Myanmar, or Burma as the nation has been known throughout history, is one of the major countries following Theravada Buddhism. In recent years Myanmar has attained special eminence as the host for the Sixth Buddhist Council, held in Yangon (Rangoon) between 1954 and 1956, and as the source from which two of the major systems of Vipassana meditation have emanated out into the greater world: the tradition springing from the Venerable Mahasi Sayadaw of Thathana Yeiktha and that springing from Sayagyi U Ba Khin of the International Meditation Centre.
