What You Will Learn

1

Introduction, Mass Extinctions & the Solar System

Why Puranic dates need a factor of two — and what that unlocks. Three major mass extinctions described in ancient texts millennia before geology confirmed them. The Solar System age accurate to within 0.11%.

Sunday, 1 March · 7:00 AM IST
2

The Big Bang, Ramayana, Narasimha & Varaha

Puranic cosmology and the age of the Universe matching Planck satellite data to 0.13%. The deeper scientific and spiritual significance hidden within the stories of Narasimha and Varaha avataras.

Sunday, 8 March · 7:00 AM IST
3

Evolution, Cosmic Distances & Embryology

What the Puranas say about the sequence of life's evolution, astronomical distances in the cosmos, and the surprisingly precise descriptions of embryonic development found in ancient Vedic texts.

How & Why — The Bigger Picture

How did ancient sages obtain this knowledge? What does it mean for how we understand Vedic wisdom today? The purpose behind these discoveries and what the Bhagavata Purana offers as a path forward.

Fields of science covered
"It is hard to find an author who is expert in widely separated branches of science, but Chhabra and O'Rourke have dexterously sewn together state-of-the-art discoveries in five fields: cosmology, astrophysics, geology, paleontology, and embryology."
— Prof. S. Ghosh, Columbia University
"The authors bury skeptics under an avalanche of well-researched facts. A real tour-de-force of scientific expertise."
— Prof. K. Pahan, Rush University
"This book illustrates how the Puranas provide both a microscopic and telescopic view of the physical world from which modern science can learn and benefit."
— Prof. R. Buyya, University of Melbourne
"You have synthesized challenging material from at least four different fields into a thought provoking and compelling vindication of the Puranic cosmo-chronological order."
— A. Saha, Smithsonian Museum of American History
