According to Chapter 25, why did the author feel compelled to write the Shri Sai Satcharitra?

Chapter 25 explains that the author felt a strong desire in his heart to write the life story of Shri Sai, believing that Sai Baba Himself inspired the endeavor. The text explicitly states that although the author felt he lacked the authority or knowledge, Sai inspired him, a "poor soul," to write the book with his own hands specifically "to awaken His own devotees." The author acknowledges that without Sai's command and grace, which endowed his "meager intellect with courage and special knowledge," he would not have had the audacity to undertake such a task. The ultimate purpose was to create a record for the salvation of devotees, a task the author believes Sai Himself would accept.
