Dr. S. Kalyanaraman quotes all the primary historical sources that lead us to de-codification of the Sarasvati Sindhu civilization. He says that Neolithic culture has emerged in different parts of Bharat. The maps of post Harappan Iron Age pottery sites in the greater civilization in Asia right up to Middle East and Iran are available. The seals and hieroglyphs are not just artifacts, they depict entire lifestyle and the professions like guild master, wealth keeper, blacksmiths, metal alloy artisans, jewels and gems artisans etc. The remarkable documentation of professions is engraved in metal tablets There is a very clear communication through hieroglyphs which can relate to almost all the Indian languages. The symbols can be easily connected to the Meluhan languages which signify the groups of Bharat languages.
Most of the Meluhan words or ancient Indian languages words are all traceable to the Prakratam versions of the ancient languages of Sarasvati Sindhu civilization. Art and cultural traditions have helped to pass on the ancient traditions through temple sculptures and religious practices. Tantra-yukti is also a research methodology commonly used by researchers that helps to analyse, was used by Panini before common era, later by Charak and Kautilya, now used by scientists.
