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.
Bless people when they revile you. Think how much good they are doing by helping to stamp out the false ego. Hold fast to the real Self. Think only pure thoughts, and you will accomplish more than a regiment of mere preachers. Out of purity and silence comes the word of power.
-Swami Vivekananda
