John Earl Coleman is a teacher of Vipassana (insight) meditation, a kind of meditation of Theravada Buddhism. He was born in 1933 in a mining town in Pennsylvania, US. After attending his studies, he served in the Army. He went to Korea during the war. After he came back to the USA, he started to work for the Central Intelligence Agency (CIA). From the end of the 50's through the beginning of the 60's, he worked for the administration in Thailand. He worked officially for S.E.A. Supply Corporation, advisers to the government of Thailand, as a specialist in criminology.
In these years in Thailand, he started to be interested in Vipassana meditation. He had embarked on a vigorous pursuit of a different sort: a quest for spiritual truth.
Coleman traveled through India, Burma, Japan and Thailand and encountered such legendary teachers as Jiddu Krishnamurti, Maharishi, D.T. Suzuki and Sayagyi U Ba Khin. His search for peace of mind and liberating insights came to fruition in Yangon (Rangoon) under the tutelage of the great Vipassanā meditation master U Ba Khin, who had established the International Meditation Center.
