Ajahn Chah was a Thai Buddhist monk of the Thai forest tradition, a lineage of strict, meditation centered monastic practice that traces its modern revival to Ajahn Mun Bhuridatta, a documented lineage distinct from a school he founded without any prior teacher of his own. He spent years in wandering ascetic practice, some of it under Ajahn Mun's own direct guidance, a documented formation distinct from training completed within a single settled monastery.
In 1954 he founded Wat Nong Pah Pong, a forest monastery in Ubon Ratchathani province in northeastern Thailand, a documented act of institution building distinct from continuing as an itinerant teacher with no fixed community. He built it into a major center of forest practice with numerous branch monasteries, a documented growth distinct from a single monastery that remained isolated and unreplicated.
