According to Chapter 25, what was the author's motivation and perceived authority for writing the Shri Sai Satcharitra?

In Chapter 25, the author reveals that a desire arose in his heart to write the life story of Shri Sai. He openly admits that he lacked the authority, knowledge, or erudition for such a task. However, he states that Sai Baba himself inspired him, a self-described "poor soul," and commanded him to "Keep the records." This divine command endowed the author's meager intellect with courage and special knowledge. The author believes that Sai made him write the book to awaken his own devotees and that Sai himself will accept the work for their salvation.
