Mahasi Sayadaw
"Vipassanā" practice in the Theravada tradition largely fell out of practice by the 10th century, but was reintroduced in Toungoo and Konbaung Burma in the 18th century, based on contemporary readings of the "Satipaṭṭhāna sutta", the "Visuddhimagga", and other texts. A new tradition developed in the 19th and 20th centuries, centering on 'dry insight' and downplaying "samatha". It became of central importance in the 20th century Vipassanā movement as developed by Ledi Sayadaw and U Vimala and popularised by Mahasi Sayadaw, V. R. Dhiravamsa, and S. N. Goenka.
