During mid November to December, the water level swells up on both sides of the river bank clearing the surface for a glittering full moon memorable event of Loi Krathong.
In the beginning, before receiving the famous name of Loi Krathong, it was called Chong Pa Rieng- floating lantern of royal ceremony. It is a Brahman ceremony to worship Gods- Siva, Vishnu, and Brahma. When Thai people adopted Buddhism, they adapted this ceremony to honor the Buddha’s cremated bone- the original Buddha at the second heaven ruler. They floated lantern to worship the foot-print of the Buddha on Nammathanati River beach in India.
