All debates about historicity—i.e., who wrote what at which time and place—are irrelevant if the Vedic system is true, relevant, and better. We can stop seeing the Vedic system as mere poetry, history, literature, or belief and see it as a science.
The term “Vedic Science” makes people uncomfortable because they don’t know that what they call modern science is actually a “Christian Science”. This is because all ideologies spring out of a self-conception and model the rest of reality on that self-conception. Modern Science is based on a conception of the self given in Christianity. Vedic Science is instead based on a conception of the self given in Vedic texts.
Hence, we should ask: Which is a better self-conception? Which conception explains the world better? And which conception creates a better life? Such questions and answers make the conversation non-sectarian and pertinent to each person.
