According to Chapter 25, why did the author write the Shri Sai Satcharitra, and what gave him the confidence to do so?

Chapter 25 explains that the author, despite feeling he lacked the authority, knowledge, or erudition, was directly inspired by Sai Baba to write the Shri Sai Satcharitra. As mentioned in the chapter, a desire to write the life story of Shri Sai arose in his heart, and he firmly believed that Sai Himself made him write it to awaken His devotees. The text states, "He made me write the book with my own hands to awaken His own devotees." Furthermore, the author notes that when the command was given, his "meager intellect became endowed with courage and special knowledge," giving him the confidence to undertake the sacred task for the salvation of other devotees.
