Mindfulness, mindfulness -- what is this mindfulness? There seems to be a big and unfortunate misunderstanding about this.
For some reason many people think mindfulness means to intensely stare at whatever we are doing until our eyes pop out. "I must be aware! What am I doing now? I'm driving, I'm driving... I'm coding, I'm coding... I'm pooping, I'm pooping..." -- but this is not mindfulness, this is generation of anxiety.
The right mindfulness is mindfulness of the subconscious. Mindfulness of our "guts", mindfulness of our feelings, mindfulness of our mind "weather", mindfulness of our non-verbal intellect. When we always maintain such deeper connection with ourselves we can learn to heal our mental and emotional neuroses and recover our Buddha-nature -- our inborn power and sanity.
And in 21st century this means first and foremost recovering awareness of our body, because body is not just the window on the subconscious -- body is the subconscious. I recommend you to read the book "Touching Enlightenment. Finding Realization in the body" by Reginald A. Ray, Ph.D. a favorite student of Chogyam Trungpa Rinpoche.
