Before we attempt to describe the world of thought revealed in the hymns of the Rigveda, the question may be asked, to what extent is there lost knowledge, lost technology, and advanced philosophy encoded within it? Is it possible to understand the true meaning of a book occupying so isolated in the remotest age of Indian literature?

The answer to this question depends on recognizing the suitable method of interpretation applicable to that ancient body of poetry. Simply, yes, there is ancient lost technology in all ancient Indian Texts; take the concept of the Vimana, for example.

When the Rigveda first became known, scholars, as yet only acquainted with the language and literature of classical Sanskrit, found that the Vedic hymns were composed in a mysterious ancient dialect and embodied a world of ideas far removed from that with which they had made themselves familiar.
