Mahasi Sayadaw
Buddhist Meditation is a popular and widespread Buddhist practice in Burma. It is done by both laypersons and monastics. Though traditionally, most laypersons (and even most monks) did not focus on meditation, this changed with the growth of a mass lay meditation movement (a.k.a. the "vipassana movement") in the 20th century. It was led by figures such as Mahasi Sayadaw, U Nu and U Ba Khin, who promoted the idea that even laypersons could strive for awakening through meditation practice.
