Thee have been several approaches to understand the Indus Valley script.
After trying out a multilingual approach, it is now evident that the best approach to decipher the Indus Valley scripts is through Tamil, a language of Great antiquity which it shares with Sanskrit.
Please read m post Million eras old Tamil quotes Vedas, the quote Tamil.
Despite repeated concerted attempts to divide Indians and Hinduism b bringing in , now disproved , Aryan Invasion Theory, facts come to light.
Even in the paper , from which I am posting excerpts,the author tries gamely to trace the Tamil language to Sahara, then from there to Iran.
What he missed out is Iran was  apart of Bharatavarsha and kandhara, present Kandahar, was the birth place of Gandhari, wifre of Dhritharashtra, mother  of the Kauravas of  Mahabharata.
So compelling is the evidence that he is forced to conclude,albeit grudgingly,
” The Indus Valley inscriptions were
written in Tamil. It was a syllabic writing
system related to linear Elamite writing
and Proto-Sumerian seals21,22. The Indus
Valley writing was probably not used to
write the Indo-Aryan language because
the Aryan speakers did not arrive in
India until after 1600 BC (refs 40 and 41).’
The findings of tamil seals in Indusvalle and the Indus valley seals in Adhichanallur in Tamil Nadu has forced him to do so.
Even then, the tenor of the paper is to show that the Tamils and the Vedic people were living independent of each other and the presence of the Tamil seals is by the Tamils settled from Sahara, who were the ancestors of Tamils!
That the archaeological  facts are found in both the places , south and north need not mean that the have been used at different points of Time alone.
The could have been used simultaneously when people lived together, much like the North Indians living in South and the South Indians in the North.
It does mean to convey to the future generations that we have lived separately as distinct group, being mutually exclusive,s but together, though with our own customs and customs adopted from the locals, as we do now.
Excerpts.
From
Dravidian is the language of the Indus writing .
Clyde Winters
The Indus Valley writing is not a multilingual system of writing. The writing indicates that this population
was literate and spoke a Dravidian language. The study also indicates that the Indus Valley writing was not
used to write an Indo-Aryan language, because the Aryans did not arrive in India until after 1600 BC.

Yes I agree – Sanskrit and Tamil are so closely intertwined and Tamil as 2nd most ancient classical language after Sanskrit.
This has also got enough support from our Mythology too. Karthikeya or Subrahmanya was known for his tantrums and used get angry with Shiva and Parvathi. In one such occasion, he vows to create his own language for his people and comes to a place called ‘Palani’ (Phalam Ni) to start his campaign. So, it can be believed that Tamil is as old as Karthikeya.
Some of the names of Karthikeya
Saravana or Sharavana – as he born on a particular type of grass found on banks of river – Sharvana bhava
Shanmukha or Aarumugam – Aaru is Shasti or six and Mukham got converted to Mugam in tamil.
Murugan – In Sanskrit, ‘Murug’ means ‘Snake hole’ as Murugan or Karthikeya is also being depicted as Kundalini shakthi or Serpent form is also considered as equivalent.
There is a place called “Mopi Devi” in Krishna Dt, AP which houses a Subrahmanya temple and sage Agasthya believed to have found Subrahmanya idol inside a “Snake hole Pit’ and he installed it there as a temple.
Many minds are Shapit by their Karmas and desire , will go to their path of destruction as many do. Ramani ji , many more appreciation for ur great works. Would u like to become an author in of book, I intend to publish. Leave me a reply are pparihar2011@gmail.com

As a matter of fact, I have been thinking on the lines of publishing Books from the posts I have written.I shall be mailing you.Thanks and Regards
Mr krishnmurty- open eyes . Aryan invasion theory is debunked by archeologist and historians in USA . Now I know why india can not learn its subduction from false theory that divide india. Illiteracy is in mind and literacy can not be achieved just by reading books or passing exam.
people have been travelling across regions in the past and intermingling; knowledge of it does not divide us;
Aryans came to india from central asia as cowherds looking for pasture land; they brought their language, culture and religion;
brahui, a Dravidian language is still spoken in Baluchistan; it only proves the Aryan invasion theory; before the Aryans the whole of india was Dravidian;
This fact only confirms that Tamil was there, not that there was Aryan Invasion..Please read m post The fraud called Aryan Invasion’
