Wat Liab, Mueang District, Ubon Ratchathani
Phra Ajaan Mun had practiced meditation with Phra Ajaan Sao Kantasilo at Wat Liab. Then, he traveled to various places before once again returning to the temple to visit and pay respect to Phra Ajaan Sao. Phra Ajaan Mun had been practicing meditation so intensely that he could see a mental image while sleeping and meditating. The occurrences encouraged him to train himself to a greater extent.
