 On Ok Phansa day, the 15th day of the 11th waxing moon, Lord Buddha had come back to Earth and made the miracle that all realms (heaven, human, and hell) can see each other while he was going down.The next morning, most citizens made a big "Tak Bat" event as they had not seen Lord Buddha for almost three months.That event was originally called "Tak Bat Theworohana", but as the time passed, it had derived to only "Tak Bat Thewo".
