"“A very few geographical names appear to be inherited from Indo-Iranian times. For instance, OPers. Haraiva-, Av. (acc.) HarOiium, and OPers. HarauvatI, Av. HaraxvaitI-, both of which in historical times are located in the area of southern Afghanistan (Herat and Kandahar), correspond to the two Vedic rivers Sarayu and SarasvatI. These correspondences are interesting, but tell us nothing about the early geography of the Indo-Iranian tribes.”"
