Vipassana meditation courses (Dhamma.org)

The Vipassana courses taught by S. N. Goenka, in the line of Sayagyi U Ba Khin, pass on a technique of observing bodily sensations that this tradition traces back to the Buddha himself. The format is demanding and sober: ten residential days of silence, with a daily discipline of many hours of meditation and recorded talks explaining the method. Nothing is charged, not even food or lodging; everything is sustained by donations from those who have already completed a course. There are centres on every continent, and the website, in dozens of languages, lists each centre's calendar.
