The Harappans spoke vedic sanskrit which they
called Bharata. The name Bhaarata comes from the name of the Harappan language.It is the language of the Bharats.
The study of the Harappan seals confirms the vedic way of life with rituals ranging from the Raajasuuya where a king
was sacrificed to animal sacrifices including the buffalo.

The Harappans ,Sumerians,Akkadians and Egyptians were linked
by a cultural link which had a common source point

which is Bharata itself. Comparative study of the languages reveal this.
