Yeah, this is also what I gathered from speaking to people from India, and my own research. Brahmanism/ belief in the vedas was pretty widespread and sanskrit is with a few local exceptions the “Latin” of India. As far as I know there was relatively little iconoclasm as most follow up empires usually respected what came before. The exception might by in the deep south? Not sure. Ofcourse this changed somewhat with islamism and British rule. Those two things reformed a lot in the identities of people during time up till now.
