This is a guided vipassana meditation and lecture from Joseph Goldstein, a senior teacher at the Insight Meditation Society. The first 20 minutes is a guided meditation; the next 40 minutes is a lecture on mindfulness; and the rest is a question and answer time. Goldstein defines mindfulness as "observing present experience, free of any filters" (41:30). This is sometimes stated as "non-judgmentally" observing present moment experience. Right Mindfulness is the seventh step of the Buddhist Eightfold path.
