<P> The Mitākṣarā is a vivṛti (legal commentary) on the Yajnavalkya Smriti best known for its theory of "inheritance by birth ." It was written by Vijñāneśvara, a scholar in the Western Chalukya court in the late eleventh and early twelfth century . Along with the Dāyabhāga, it was considered one of the main authorities on Hindu Law from the time the British began administering laws in India . The entire Mitākṣarā, along with the text of the Yājñavalkya - smṝti, is approximately 492 closely printed pages . </P> <P> Vijñāneśvara lived at Marthur near Gulbarga (Karnataka), near the end of the eleventh century during the reign of Vikramaditya VI of the Cālukya dynasty of Kalyāni, one of the great rulers of the Deccan . He was a "profound student of the Purva - Mimamsa system," a system of exegetical thought focused on the interpretation of the Vedas . Contrary to Derrett's opinion based on Yajnavalkya 2.4 and 2.305 that Vijñāneśvara was a judge, Kane holds that these passages about characteristics of judges do not reflect a social or historical reality, but rather an interpretation based upon Mimamsa . </P>
