Goenkaji

S N Goenka has played a large part in the spread of Vipassana meditation
around the world in since 1969. He has taught hundreds of thousands of
people the practice and through his hundreds of appointed teachers
millions have come into contact with the pure dhamma.

The International Dhamma website has
information on around 100 centres all around the world. The teaching is
very much non-sectarian. It is the scientific study of mind and matter
to follow the path out of suffering as taught by the Buddha.
