It is certain ... that the Rigveda offers no assistance in determining the mode in which the Vedic Aryans entered India., .. If, as may be the case, the Aryan invaders of India entered by the western passes of the Hindu Kush and proceeded thence through the Punjab to the east, still that advance is not reflected in the Rigveda, the bulk at least of which seems to have been composed rather in the country round the Sarasvati river, south of the modern Ambala.

What Witzel actually does is as follows: he draws up a geographical picture for each MaNDala of the Rigveda; and then, on the principle “the more western the geography of a MaNDala, the older the MaNDala”, he prepares a chronological grid arranging the MaNDalas in such a way as to show a movement from west to east. “Pedigrees of chiefs and poets” play no role at all in this chronological grid!... What is more, even the geographical picture for each MaNDala, as drawn up by Witzel, is based on the manipulation and misinterpretation of geographical data, manipulated to show this movement.

An analytical examination of just the three following assertions by Michael Witzel provides us with a great many examples of this exercise in deception:...Thus there is a regular AIT methodology by which every geographical name or word found in, or missing in, the Rigveda is to be interpreted: every eastern word found in the text is to be treated as indicative of a new area with which the Rigvedic Aryans are newly becoming familiar, and every eastern word not found as indicative of an eastern area not yet known to the immigrating Aryans; every western word found is to be treated as indicative of an area associated with the early days of the Aryan immigrations, and every western word not found as indicative of an area already old and forgotten by the immigrating Aryans

Witzel‘s location of the Sarasvatī in Book 2 in Afghanistan is not an honest one: he does it only because he wants a Rigvedic Book which refers only to western rivers, in order to show the Vedic Aryans ―fighting their way through the NW mountain passes in their alleged movement from west to east, and Book 2 is his only option, since the name of only this one river is mentioned in the whole of this Book, and it is a name which can be manipulated from east to west by creating a dual entity (thanks to the existence of a Sarasvatī, the Avestan Harahvaiti, in Afghanistan).

But this, besides being seemingly "possible" (by straining the credulity of even the most credulous and partisan reader to the utmost limit) only in respect of a very few names, would not help in explaining the almost complete absence of Western geographical data in the Early Books. Therefore, Witzel also tries to transfer eastern geographical data to the west,.... or by creating dual entities (eg. an Eastern Haryana-Sarasvatī, as well as a Western Afghan-Sarasvatī, both referred to in the Rigveda, with Witzel being the only person possessing the key to distinguish which Sarasvatī is being referred to in which verse.

It is difficult to believe that Witzel is serious in his incredible assertions [about the Sarasvati river]... And when other verses do refer to a river of that name, this river may be “anywhere” from Arachosia to the “night time sky”: anything but the Haryana river – the sky is the limit! In his 1995 papers, he locates the Sarasvati in hymn 6.61 squarely in Kurukshetra in his “Geographical Data” (WITZEL 1995b: 343,349) as well as in his descriptions of Mandala 6: “W/NW, Panjab, Sarasvati, Ganga” (WITZEL 1995b: 318, 320). And nowhere in those papers does he suggest anything contrary!

Let us look at the map of Eastern India—starting from the North 24 Parganas district, proceeding through Nadia, Murshidabad, Malda and West Dinajpur before entering the narrow neck of land lying through Raiganj and Dalkola of Islampur sub-division before passing through the Kishanganj district of East Bihar to enter Siliguri. Proceed further and take a look at the north Bengal districts of Darjeeling, Jalpaiguri and Cooch Behar before entering Assam, and its districts of Dhubri, Goalpara, Bonaigaon, Kokrajhar and Barpeta. A more sensitive region in Asia is difficult to locate….

However it might be ... [regarding the original homeland], both those who advocate the theory that the Aryans came from outside India . . . and those who dispute the foreign theory and believe the Aryans to be autochthons are of the same opinion [that Punjab was the abode of the Rgveda" (Sastri and Srinivasat Chari 1971, 2; )

These dates Mueller later insisted were minimum dates only, and latterly there has been a sort of tacit agreement... to date the composition of the Rigveda somewhere about 1400-1500 BC, but without any absolutely conclusive evidence.

The Indus-Sarasvati Civilization is found extending for more than 1600 km from north to south and equally from east to west, covering an area of about 2.5 million sq. km and more. The northernmost site known to us so far is Manda, located on the River Beas near Jammu; the southernmost site is Bhagatrav on the RiverTapti in Gujarat; the easternmost site is Bhorgarh in east Delhi and Alamgirpur in district Meerut; and the westernmost site is Sutkagendor, located on the ancient shore of the Arabian Sea, near the eastern border of Iran. The Indus-Sarasvati Civilization was, therefore, around four times more in area coverage than any contemporary civilization, including the Egyptian and the Mesopotamian.

On the other hand, northern India is the only place where place-names and river-names are Indo-European right from the period of the Rigveda (a text which Max Müller refers to as “the first word spoken by the Aryan man”) with no traces of any alleged earlier non-Indo-European names.

In at least three passages of the Rigveda mentioning the Sarasvatī, a river corresponding to the present Sarsuti and Ghaggar is meant. For this we have conclusive evidence in the famous hymn, the ‘Praise of the rivers’ (Nadistuti) which, with a precision unfortunately quite exceptional in Vedic texts, enumerates the Sarasvati correctly between the Yamuna (Jumna) in the east and the Sutudri or Sutlej in the west... ‘of old sites on its banks’ would ‘be helpful to the student of early Indian history, still so much obscured by the want of reliable records and the inadequacy of archaeological evidence.’

The most sacred and eastern source of the Sarasvatī is said to be Adi-Badri Kunda north of Katgadh [Kathgarh], while the latter is still remembered to be the place where the sacred stream came out of the hills.

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.
