How does Chapter 25 describe the author's role and inspiration in writing the Shri Sai Satcharitra?

Chapter 25 explains that the author felt he lacked the authority, knowledge, or erudition to write the Shri Sai Charitra. However, he states that a desire arose in his heart and that Sai Baba Himself inspired and compelled him to write it. According to the text, when Sai gave the command to "keep the records," the author, who describes himself as an ignorant person, was instantly endowed with courage and special knowledge. He believes Sai made him write the book with his own hands specifically to awaken His devotees and for their salvation.
