Neuroscience and the ‘Sanskrit Effect’

Neuroscience and the ‘Sanskrit Effect’
Science Proves the Power of Chanting

Many of us have heard the Gyuto Monks of Tibet. With their extraordinary chanting and the low throaty drone of ancient sacred texts, they have kept audiences in the West spellbound with their long, careful and accurate recitations of potent Tibetan Buddhist texts. Sitting in their presence, you feel clarity and a potent spiritual transference of energy and healing. The Buddhist tradition stems from India and the sacred language of Sanskrit. While Tibetan Buddhists have a rich chanting tradition, in India, this age-old tradition goes back even further.

Sanskrit scholars in India learn to chant ancient texts from a tender age. They chant simple mantras, Sanskrit poetry, and prose, along with memorising and chanting the most ancient Sanskrit texts, including the Shukla Yajurveda, which takes six hours to chant. While those listening to these chantings receive the gift of the sacred texts they are sharing with us, the chanting of long texts does, in fact, have an amazing effect on the brain.

Neuroscience shows how rigorous memorising can help the brain. The term the ‘Sanskrit Effect’ was coined by neuroscientist James Hartzell, who studied 21 professionally qualified Sanskrit pandits. He discovered that memorising Vedic mantras increases the size of brain regions associated with cognitive function, including short and long-term memory. This finding corroborates the beliefs of the Indian tradition which holds that memorising and reciting mantras enhances memory and thinking.

An Unexpected Discovery…

Dr. Hartzell, a Sanskrit devotee and postdoctoral researcher at Spain’s Basque Centre on Cognition, Brain and Language, spent many years studying and translating Sanskrit and became fascinated by its impact on the brain.

I noticed that the more Sanskrit I studied and translated, the better my verbal memory seemed to become. Fellow students and teachers often remarked on my ability to exactly repeat lecturers’ own sentences when asking them questions in class. Other translators of Sanskrit told me of similar cognitive shifts.

India’s Vedic Sanskrit pandits train for years to orally memorise and exactly recite 3,000-year old oral texts ranging from 40,000 to over 100,000 words. We wanted to find out how such intense verbal memory training affects the physical structure of their brains.

Dr. Hartzell’s research is the first study to examine the brains of Sanskrit scholars. Using structural Magnetic Resonance Imaging (MRI) at India’s National Brain Research Centre, they scanned the brains of 21 Sanskrit pandits and 21 control subjects.

What we discovered from the structural MRI scanning was remarkable. Numerous regions in the brains of the pandits were dramatically larger than those of controls, with over 10 percent more grey matter across both cerebral hemispheres, and substantial increases in cortical thickness. Although the exact cellular underpinnings of grey matter and cortical thickness measures are still under investigation, increases in these metrics consistently correlate with enhanced cognitive function.

He reports that the right hippocampus of the scholars, a region that plays a vital role in short and long-term memory, and is specialised for patterns, such as sound, spatial and visual patterns, had more grey matter than the brains of the control subjects. The right temporal cortex, associated with speech prosody and voice identity, was also substantially thicker.

Past Studies

Dr. Hartzell is not sure whether the effect relates particularly to the Sanskrit language and plans to conduct further research. The power of sound and chanting is becoming widely documented, and even short chants have an energising and healing effect on the body and mind of those who are chanting sacred mantras or verses. Interestingly, fifty years ago, a French scientist noted that Christian monks who chanted the Gregorian Chants have exceptional memories.

In 1967, Alfred Tomatis, a French physician, psychologist, and ear specialist, studied the effect of chanting on Benedictine monks who had been part of a tradition with a strict schedule of daily chanting of up to eight hours a day. When a new Abbott changed this schedule, cutting out the chanting, the monks became tired and lethargic, even though they were getting extra sleep. In fact, the more sleep they got, the more tired they were. Alfred Tomatis believed that the chanting was energising their brains and bodies, so he reintroduced the chanting and the monks were soon full of energy again.

Dr. Hartzell’s recent study raises the question of whether this kind of memorisation of ancient texts could be helpful in reducing the devastating illness of Alzheimer’s and other memory affecting diseases. Apparently, Ayurvedic doctors from India suggest it is the case and future studies will be conducted, along with more research into Sanskrit.

While we all know the benefits of mindfulness and meditation practices, the findings of Dr. Hartzell are truly dramatic. In a world of shrinking attention spans, where we are flooded with information daily, and children display a range of attention deficit disorders, ancient Indian wisdom has much to teach the West. Even introducing small amounts of chanting and recitation could have an amazing effect on all of our brains.

Thanks for this. As a yoga monk, I’ve been teaching and using kiirtan chanting with sanskrti mantras for more than 40 years. I’ve been looking for really solid, peer reviewed research on kirtan in particular, but it is very hard to find.
This article does not make it clear how these results are significantly different from studies of any kind of intense memorization practice, for example, the well known study of London taxi drivers (pre GPS) who study maps of London intensely for up to 4 years to get their licence. This was one of the first studies using fMRI scanning to demonstrate neuroplasticity and neural pathways at work.
So, while I’m personally quite convinced of the special power of sanskrta chanting, I’m still looking for really sound empirical validation of the practice. I’d love to know if anyone has found some of these studies. Needs to be backed by a reputable, relatively objective institution such as a university.

If this language is so very powerful, then why did it die ?

Dr Herbert Benson says, having your eyes closed and reciting ‘Monkey, monkey or Donkey, donkey’ for 20 minutes would yield a lot of benefits with regard to physical and psychological well-being.

In what scientific ways, Sanskrit is different ?

Sanskrit language has no actual origins it’s a doctored language created by Jewish people who used translators to extract information from an older language within India but unfortunately the truth is hidden in India.

Absolutely,chanting of Sanskrit mantras definitely activate the brain and give a lot of stamina to sit still for a longer time as compared to other subjects .It increases concentration .Mere chanting without understanding the meaning has a wonderful effect on the brain,and chanting oh mantras with understanding of each and every word definitely increases enthusiasm.Sanskrit chanting ,firstly should be inculcated in our school curriculum right from Kindergarten instead of English nursery rhymes.Later Sanskrit as a subject can be incorporated.Hope this will happen soon in our country.Schools in some countries have already adopted this method of imparting Sanskrit.

I have an experience …after reading Sanskrit shloka s your brain starts working in a positive way…it repairs if you are hurt before or gone through any kind of depression..it’s very powerful…I think even in schools they should start telling children the importance n the power of Shloka s…🙏🏻
