In a small town, there was a library that was over a hundred years old. It had thousands of books, some of which were so rare that they could not be found anywhere else in the country. Every day, students, researchers, and even tourists came to explore its collection. The librarian, Mr. Sharma, was very knowledgeable. He guided visitors, recommending books according to their needs. He often said, “Books are not just pages; they are windows to the past, doors to the future, and mirrors to the soul.” Despite the library’s age, he maintained it meticulously, ensuring that every book remained in its proper place. Many believed that the library’s charm was not only in its collection but also in Mr. Sharma’s dedication and love for knowledge.
