The awareness that emerges through paying attention on purpose, in the present moment, and nonjudgmentally to the unfolding of experience moment by moment.
The awareness that results from (1) self-regulation of attention so that is maintained on immediate experience, thereby allowing for increased recognition of mental events in the present moment and (2) the adoption of a particular orientation toward one’s experiences in the present moment, an orientation that is characterized by curiosity, openness, and acceptance.
