Mindfulness-Based Stress Reduction (MBSR): Though it has its roots in Buddhist meditation, a secular practice of mindfulness has entered the mainstream in recent years largely through the work of Jon Kabat-Zinn and his Mindfulness-Based Stress Reduction (MBSR) program, which he launched at the University of Massachusetts Medical School in 1979. The MBSR program usually has students meet for two to three hours per week for eight weeks, practicing at home between classes. They learn practices such as the "body scan," in which they focus their attention along each part of the body, trying to be aware and accepting of whatever they sense in these body parts, and the "raisin meditation," where they slowly use all of their senses, one after another, to observe a raisin in great detail, from the way it feels in their hand to the way its taste bursts on the tongue.
