Jimutavahana (1050-1150 AD) Sanskrit scholar and religious writer, is the first of the triumvirate of Bengali writers on Dharmashastra, the other two being shulapani and Raghunandan. Jimutavahana is famous for three books: Kalaviveka dealing with the proper times for religious rites and ceremonies, Vyavahara-matrika or Nyayaratna-matrika or Nyayamatrika dealing with vyavahara (judicial procedure), and dayabhaga dealing with the Hindu law of inheritance. In Bengal, Dayabhaga is the principal guide on inheritance, differing in some aspects from Mitaksara which is used in other parts of India. [Dhirendranath Bandyopadhyay]
