MAHABHARATA: THE STORY OF ARYANS

Mahabharat is the only vedic text other than RigVeda (the first of the four Vedas) which presents proofs about the original home of the Vedic people.
The RigVeda very clearly talks about the original home of the Vedic people as being destroyed. Following this incident, they took a long journey through sea-route and finally reached the land around the Indus and Saraswati river, which later came to be known as Aryavarta (the land of Aryas). It is not known what actually destroyed their home-land but going by the signs it seems like the ice-age.

-That human races have preserved their ancient traditions is undoubted, though some or many of them may have become distorted in course of time, and it is for us to see if they do or do not accord with what we know of the ancient man from latest scientific researches. In the case of the Vedic traditions and beliefs, we have the further advantage that they were collected thousands of years ago, and handed down unchanged from that remote time. It is, therefore, not unlikely that we may find traces of the primeval Polar home in these oldest books. If the Aryan man did live within the Arctic circle in early times, especially as a portion of the Rig-Veda & Mahabharata is still admittedly unintelligible on any of the existing methods of interpretation, although the words and expressions are plain and simple in many places.
The authority for the statement is Manu, I, 67. While describing the divisions of time it says, A year (human) is a day and a night of the Gods; thus are the two divided, the northern passage of the sun is the day and the southern the night.* The day and the night of the Gods are then taken as a unit for measuring longer periods of time as the Kalpas and so on, and Yâskas Nirukta, XIV, 4, probably contains the same reference. Muir, in the first Volume of his Original Sanskrit Texts, gives some of these passages so far as they bear on the yuga-system found in the Purânas.

But we are not concerned with the later development of the idea that the day and the night of the Gods each lasted for six months. What is important, from our point of view, is the persistent prevalence of this tradition in the Vedic and the Post-Vedic literature, which can only be explained on the hypothesis that originally it must have been the result of actual observation.

Mahâbhârata gives a clear description of Mount Meru, the lord of the mountains, as to leave no doubt its being the North Pole, or possessing the Polar characteristics.
