There are many parallels that have occurred in the recounting of various stories all over the world. For example, the Gods Indra, Zeus and Thor have identical characteristics... as do the stories of Tripura, Lanka and Atlantis. Dwarfs of the Norse are the Yakshas of the Indians, and Jotuns/Giants are the Daanavas/Daityas of India etc. There are two types of collaborations one finds with these stories.
- Physical correspondences: The physical appearance of the Gods, and men, the physical appearance of the places where they reigned, and the similarities in their names. Even the kind of weapons used (Vajra of Indra, Lightning bolt of Zeus etc.) help us to form the connecting links between them.
- Symbolic correspondences: This is found more often, where there is a parallel in the themes, and motifs which recur, in widely distributed places. An example is the attribution of the Milky Way to the Ganges in India, Nile in Egypt and Amazon in South America. Another is that of the recurring motifs in Iliad and the Mahabharata, and Eddas and Vedas. Same events under different headings.
Wherever the battle involves the "Gods" of the time, the idea is to separate out those which have occurred in the physical world with those that have their basis in the Astral World. In the Mahabharata, for example, it is mentioned again and again that the great sages and advanced beings accumulated in the skies to witness the great battles that took place. In all probability this is the collection of advanced beings in the Social Memory Complex. And if the SMC is the "sky" then the "earth" would be the Astral World.
A localized event in the Astral World would be a delocalized event in the physical world i.e. every culture would have its own version of the event by describing it in its own set of symbols, right down to identifying similar places in their country... similar to the expression of Archetypes. A physical correspondence would show how the stories spread via the migration of races, while the symbolic correspondence would show the history of a single event in different forms. When we have both physical and symbolic similarities (as is the case with Norse and Vedic) one can be reasonably sure that they are talking about the SAME event, even the two civilizations aren't exactly next door neighbours.
The Mahabharata/Trojan War was such an "astral" war, which is why it is difficult to find any conclusive physical or Archaeological evidence for the same. It would also explain the extensive uses of "Astras", the equivalent of missiles with a good dose of Magick and spells (mantras). It is most likely that the veiling fell into place completely after that war, which thus began the Kali Yuga. Hence, while comparing the mythologies from around the world, one gains an understanding not only with regard to the symbols and archetypes expressed by each Transplant civilization, but also the historical Astral events that took place.
Another aspect that comes into play here is that the different planets of the Solar System, which are physically non-localized, would be localized in the Astral world-view, with the result that groups such as the Confederation of Planets would be right next door. This would explain many mythical characters and advanced beings entering the stories at odd times, like viewers of a movie.
A side note on the Vajra: it appears that the place where the Vajra was made is very close to where I stay, hardly a 100 km!
