As one contemplates, penetrating deeper and deeper into the nature of reality, one leaves the sensible world behind, transcends the subject/object mode of perception, and experiences one's soul.
Mindfulness is meditation in action and involves a "be here now" approach that allows life to unfold without the limitation of pre-judgment. It means being open to an awareness of the moment as it is and to what the moment could hold. It is a relaxed state of attentiveness to both the inner world of thoughts and feelings and the outer world of actions and perceptions.
