About the Book -: The legend of Khana also named Lilavati , she was married to the mathematician-astronomer Varahamihira, but it is far more widely believed that Khana was Varahamihira's daughter-in-law, and an accomplished astrologer, becoming thereby a potential threat to Varahamihira's scientific career. However, she exceeded him in the accuracy of her predictions, and at some point, either her husband or a hired hand or possibly Khana herself under great duress cut off her tongue to silence her prodigious talent.
