Gyaneshwar or Dnyaneshwar, also referred to as Jnaneshwar, Jnanadeva, Dnyandev or Mauli (1275-1296) was a 13th-century Indian Marathi saint, poet, philosopher and yogi of the Nath Vaishnava tradition. In his short life of 21 years, he authored Dnyaneshwari (a commentary on the Bhagavad Gita) and Amrutanubhav. These are the oldest surviving literary works in the Marathi language, under the patronage of the Yadava dynasty of Devagiri, and these are considered to be milestones in Marathi literature. Dnyaneshwar's ideas reflect the non-dualistic Advaita Vedanta philosophy and an emphasis on Yoga and oneness of Vishnu and Shiva. His legacy inspired saint-poets such as Eknath and Tukaram, and he has been regarded as one of the founders of the Varkari (Vithoba-Krishna) Bhakti movement tradition of Hinduism in Maharashtra.
