A brief review of the previous talk (The Progress Of Insight - Part 1) followed by a discussion of what is called "The Arising and Passing Away Of Phenomena" stge. The "Ten corruptions Of Insight" are described, and how to relate to these with skill.
One way to think of dharma practice is as a path of purification. The talk uses a discourse by the Buddha's as a way to describe this process. We can see how, little by little, over time we are purifying the mind and heart. The key is to keep facing in the right direction as we develop increasingly wholesome thoughts, words and actions.
