To get any material evidence on our Ancient History which is closely related with Indian texts of contemporary period, Archaeological Survey has to be carried out all through this vast nation. whether any steps have taken until now... we see in our lives many Ancient Marvels in the form of temples and forts, etc., are being spoiled without any care from either ASI or State & central Govts. In this situation on what basis ASI is talking abt material evidence? how many places they have investigated & conducted a well planned proper survey?
