India, an ancient country, is full of strong religious atmosphere. At that time, the British colonial rulers planned to use different religious views to split the unity and will of the Indian people and disintegrate the national liberation movement of the Indian people. Tagore used pantheism in a large number of poems, aiming at guiding Indian people with different religious beliefs to overcome religious prejudice and unite against colonial rule. Tagore actively devoted himself to the practice of social change in India with love and care. His works reflect the awakening process of the Indian people and fully reflect the mainstream tendency of anti-imperialism and anti-feudalism in modern Indian literature.
