Few men in their lifetime evoked stronger emotions or touched deeper chords of humanity than Gandhi. “Generations to come, it may be,” wrote Einstein of Gandhi in July 1944, “will scarce believe that such a one as this ever in flesh and blood walked upon this earth.” Millions venerated Gandhi as the Mahatma, The Great Soul. Gandhi was one of those who subscribed the idea that, in spite of temporary setbacks, the human race has, on the whole, been marching forward. He believed in the spirit of brotherhood and human unity. The lecture focuses on Gandhi’s life and legacy, with special reference to his technique of Satyagraha and Ahimsa, which he thought of as perhaps the mightiest instrument on earth.
