Who said this:- "India is, the cradle of the human race, the birthplace of human speech, the mother of history, the grandmother of legend, and the great grand mother of tradition. Our most valuable and most instructive materials in the history of man are treasured up in India only."

Mark Twain, after visiting India in 1896-97, wrote these famous words praising India's ancient civilization in his book 'Following the Equator'. The quote eloquently describes India as the origin of human speech, history, and tradition. Other famous figures like Romain Rolland also praised India, but this specific quote is Twain's.
