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.
There is only one sin -- and that sin is weakness. When I was a boy, I read Milton's Paradise Lost. The only good man I had any respect for was Satan. The only saint is the soul who never weakens, faces everything, and determines to die game.
-Swami Vivekananda
