Continuing the ongoing discussion of the Seven Factors of Awakening, this week the focus is on two of them: dhamma vicaya (Investigation of mind states) and viriya (Energy, or Right Effort).  Peter pointed out that investigation, effort and joy are energizing factors, while tranquility, concentration and equanimity are calming factors; mindfulness monitors their action and coordinates their mutual influence of each other.  Investigation and effort are linked to vitakka (bringing attention to a mind state) and vicara (sustained awareness of the mind state).  Right Effort is explained in terms of four applications, in order to eliminate the unwholesome mind states and maximize the ongoing effect of wholesome mind states.  The entire process is considered as the practical description of vipassana (insight into the true nature of reality).
