Arul, abt the cow workship and Aryan link - it is the popular belief. After seeing the life’s of the Suri tribe i no longer accept this theory.
There are lots of tribes all over Africa, but the Suri's way of life is remarkably similar (u have to see to believe) to the Tamil village way of life. I am convinced of a direct link.
If the jinx of the Indus civilization is to be broken, we have to think out of the box. I think the regular line of accepted history doesn't hold water.
