Even Science agrees to the power of chanting of Vedic Mantras.
World renowned neuroscientist and a Sanskrit devotee, Dr. James Hartzell coined the term “The Sanskrit Effect”.
He conducted an experiment to study the brain of Sanskrit scholars & found that memorising and chanting Sanskrit mantras leads to increase in the size of the brain regions associated with cognitive functions. Since times immemorial, Vedas have been kept alive and transferred from one generation to next, by speech alone!
That’s how powerful Vedic chanting is.
In Dr. Hartzell’s own words “I noticed that the more Sanskrit I studied & translated, the better my verbal memory seemed to become. Fellow students & teachers often remarked on my ability to exactly repeat the lecturers’ own sentences when asking them questions in class.”
