Sri Jnanadev or Jnaneshwar, Poet and Yogi, Jnani and Bhakta, was on this earth for about twenty years, nearly seven hundred years ago. His brief life was a divine event. Jnaneshwar Maharaj had, at a very young age, a vision of the Light of Knowledge and he gave discourses on the Gita which came to be known as Bhavartha Dipika or Jnaneshwari, bringing to light the deeper meaning and hidden significance of the dialogue between the Blessed Lord and Arjuna.
If a piece of burning charcoal be placed on a man's head, see how he struggles to throw it off. Similar will be the struggle for freedom of those who really understand that they are slaves of nature.
-Swami Vivekananda
