Vipassana means "to see things as they really are". It is a process of self-purification by self-observation. It is an ancient technique from India, which was originally taught by Gautama, the Buddha.
As the principal teacher, Goenkaji, as he is known has been instrumental in the spread of Vipassana in modern times.
" The only conversion involved in Vipassana is from misery to happiness, from bondage to liberation, "
- S.N. Goenka
