Two and a half millenniums ago, a prince named Siddhartha Gautama traveled to Bodh Gaya, India, and began to meditate beneath a tree. Forty-nine days of continuous meditation later, tradition tells us, he became the Buddha — the enlightened one.
More recently, a psychologist named Amishi Jha traveled to Hawaii to train United States Marines to use the same technique for shorter sessions to achieve a much different purpose: mental resilience in a war zone.
“We found that getting as little as 12 minutes of meditation practice a day helped the Marines to keep their attention and working memory — that is, the added ability to pay attention over time — stable,” said Jha, director of the University of Miami’s Contemplative Neuroscience, Mindfulness Research and Practice Initiative. “If they practiced less than 12 minutes or not at all, they degraded in their functioning.”
