The symbol of Svastika (an auspicious symbol) represents the element of Ganesha. It is a tradition to draw this symbol in houses on all occasions - big or small, at all festivities and at holy places or places where offering is performed. Even villagers pray to this mark as a symbol of Ganesha.
Today the swastika remains a necessary symbol of sacredness and well-being on all occasions of worship not only amongst Hindus but almost all communities.
