Mueang Chiang Mai District,
Chiang Mai Province From 1893 Ajahn Mun studied meditation at Wat Liap, and began wandering ascetic pilgrimage (
dhutanga) with Phra Kru Wiwek Buddhakit along the Mekong River on Thai and Laotian sides. With Luang Pu No Thitpanyo, he practiced seclusion at Wat Phra That Phanom Woramahawihan in 1900, inspiring local reverence for the sacred relic stupa, now a major religious monument in northeast Thailand. He wandered through
Ubon Ratchathani,
Nakhon Phanom,
Sakon Nakhon,
Loei Province, and traveled to
Myanmar. In 1912, at Sarika Cave in
Nakhon Nayok Province, he undertook solitary ascetic practice. Despite chronic abdominal pain, he meditated deeply on impermanence and foulness (asubha bhavana), reaching a profound state after three days. He had visions reflecting past lives and renounced delayed aspirations of Buddhahood, resolving for liberation in this life. His mind unified, perceiving the world as calm and smooth, reflecting mind's nature. Afterward, he practiced at Singto Cave, Khao Phra Ngam,
Lopburi Province, then was invited to teach vipassana at
Wat Pathum Wanaram, Bangkok in 1914. In 1915, he returned to
Ubon Ratchathani, residing at Wat Burapharam, then wandered through northeast provinces teaching meditation, gaining many disciples. In 1928, appointed abbot of
Wat Chedi Luang Worawihan in Chiang Mai Province, he reluctantly accepted out of respect for Phra Ubali Khunuphamacharya (Jan Sirijanto). He ordained only one monk, Phra Ajahn Ket Wannako. After one rains retreat, he gave up the abbot position and ecclesiastical rank, emphasizing that attachment to reputation and honor undermines practice. He then wandered northern forests for 12 years, living in districts of Chiang Mai and Chiang Rai Provinces, caring for a benefactor named Mae Bunpan at Ban Mae Koi, where Wat Pa Mae Koi (Wat Pa Phra Ajahn Mun) is now located. Ajahn Mun attained highest enlightenment at
Dok Kham Cave in Phrao District, Chiang Mai Province. He told his disciple
Luang Pu Khao Analayo: "I have finished my work. Now I just weave baskets and help my disciples as I can." He taught many disciples to attain high enlightenment, earning the title
The Great Teacher of the Forest Meditation Tradition. In 1939, invited by Phra Thammachedi (Jum Phandulo), he traveled to northeast Thailand (Isan) to teach meditation. He stayed at several temples including Wat Pa Salawan and Wat Pa Non Niwet, later settling at Wat Pa Ban Nong Phue in Sakon Nakhon Province, devoting himself to teaching until his last days. Luang Pu Mun is revered as the master of the forest meditation tradition of his era. Disciples attest to his vast meditative knowledge and attainment of the
