One of the most well-recognized Western definitions of mindfulness comes from Jon Kabat-Zinn, one of the central founders of the field and creator of Mindfulness-Based Stress Reduction (1979):
Kabat-Zinn’s use of the term mindfulness has become a landmark definition but similar conceptual definitions also include:
An open and receptive attention to, and awareness of, what is occurring in the present moment
An attention that is receptive to the whole field of awareness and remains in an open state so that it can be directed to currently experienced sensations, thoughts, emotions, and memories
Waking up from a life lived on automatic pilot and based in habitual responding
The basic human ability to be fully present, aware of where we are and what we are doing, and not overly reactive or overwhelmed by what is going on around us
