Ajahn Chah was born on 17 June 1918 near Ubon Ratchathani in the Isan region of northeast Thailand. His family were subsistence farmers. As is traditional, Ajahn Chah entered the monastery as a novice at the age of nine, where, during a three-year stay, he learned to read and write. He left the monastery to help his family on the farm, but later returned to monastic life on 16 April 1939, seeking ordination as a Theravadan monk (or bhikkhu).[6] According to the book Food for the Heart: The Collected Writings of Ajahn Chah, he chose to leave the settled monastic life in 1946 and became a wandering ascetic after the death of his father.[6] He walked across Thailand, taking teachings at various monasteries. Among his teachers at this time was Ajahn Mun, a renowned meditation master in the Forest Tradition. Ajahn Chah lived in caves and forests while learning from the meditation monks of the Forest Tradition. A website devoted to Ajahn Chah describes this period of his life:
For the next seven years Ajahn Chah practiced in the style of an ascetic monk in the austere Forest Tradition, spending his time in forests, caves and cremation grounds. He wandered through the countryside in quest of quiet and secluded places for developing meditation. He lived in tiger and cobra infested jungles, using reflections on death to penetrate to the true meaning of life.[6]
