The festival is believed to originate from the celebrations dedicated to water spirits in ancient times. Today it is more of a tradition and a chance to make a wish and ask higher powers for help. The essence of the festival is the floating of little baskets made of banana leaves and decorated with flowers. There also is a candle inside the basket, which is later lit.
The baskets are then pushed to water to take all the wishes to the spirits and bring you back the wish you asked for. The festival is celebrated throughout the country and often incorporates beauty contests and other similar activities.
