While preparing for overseas deployment with the U.S. Marines late last year, Staff Sgt. Nathan Hampton participated in a series of training exercises held at Camp Pendleton, Calif., designed to make him a more effective serviceman.

There were weapons qualifications. Grueling physical workouts. High-stress squad counterinsurgency drills, held in an elaborate ersatz village designed to mirror the sights, sounds and smells of a remote mountain settlement in Afghanistan.
There also were weekly meditation classes — including one in which Sgt. Hampton and his squad mates were asked to sit motionless in a chair and focus on the point of contact between their feet and the floor.
“A lot of people thought it would be a waste of time,” he said. “Why are we sitting around a classroom doing their weird meditative stuff?
“But over time, I felt more relaxed. I slept better. Physically, I noticed that I wasn’t tense all the time. It helps you think more clearly and decisively in stressful situations. There was a benefit.”
