Another duty to be done during the Songkran Festival is a religious service called Bangsakun performed in sacred memory to the dead. When a person died and was cremated, the ashes and charred bones of common people were buried at the root of a sacred fig-tree in a wat. Such trees are to be found in the grounds of almost every wat. It is a symbol of the Lord Buddha's enlightenment for under such a tree did Buddha sit in meditation and receive his enlightenment. If a person is able to erect a Pra Chedi or pagoda in the wat the ashes and bones are then deposited in it. In later times a portion of the bones was sometimes kept in the house in a receptacle. On Songkran Day a religious service in sacred memory to the dead may be officiated by a monk or monks at the place where the ashes and the bones have been deposited, or as in some localities the people bring their dead bones to a village wat in company with others where a joint memorial service is performed. In some parts of the country the guardian spirits of the village and town receive also their annual offerings on Songkran Days. Obviously there are reminiscences or traces of ancestor and animistic worship in by-gone days.
