“Mindfulness entails concentrated awareness of one’s thoughts, actions or motivations. Mindfulness involves continually bringing one’s awareness back into the present moment.”
What does it mean to have awareness in “the present moment”? What does it mean to be “present”? Why is it is desirable to be “present”?
Does “being present” require a continuous activity of “gently redirecting” the exploring mind to information that is coming in through the senses? I call it the “exploring” mind because the type of mental activity labeled as “thoughts” has been found to be goal-directed; the analogy is less billiard balls going hither and yon than of seeking resolution of unfinished business.
Note: you don’t need a homunculus for brain/mind processes to be goal-directed.
