Swastik is normally believed to be an amalgam of the words Su and Asati. Su means ‘good’ and Asati meant ‘to exist’. So in the rules of Sanskrit grammar, the words Su and Asati become Swasti. Thus, the literal meaning of the term Swastika would be ‘let good-prevail’. Swastik is the sign of lord Ganesha and it is believed where there is the Ganesha symbol, nothing bad can happen.
