"[N.K. Verma's] “discovery of Indus Valley script amongst the Santhals of Bihar-Bengal border, after an uninterrupted gap of three thousand and five hundred years time span and at a geographical distance of 2500 miles. (...) He solved this riddle by learning the unique symbols with sound-value which are used by the Santhals of Sahibganj area during their religious rites. (...) Controversy may arise on the point of accuracy or correctness of what Verma has deciphered in the symbols that have been used by the Santhals of Sahibganj. But none is to controvert the fact that the Santhals of the 20th century AD have been scrupulously using the scripts of the 16th century BC independently.”"
