R. S. Sarthi comes from Bhataua, a small village located in Shivpuri district of Madhya Pradesh. His father, Shri Pahalwan Singh, is a middle-class farmer, and his mother, Smt. Reena Bai, is a homemaker. Sarthi is a realist writer, speaker, and teacher, with a special interest in education and teaching. His writing primarily revolves around human beings, their lives, and their social world. He makes human emotions, mental struggles, love, relationships, social behavior, the lives of young people and adolescents, and various aspects related to society and culture the subjects of his works. The fundamental purpose of his writing is to bring to light those truths about life and society that are often hidden behind illusions, conventions, fear, or pretence. He believes in calling right right and wrong wrong, questioning social norms, and understanding life as it is. For him, writing is not merely a means of expression or entertainment, but a medium for the search for truth, social dialogue, and guiding human consciousness. He is active in various genres such as novels, stories, memoirs, diaries, biographies, and conceptual and reflective writing. In particular, understanding the mental and social world of young people and adolescents, human relationships, and the complexities of life is an important aspect of his writing. Alongside his own works, he also collaborates with people who have something important to say but lack a medium to express it, helping give words to their life stories and experiences.
For R. S. Sarthi, writing is not a means of gaining popularity or personal benefit, but an effort to recognize the truth of life, understand human experiences, and leave behind a meaningful legacy of thought and experience for future generations.
