Phra That Phanom, a sacred place of the northeastern Thailand
The Chedi where Buddha's breastbone is contained is located in That Phanom District, Nakhon Phanom Province. Phra Ajaan Sao Kantasilo and Phra Ajaan Mun Bhuridhatto used to travel to the Chedi which, at the time, was a deserted place covered with vines. They stayed there and renovated the Phra That Phanom Chedi. Nowadays, the Chedi is one of the most important religious places in Thailand.
