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.
Be brave! Be strong! Be fearless! Once you have taken up the spiritual life, fight as long as there is any life in you. Even though you know you are going to be killed, fight till you are killed. Don't die of fright. Die fighting. Don't go down till you are knocked down.
-Swami Vivekananda
