During the 20th century, the Burmese vipassana meditation movement also continued to grow and expand. Numerous monks and lay students developed various methods of meditation and there are many meditation centers and meditation monasteries. Influential figures of 20th century Burmese Buddhist meditation include U Nārada, Mahasi Sayadaw and Sayadaw U Pandita (who promoted what is called the "new Burmese method"), Webu Sayadaw, U Ba Khin and his student S.N. Goenka, Mogok Sayadaw, Sunlun Sayadaw, and Pa Auk Sayadaw (who emphasizes the jhanas as taught in the Visuddhimagga). Numerous western students also studied Burmese Buddhist meditation and brought them to the west as part of what is sometimes called the insight meditation (or vipassana) movement. This includes figures like Jack Kornfield, Joseph Goldstein and Sharon Salzberg.
