Three times last week, between classes in neuropharmacology, neural systems and journalism, Brown University junior Henry Langton changed into sweatpants, sat with dozens of classmates on cushions in a campus dance studio and meditated on his breath and his body for 25 uninterrupted minutes.

One day, the focus was bamboo breathing, a Zen breath control technique. Another day, it was the Heart Sutra, a Mahayana Buddhist scripture frequently chanted in Zen monasteries. There was also walking meditation, a mindfulness of the body exercise done while moving through the room.
