The Buddhist centre called Pha Sorn Kaew is surrounded by high mountains. There the preaching hall is located while a cave is at mountain’s summit. Many Thang Daeng villagers have seen a crystal marble floating on the horizon and disappearing in the cave. They believe that the marble, in fact, is the Holy Relic coming down to the sacred place, so Phra Sorn Kaew, the hidden cliff of marble. This Buddhist site surrounded by mountain ranges is a peaceful place to withdraw and contemplate the deeper teaching and practice of Buddhism.
