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 Medhatithi of Kashmir argues that sati is a form of suicide, which is prohibited by the Vedic tradition. Vijnanesvara, 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.
