"Admittedly, the Vedas are a defective source of history. As religious books, they only deal with historical data in passing. But that has never kept the invasionist school from treating the Vedas as the only source of ancient Indian history, to the neglect of the legitimate history books, the ItihAsa-PuraNa literature, i.e. the Epics and the Puranas. It is like ignoring the historical Bible books (Exodus, Joshua, Chronicles, Kings) to draw ancient Israelite history exclusively from the Psalms, or like ignoring the historians Livius, Tacitus and Suetonius to do Roman history on the basis of the poet Virgil. What would be dismissed as “utterly ridiculous” in Western history is standard practice in Indian history."
