A meditation study led by Harvard Researchers showed that it only took eight weeks of meditation, to actually produce a physical change in the brain’s gray matter.
A total of 12 people participated in the Mindfulness-Based Stress Reduction (MBSR) Program at the University of Massachusetts Center for Mindfulness. They took 2 weeks off before and after the program and magnetic resonance (MR) images were taken of their brain. They also had weekly mindful meditation meetings where they were given audio recordings to practice their guided meditation, they also had to log how much time they spent meditating throughout their day.
