Tagore paid great attention to the description of nature in Birds. A bird, a flower, a star and a drop of rain all have humanity and vitality. He loves the whole nature. He believes that there is an internal connection between human emotions and natural forces, or that nature is integrated into human emotions, or that human emotions are integrated into nature. Man and nature are inseparable and interdependent. Through the description of nature, the author expresses his philosophical thoughts and gives people inspiration. In his poetry creation, Tagore eulogized his sincere love for the people with a pure heart and expressed his praise for the beautiful things of the whole nature, the whole mankind and the whole universe.
