The traditional of "Tak Bat Devo" was derived from the word "Devorohana" which means the return of Lord Buddha from Heaven to Earth. At the end of the Rains Retreat (Ok Phansa Day) which falls on the first day of the wanning moon of the eleventh lunar month, Lord Buddha returned to earth and was greeted by a crowd and Buddhist believers who were waiting to offer him food. Uthai Thani Buddhist believers proudly organize the "Tak Bat Devo" Festival as annual tradition at Wat Sangkat Rattana Khiri at the top of Sakaekrang mountain. It attracts the large number of believers from all over the country to participate.
