Three thousand years ago, deep inside the forests of India, a great 'thought revolution' was brewing.

In those forest labs, the brightest thinker-philosophers contemplated the universe, reflected on ancient texts called the Vedas and came up with startling insights into questions we still don't have final answers to, like:

* What is the universe made of?

* How do I know I'm looking at a tree when I see one?

* Who am I?

And where did they put those explosive findings? In a sprawling body of goosebumpy and fascinating oral literature called the Upanishads! Intimidated? Don't be! For this joyful, fun guide to some of India's longest-lasting secular wisdoms, reinterpreted for first-time explorers by Roopa Pai, is guaranteed to keep you turning the pages.
