LP Waen (B.E.2431~2528) hometown was in Leoi Province, North-East of Thailand, also known as Issan. At the age of 13, he became a novice monk in Wat Poh Chai and he studied the Dhamma. He was very good in Pali and Dhamma, even at that young age. He went Tudong with his teacher, Ajarn Wuan, travelling from Leoi to Ubon province. After he reached Ubon, he learned Dhamma from another teacher, Ajarn Sing. During his Tudong, he met many disciples of Ajarn Man in the forests and they told him that Ajarn Man is very good in Sammadhi and Dhamma.
LP Waen endured all kind of difficulties during his Tudong, where he encountered ghosts, wild animals and other dangers. He was not afraid of danger, even the villagers told him that the places were dangerous and eerie, and full of evil spirits. LP Waen just went ahead because he wanted to learn from all these experiences. He spent most of his monkhood as a forest monk, travelling from one province to another on foot, climbing hills, crossing rivers and deep forests. He had also went as far as Laos, Cambodia, Burma and even Vietnam on Tudong.
At aged 39, LP Waen arrived in Lampang and was told that Ajarn Man was in Chiang Mai. LP Waen quickly went there to look for Ajarn Man and finally met him at Wat Jedi Luang. Ajarn Man accepted LP Waen as his disciple and he studied Dhamma at Wat Jedi Luang.
He stayed at Wat Huainumrin for ten years and during his long stay in Wat Huainumrin, he stayed most of his time in forests and only went to the temple during the rainy seasons. At B.E.2505, Ajarn Noo, the abbot of Wat Doi Mae Pang asked LP Waen to stay in Wat Doi Mae Pang because he treated LP Waen as a teacher. After Ajarn Noo passed away, the villagers persuaded LP Waen to become the abbot of Wat Doi Mae Pang.
LP Waen was very skillful in Sammadhi and Dhamma. LP Waen does not like crowded places and loved to live alone in the forests, just like his teacher, Ajarn Man. Some people said that LP Waen had achieved Arahang level. Than Chow Koon Nor ever mentioned that "there is a Phra Arahang, but he lives far away, in the forest hill".
LP Waen stayed in Wat Doi Mae Pang until he passed away, living the life as a forest monk all the time in a small hut away from the temple.
