There is a traditional tale in Sinhala folklore about a wall that once separated two villages. The wall was built to mark the boundary and to prevent disputes over land. Over time, however, it became a symbol of division, a constant reminder of the 'us versus them' mentality.

As they worked side by side, they realized that their differences were not as vast as they seemed and that unity was stronger than any barrier.

Wal Katha is not just a form of storytelling; it is an art form that requires great skill and mastery. The Wal Kauthu (storyteller) must possess a deep understanding of the stories, as well as the ability to convey emotions and drama through voice, gesture, and expression. The traditional Wal Katha performance often features music, with the narrator accompanied by a drummer or a musician playing a traditional instrument.
