In Sri Lankan culture, the bond between a mother and son is considered sacred. The Sinhala Wal Katha tradition is a way to strengthen this bond and show appreciation for the love and care that mothers provide to their sons. The custom is usually observed on special occasions such as Vesak (a Buddhist holiday), Mother's Day, or during the traditional Sri Lankan New Year (Aluth Avurudhu).

In Sinhalese culture, the mother-son relationship is often viewed as a symbol of love, care, and devotion. Mothers play a vital role in shaping their sons' values, morals, and personalities.

The mother-son relationship in Sinhala culture is a unique and special bond that is built on a foundation of love, trust, and mutual respect. This relationship is characterized by a deep emotional connection, cultural significance, and a sense of devotion and loyalty. While there are challenges and changes affecting this bond, the essence of the mother-son relationship remains an essential part of Sinhala culture and tradition.
