R. Tagore’s works do not thoroughly discuss ideology. But his thoughts naturally penetrate his unique artistic work. The work that shows clearly this ideology is “The Realization of life” (Sadhana). There are also a number of articles, letters, and speeches from countries in the East and the West he had a chance to visit. Throughout these works we find the East - West spirit of dialogue. He dialogued with many philosophers who marked the dawn of the Indian civilization. And with this spirit and state of mind, he dialogued with many Western thinkers in modern times in order to seek harmony between Eastern and Western ideas to expand the base for Indian nationalism.
