Mindfulness is everywhere, from the cover of TIME magazine to segments on every major news network. With such popularity in mainstream culture for mindfulness, it was only a matter of time before psychology embraced the approach by offering a burst of mindfulness-based therapies, such as mindfulness-based stress reduction, mindfulness-based cognitive therapy, and mindfulness-based eating awareness therapy. These approaches claim mindfulness as a central theme, yet debate has grown over the role of mindfulness in psychotherapy and biofeedback, and there is growing concern about secularizing a philosophy originating in Asia over 2,000 years ago. This paper will define mindfulness from both traditional and modern perspectives, review the skills and practice of mindfulness, examine the connection of mindfulness and health, and show how, as a process, mindfulness is incorporated in virtually most forms of psychotherapy as well as biofeedback training.
