It did not strike me till the guide at Hampi told me so.
Karnataka has three types of rocks: a) Soap Stone, b) Granite, and c) Sand Stone.
Hampi (a UNESCO World Heritage) ruins are made of Granite.
The temples of Pattadakal (a UNESCO World Heritage) and the Badami Cave temples are of Sand Stone.
The temples at Belur and Halebid are made of Soap Stones.
Follow the stones and you would have covered a considerable part of Karnataka's tourism offerings.
I have just about started reading this book and I already have three of the most common emotions sweep already over me:
1) Envy: When I read this: "Sheena Iyengar is a professor at the Columbia Business School, with a joint appointment in the Department of Psychology". A women writing a best seller and is doing better than me! (I guess a bit of caveman is still alive in me)
2) Shock: When I read this: "... I was taken to a vision specialist at Columbia Presbyterian Hospital. He quickly resolved the mystery: I had a rare form of retinitis pigmentosa, an inherited disease of retinal degeneration, which had left me with 20/400 vision. By the time I reached high school, I was fully blind, able to perceive only light."
