This is the second in a series on the Seven Factors of Awakening, focused on mindfulness.  The discussion reviews the classical commentaries on the nature and purpose of mindfulness, as well as the ways mindfulness can be cultivated through sitting practice and lifestyle choices.  Additionally, Peter reviews current neurological research on how mindfulness is manifested in the brain.  The concept of metacognition, currently being researched to understand the process of learning is also discussed.
