Library, single tone, silent modality. How to write? Tagore's thoughts are strange, and strange actions are strange. In his works, the existence of the library has two major functions:

The first is to store and disseminate knowledge, accept and create knowledge. But this kind of meaning is not directly and abstractly expressed, but vividly described through metaphor, personification and imagination. In the text, the library is a "silent sea wave" and a "river of people's hearts" surrounded by words and pages, which contains people's hopes, cheers of sober souls and magical voices. It is "a magnificent bridge", standing on the "unfathomable sea of years" in the past and today. Here is the distribution center of knowledge, and the voices of the sages have drifted for thousands of years, echoing here in Wan Li. And we can ride here at will, travel through time and space, and communicate with every great man and every wise man at will. You can "play the birthday song of light" as freely as the ancient philosophers here; We can start from here and move towards new glory. These novel imaginations, clever metaphors and vivid descriptions have turned the originally dull and monotonous library into a "fairyland". How can it not be fascinating?

The second is to let people get a free and relaxed mentality. "In this small place, people's self-liberation is under house arrest." Walking into the library, "no matter which direction you run, you won't encounter obstacles" and you can gallop freely. Here, you can communicate with sages on an equal footing, "defense and refutation are inseparable", "doubt and conviction, exploration and discovery, body to body" and "no one discriminates against anyone" In the library, in the face of knowledge and truth, people's status is equal and people's thoughts are free. This is Tagore's profound and unique understanding of the library, namely knowledge and truth, humanity and personality, country, nation and human society.
