Marathi literature began and grew owing to the rise of the Seuna dynasty of Devgiri, who adopted Marathi as the court language and patronised Marathi scholars. Further growth and usage of the language was because of two religious sects – the Mahanubhava and Varkari panthans – who adopted Marathi as the medium for preaching their doctrines of devotion. Marathi had attained a venerable place in court life by the time of the Seuna kings. During the reign of the last three Seuna kings, a great deal of literature in verse and prose, on astrology, medicine, Puranas, Vedanta, kings and courtiers were created. Nalopakhyan, Rukmini swayamvar and Shripati’s Jyotishratnamala (1039) are a few examples.
The oldest book in prose form in Marathi, Vivēkasindhu (विवेकसिंधु), was written by Mukundaraja, a Nath yogi and arch-poet of Marathi. Mukundaraja bases his exposition of the basic tenets of the Hindu philosophy and the yoga marga on the utterances or teachings of Shankaracharya. Mukundaraja’s other work, Paramamrta, is considered the first systematic attempt to explain the Vedanta in the Marathi language
