The popular opinion is that Vedas are apauruSeya (not man made). We will not deny that opinion, but to facilitate further discussion, we will assume Vedas were perceived by human beings who had attained a godly stage. In fact at this site we will prove that they are perceived by brain cells (in every living being) that had attained such a stage.
The development of Veda is no way different from the development of science. The Vedic seers inquired about nature using their own mind as a tool. They did every kind of experiment, explored every kind of subject, collected the eternal truths of those subjects, and compiled them together as Veda.
Just as in science, the subject of Veda is subject to change as the seers find out something better, despite the opinion of some believers that Veda can not be altered. We agree that at present there is no competent person who can change any word of Veda, or who can add a new leaf to Veda, but we can not rule out the possibility that more Vedas can not be seen again in the future. Vedas are timeless. They can be revealed in the future, and they can be revealed even in the present. Any one who denies this denies the future and the present.
Writing a new leaf of Veda is not an easy task. Anyone who can claim to do that must be competent enough to explain all the Vedas that we presently have, and in addition should answer questions of every other Vedic scholar or Vedic student on the earth on any subject related to Veda. And then, the knowledge has to be expressed in Vedic Sanskrit with the correct meter, and one has to also explain the use of the new material at an appropriate place in the yajna. That is not easy.
Veda contains two kinds of knowledge: scientific knowledge and symbolic knowledge. Truly there is no distinction between the two kinds of knowledge, but it helps in our understanding. By scientific knowledge we mean a piece of knowledge that has been proved, or at least something that is in the process of being proved using the scientific method consisting of various stages like observation, theorizing, experimentation and proof.
Example of scientific knowledge contained in the Veda is the subject of Sevenfold sAma, no one can deny the observation of Veda in this respect. At this site we will take up the remaining steps in the scientific method at an appropriate place, but there is no restriction on any one else trying to do the same. (Except that no one can patent Sevenfold sAma or its derivative concepts or products because Veda is a "Prior Art".)
If any one still wonders why Sevenfold sAma is scientific knowledge, remember, the subject of psychology is also a real science however primitive the stage it is in - in terms of explaining the nature of mind. And psychology is a legally recognized method of treatment, while Sevenfold sAma is not - because it has not yet been proven in a recognized university or laboratory and has not yet got statutory approvals for its clinical use. (It soon will.)
The example of symbolic knowledge in Veda is a statement 'Rain is uthgItha'. Symbolic knowledge explains the relationships among objects. But symbolic knowledge is nothing new to science! Modern algebra is symbolic knowledge. Java is a language to represent symbolic knowledge.
How about the so called "unproven" or "superstitious" ideas in the Vedas? Agreeably Veda has statements like "Moon is full of water". Some of these can really be superstitious, but the onus is on us to prove, not on the Veda. The original seers who revealed the Veda are not with us to explain what they meant, and the people who copiously followed the traditions to bring the materials to us over the ages did not have the authority to alter any piece of it (though we can not rule out occasional infringements due to human nature). The usual rule for preservation of any archeological asset is - if in doubt, keep it. Any thing deleted is lost to us forever!
As for water in the moon, scientists are now contemplating that the interior of moon's surface may be icy (according to a report in New York Times). Never mind if the presence of water in the moon will ever be proved, at this site we will explain that it is a valid (in fact necessary) Vedic practice to make such statements for the purpose of what we call 'Re-mystification' because as Veda always says - 'Gods love mystery as they were'.
In addition to the traditional tools, we will use whatever new tools are available including modern mathematics, fuzzy set theory, object oriented programming and others. While Sanskrit is the most natural language to express the Veda, until its features are fully explored we will settle for Java for knowledge representation. At this site we will offer some crash courses on both traditional and modern techniques to help scholars at both ends acquire a common understanding and a common language.
