Numerous studies have proven the many physiological benefits of meditation, and the latest one comes from Harvard University.
An eight week study conducted by Harvard researchers at Massachusetts General Hospital (MGH) determined that meditation literally rebuilds the brain’s grey matter in just eight weeks. It’s the very first study to document that meditation produces changes in grey matter over time.
Study senior author Sara Lazar, of the MGH Psychiatric Neuroimaging Research Program and a Harvard Medical School Instructor in Psychology, explains:
Although the practice of meditation is associated with a sense of peacefulness and physical relaxation, practitioners have long claimed that meditation also provides cognitive and psychological benefits that persist throughout the day. This study demonstrates that changes in brain structure may underlie some of these reported improvements and that people are not just feeling better because they are spending time relaxing.
The study involved taking magnetic resonance images (MRI) from 16 study participants two weeks prior to the study. MRI images were also taken after the study was completed. Analysis of the images, “which focused on areas where meditation-associated differences were seen in earlier studies, found increased gray-matter density in the hippocampus, known to be important for learning and memory, and in structures associated with self-awareness, compassion, and introspection.”
For the study, participants engaged in meditation practices every day for approximately 30 minutes. These practices included focusing on audio recordings for guided meditation, and non-judgmental awareness of sensations, feelings, and state of mind.
According to Britta Holzel, first author of the paper and a research fellow at MGH and Giessen University in Germany:
It is fascinating to see the brain’s plasticity and that, by practicing meditation, we can play an active role in changing the brain and can increase our well-being and quality of life. Other studies in different patient populations have shown that meditation can make significant improvements in a variety of symptoms, and we are now investigating the underlying mechanisms in the brain that facilitate this change.
How to Meditate
A common misconception about meditation is that you have to sit a certain way or do something particular to see its benefits. But truly, all you have to do is place yourself in a position that is most comfortable to you. It could be sitting cross legged, lying down in a bed, sitting on a couch, etc.
Another common misconception about meditation is that you have to “try” to empty your mind. One important factor I enjoyed reading from the study mentioned above is that participants were engaged in “non-judgmental awareness of sensations, feelings and state of mind.” When meditating, you shouldn’t try to “empty” your mind. Instead, try to let your thoughts, feelings, and whatever emotions you are feeling at the time flow. Don’t judge them, don’t attach to them, just let them come and go and be at peace with it.
I also believe that meditation is a state of being more than anything else. One does not have to sit down for half an hour and “meditate,” so to speak, in order to reap the benefits of it, or to be engaged in the practice itself. One can be engaged in meditation while they are on a walk, for example, or right before they fall sleep. Throughout the day, one can resist judging their thoughts, letting them flow until they are no more, or just be in a constant state of peace and self awareness. Contrary to popular belief, there is more than one way to meditate.
“You will have to understand one of the most fundamental things about meditation: that no technique leads to meditation. The old so-called techniques and the new scientific biofeedback techniques are the same as far as meditation is concerned. Meditation is not a byproduct of any technique. Meditation happens beyond mind. No technique can go beyond mind.”
