The Shamatha Project
Meditation offers many benefits to mental and physical health. The Shamatha Project, the most comprehensive study of meditation to date, investigates the psychological and physiological processes underlying such benefits. In a randomized, controlled study, we studied how intensive meditation training affects how people think and feel. We employed cognitive and perceptual tasks, emotional provocation, questionnaires, and physiological and biochemical monitoring to assess people’s skills and behavior before, during, and after long-term, intensive meditative practice.
