Dr. Bisheshwar Prasad Keshari's passion for preserving the Nagpuri language and culture led him to establish "Nagpuri Sansthan" in Pithoria with his wife, Shanti Keshri, on February 17, 2002. The Sansthan is a library that serves as a repository for a vast collection of books, magazines, poems, and folk songs in tribal and regional languages, including Nagpuri. It also houses biographies of 645 Nagpuri poets and contains 117 poems of 67 poets of the Nagpuri language. The Sansthan is a testament to  Dr. B. P. Keshari's lifelong commitment to promoting the welfare and development of the people of Jharkhand by preserving their cultural heritage. It serves as a vital resource for scholars, researchers, and enthusiasts interested in learning more about the region's language and culture.
