Joseph Goldstein on Vipassana Meditation

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.
