The Vipassanā movement refers to a branch of modern Burmese Theravāda Buddhism that promotes "bare insight" (Sukha-Vipassana) meditation practice to develop insight into the three marks of existence and attain stream entry. It 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.
The Burmese Vipassana movement has its roots in the 19th century, when Theravada Buddhism came to be influenced by Western modernism, and some monks tried to restore the Buddhist practice of meditation. Based on the commentaries, Ledi Sayadaw popularised Vipassana meditation for lay people, teaching samatha and stressing the practice of satipatthana to acquire Vipassana (insight) into the three marks of existence as the main means to attain the beginning of awakening and become a stream-enterer. It was greatly popularised in the 20th century in traditional Theravada countries by Mahasi Sayadaw, who introduced the "New Burmese Satipatthana Method". It also gained a large following in the West, due to Westerners who learned Vipassana from Mahasi Sayadaw, S. N. Goenka, and other Burmese teachers. Some also studied with Thai Buddhist teachers, who are more critical of the commentarial tradition, and stress the joined practice of samatha and Vipassana.
