The earliest scholarly discussion of Sati, whether it is right or wrong, is found in the Sanskrit literature dated to 10th- to 12th-century. The earliest known commentary on Sati by Medhātithi of Kashmir argues that Sati is a form of suicide, which is prohibited by the Vedic tradition. Vijñāneśvara, of the 12th-century Chalukya court, and the 13th-century Madhvacharya, argue that sati should not to be considered suicide, which was otherwise variously banned or discouraged in the scriptures. They offer a combination of reasons, both in favor and against sati. However, according to the textbook, "Religions in the Modern World", after the death of Roop Kanwar on her husband's funeral pyre in 1987, thousands saw this as cruel murder. Committing sati was then made a crime, with consequences worse than murder.
