Thok (ภูทอก) means an isolated mountain in Isan dialect. It consists of two hills: Phu Thok Yai and Phu Thok Noi. Previously, this area was dense woods with many wild animals. Because of its tranquility, Phra Achan Chuan Kunlachettho, a meditation master, initially established a meditation place here for Buddhists to practise the Buddha’s teachings.
