Have you ever heard that before, Srirangan, and can you cite a reliable source for me? I need it.
I haven't read Will Durant's "Our Oriental Heritage" but here's one chilling excerpt, the only one I can find:
The Islamic conquest of India is probably the bloodiest story in history. It is a discouraging tale, for its evident moral is that civilization is a precious good, whose delicate complex of order and freedom, culture and peace, can at any moment be overthrown by barbarians invading from without or multiplying within. --Will Durant
