(Insight Meditation Community of Berkeley) In the Satipatthana Sutta (MN#10), the Buddha's discourse on mindfulness, the Buddha instruct's us to contemplate mindfully, ardent and clearly comprehending each of the four foundations. "Clear comprehension" also translated as "clearly knowing" includes four areas of context for our mindfulness practice. In this talk the first two aspects of Clear Comprehension are explored: "Clear Comprehension of Purpose" and "Clear Comprehension of Suitability of Action."
