We are all capable of living in Walter Mitty type worlds, of placing too much importance on what is going on in the mind rather than taking time to experience what is really happening in this moment.
The premise that we live in a constructed “virtual world” of our own making is of fundamental importance in mindfulness based stress reduction. Formal mindfulness techniques (body scan, sitting meditation, Hatha Yoga) are contextualized by statements such “everyone’s experience will be different and unique,” and a de-emphasis on generic goals such as relaxation or insight. Instead, the importance of “just noticing” events in the moment-by-moment flow of experience is emphasized, without trying to make anything in particular happen. Non-judgmental awareness is at the core of mindfulness practice, emphasizing clarity of perception and freedom from cognitive preconceptions.’
