„It is true that the Rigveda does not provide us details of the inner layout of these forts, but surely the text was not meant to be a treatise on Vastusastra. May it be remembered that it is essentially a compilation of prayers to gods and should be looked at as such. All the evidence that it provides regarding the material culture of the then people is only incidental.“
