"There is an obstinate prejudice thanks to which India is constantly represented as having lived, as it were, hermetically sealed up in its age-old civilization, apart from the rest of Asia. Nothing could be more exaggerated. During the first eight centuries of our era, so far as religion and art are concerned, central Asia was a sort of Indian colony. It is often forgotten that in the early Middle Ages there existed a ‘Greater India,’ a vast Indian empire. A man coming from the Ganges or the Deccan to Southeast Asia felt as much at home there as in his own native land. In those days the Indian Ocean really deserved its name."
