What was Rabindranath Tagore's impact on India?

Rabindranath Tagore was a Nobel Peace Prize winner and a Indian poet and writer in colonial India. He died in 1941. Tagore was known for writing about the "universal man," a synthesis of Eastern and Western thought. He went to London in 1878 for two years, and in that time was exposed to English literature, music, and drama.
When he returned to India, his poetry and literature established new artistic and literary standards, as he had a unique view on life from his experiences in India and Britain. Through his poetry, he was able to influence both Indian and English intellectuals, poets, and writers. His poetry resonated with both Hindus and Muslims in India and Bangladesh; one of his songs was Bangladesh's national anthem, despite Bangladesh being predominantly Muslim.
He is important because he was a widely known intellectual and poet in India during years of increased nationalism. He wrote a book called Nationalism, which disagreed with Gandhi's assertion that nationalism was the best thing for India. Instead, he argued for a naturally-built human society, one that does not necessarily fit the Western concept of nation. He wrote, "When this organization of politics and commerce, whose other name is Nation, becomes all powerful at the cost of the harmony of the higher social life, then it is an evil day for humanity." Tagore witnessed the destructive nationalism of Hitler's Germany and Mussolini's Italy, thus contributing to his stance against the nation-state.
