At the age of eleven, he was ordained as a novice at the village monastery, and stayed there with his uncle who was a resident monk. During a year and six months in the monastery, he studied Laotian scripts and ancient local scripts. He also started practicing various meditation methods, such as the Budh-dho and Breath Counting methods. After disrobing, he returned to his home.
He used to spend all day diligently working in the fields.
Following tradition, he was ordained as a monk at the age of twenty. Again he studied and practiced meditation with his uncle for six months. After returning to lay life, he was married at twenty-two and had three sons. In his village, he was always a leader in Buddhist activities and was highly respected and chosen to be the head of the village on three different occasions. Despite of heavy responsibilities, he continued his meditation practice regularly.
Later he moved to Chiengkhan, a larger community, where his sons could attend school. Being a merchant, he sailed his steamboat along the Maekhong River between Chiengkhan-Nongkai-Vientiane, or even as far as Luangprabang. He had opportunities to meet several meditation masters and his enthusiasm in pursuing Dharma (the Truth) continued to strengthen. Furthermore, he began to realize that many years of being good, making merit, and practicing various methods of meditation had not liberated him from his anger. Finally, he determined to start searching for the way out.
In 1957, when he was nearly forty-six, he left his home with firm determination not to return unless he found the Truth. He went to Wat Rangsimukdaram, Tambol Pannprao, Amphur Tabon in Nongkai Province and practiced a simple form of bodily movements except that he did not follow the formal rituals and recitation of the words like others did. What he did was only being aware of the movements of the body and mind. Within a couple of days, on the early morning of the eleventh day of the waxing moon, the eighth month of 1957, his mind reached the End of Suffering completely without traditional rituals or teachers.
Later he returned home. He taught his wife and relatives what he had found for two years and eight months, as a lay teacher. He then decided to re-enter monkhood in order to be in a better position to teach the people. The ordination was made on February 3, 1960.
His teachings were spreading across the country as well as outside. He devoted his life to the teaching of Dharma despite his poor health. He was diagnosed to have stomach cancer (malignant lymphoma) in 1982. In spite of his illness he continued his work actively and incisively until the end of his life.
On September 13, 1988 at 6:15 PM., he passed away calmly at the age of seventy-seven in a hut on Koh Buddhadhamma, Tabb Ming Kwan, Tambol Gudpong in Loei Province.
