhale, sweep back up and bring the palms together into prayer. Repeat this sequence three or four times. <a href="http://www.youtube.com/watch?v=0LPLwC4pRzk" target="_blank">Click here </a>for a video tutorial.




  • Camel Pose (Ustrasana)


    The gentle heart-opening stretch of the camel pose -- performed either with the hands on the lower back or reaching down to touch the heels -- can be highly invigorating for the entire body. "Camel is great because it's a total front-body opener," Bielkus says. "You have the front of the legs moving forward. ... The core is stretching and the torso is lengthening up. The chest is really opening and expanding so that the lungs can expand full of breath."




  • Warrior II Pose (Virabhadrasana II)


    "This pose combines both leg strengthening and mild back bending, bringing energy into the body," Bielkus says. "Just like the name suggests, this pose awakens the warrior within -- power and strength, but with ease." <a href="http://www.yogajournal.com/poses/495" target="_blank">Click here for basic Warrior II instructions</a>, and try adding what Bielkus calls the "breath of fire" for an extra energy boost. "A great way to rev up this posture is to add in breath of fire -- rapid belly breath, focusing on the exhalation," Bielkus says. "To start, take a deep breath in and then pump the navel in as you exhale. The inhale will take care of itself."




  • Triangle Pose (Utthita Trikonasana)


    After Warrior II, try going into a restorative Triangle Pose. Straighten the front knee and extend the arm forward and then down to the shin, the floor next to the leg, or a block. Reach the other arm up and turn to face the sky, breathing deeply for five breaths, Bielkus advises. Then, repeat on the other side. "This pose is about fully expanding not contracting," Bielkus says. "Focus less about stretching and more about expanding and bringing breath and energy to every cell, every skin pore, every fiber of your being."




  • Side Plank (Vasisthasana)


    For the whole body-strengthening Side Plank, start in a plank pose. Turn to the right side, stacking the feet on top of each other, and lifting the left hand. Breath deeply for five breaths before repeating on the other side. If you're looking to modify the pose, Bielkus suggests bringing either the bottom knee or the forearm down to the ground. "Yoga brings our mind to a oneness and a focused attention," Bielkus says, regarding the balancing poses. "The more that we're coming into a mental clarity or focus, the less energy we're expending on that stress. The cortisol levels can drop and then we feel a little more energized."




  • Chair Pose (Utkatasana)


    The dynamic Chair Pose is performed by standing with the feet together or hip-width apart, and bending the lower body down as if you were sitting on a chair. Raise the arms to the ears and raise the chest up to complete the pose. "This pose is literally translates from Sanskrit as 'powerful' pose," says Bielkus. "Sometimes in class, I refer to it as lighting bolt pose because [of] the amount of energy it creates in the body by using the big muscles of the legs and glutes while also creating a slight backbend, which awakens the spine."




  • Half-Moon Pose (Ardha Chandrasana)


    In addition to warding off stress and anxiety, the Half Moon Pose can be therapeutic for fatigue, <a href="http://www.yogajournal.com/poses/784" target="_blank">according to <em>Yoga Journal</em></a>. In a forward fold, bring the right hand about 10 inches in front of you and slightly to the right, extending the left leg up while the hips and torso open. Extend the left arm up and hold the pose for five breaths before repeating on the other side. "Any balancing poses are great for finding that inner balance," Bielkus says.




  • Bridge Pose (Setu Bandha Sarvangasana)


    "Back bends are all about unlocking the energy of the spine and nervous system," Bielkus says. Lying on your back, bend the knees and place your feet flat on the floor with arms by your sides. Lift the hips up high and interlace the hands together or leave the arms at the sides of the body. Breathe deeply for five breaths and repeat several times.




  • Locust Pose (Salabhasana)


    For this strengthening pose, lie on your belly with arms by your side and palms down. Then, gently lift the arms, legs, chest and head off the floor and breathe deeply for five breaths, trying to lift up higher with each breath. Repeat three or four times, being careful not to strain the neck. For more of a challenge, extend the arms in front of you, as pictured at left. "You're really stimulating the upper, middle and lower back, and the muscles of the hamstrings are engaging" Bielkus says. "You're using so many muscles in the body to lift yourself off the earth. The neurons are firing to make that all happen."




  • Right Nostril Breathing (Surya Bhedana)


    This energizing <em>pranayama</em> (breathing exercise) offers a counterpoint to the calming <a href="http://www.huffingtonpost.com/2013/06/30/yoga-for-sleep_n_3505226.html#slide=2629257" target="_blank">left nostril breath</a>. To perform the exercise, sit upright in a chair or on the floor in a comfortable cross-legged position, blocking the left nostril with the thumb and extending the fingers. Breathe long and deep, in and out of the right nostril for around five minutes, Bielkus advises. "The right nostril is associated with the energy of the sun," Bielkus says. "This breath is stimulating, invigorating and awakening."
