Vipassana movement
The Vipassanā movement refers to a branch of modern Burmese Theravāda Buddhism that promotes "bare insight" (Sukkha-Vipassana) meditation practice to develop insight into the three marks of existence and attain stream entry. It has gained widespread popularity since the 1950s, including through its Western derivatives, which have been popularised since the 1970s, giving rise to the more dhyana-oriented mindfulness movement.
