That is, none of the Rishi ascriptions (either for an allegedly “original” hymn or an allegedly “interpolated” hymn) shows a contrary order: i.e. if … - Shrikant G. Talageri

But Jahnāvī is typically a Rigvedic form of the post-Vedic Jāhnavī, and it does not require any "Epic/Purāṇic concepts" to recognize it as the name of a river: a river is a geographical feature, not a mythological entity whose identity is based on traditional historical or mythological texts. On the other hand, Witzel‘s claim that ―Jahnāvī was the wife or a female relation of Jahnu or otherwise connected to him or his clan is definitely based on Epic/Purāṇic concepts: no person named Jahnu is mentioned anywhere in the Rigveda,...Jahnu himself is an Epic/Purāṇic figure...Not only does Witzel accept this Epic/Purāṇic person as the source of the Rigvedic word Jahnāvī, he even visualizes, in the manner of the Amar Chitrakatha comic books, a mysterious lady named Jahnāvī, "the wife or a female relation of Jahnu or otherwise connected to him or his clan", whose very existence is completely unknown to the whole of Vedic and Epic/Purāṇic literature and Indian tradition, but who is apparently so very important in the Rigveda that she is mentioned twice (how many other ladies are mentioned twice in the Rigveda outside of references to people aided by the Aśvins?) in special references, which are worded so peculiarly (what, after all, unless she was a symbol of the motherland, like the present-day Bhāratmātā, has this lady to do with an ―ancient home), that they can be more conveniently and logically translated as references to a river!

“Indian culture being the greatest and richest is not a narrow or chauvinistic idea; it is a demonstrable fact. It would be chauvinistic if it acquired an imperialist tinge: that other cultures are inferior and Indian culture must dominate over or replace them. In fact, I am opposed to even internal cultural imperialism. The idea that Vedic or Sanskrit culture represents Indian culture and that other cultures within India are its subcultures and must be incorporated into it, is wrong…. all other cultures native to this land: the culture of the Andaman islanders, the Nagas, the Mundas, the tribes of Arunachal Pradesh, etc. are all Indian in their own right. They don’t have to be – and should not be – Sanskritised to make them Indian”.

Sergent’s last thrust represents the unkindest cut in this whole smear campaign. It is not we who have avoided debate. It is these Western scholars who have chosen to conduct a spit-and-run campaign from a safe distance, while restricting their criticism of our theory (elaborated by us in our earlier book) to name-calling and label-sticking rather than to demolition of our arguments.
