Khruba Chaiyawong was born as
Chaiwong Taenam () on 22 April 1913 at 00:15, in the year of the Ox, to Noi Chanta and Bua Kaeo. His family were poor farmers devoted to
Buddhism. At age 12, he adopted a
vegetarian diet and became a novice under
Khruba Chaiyalangka, receiving the Dhamma name Jayalaṅkā. As a novice, he endured physical bullying from peers but remained patient and forgiving. He traveled with Khruba Chaiyalangka to various locations and later received
full ordination at
Wat Phra Phutthabat Tak Pha on 2 February 1933 (modern reckoning: 2 February 1934), under
Khruba Brahmachak, taking the Dhamma name Jayavaṃsā. He traveled further and converted a local
Karen community, who settled around Wat Phra Phutthabat Huai Tom and adopted his practices. At age 22, upon learning that
Khruba Siwichai was leading locals to build the road to
Wat Phra That Doi Suthep, he helped lead a group of Karen volunteers to assist. Afterward, he returned to Wat Chom Mok,
Omkoi district. Due to opposition against Khruba Sriwichai, local authorities forced Khruba Chaiyawong to disrobe. He adopted white robes but continued to strictly follow monastic practices. He assisted in restoring
Wat Ban Pang and traveled with Khruba Sriwichai until he died when Khruba Chaiyawong was aged 28. Later, he was re-ordained under
Khruba Bunma of Wat Ban Hong with the Dhamma name Candavaṃso. He restored various temples until aged 34 when he was invited to restore Wat Phra Phutthabat Huai Tom, where he remained for the rest of his life. Khruba Wong suffered from heart disease and received treatment at
Maharaj Nakorn Chiang Mai Hospital until his death on 17 May 2000, aged 87, having served 69 rain retreats. == Ecclesiastical titles ==
