According to the author in Chapter 25, what was his personal role and qualification in writing the Shri Sai Satcharitra?

In Chapter 25, the author humbly explains his role as a mere instrument for a divine task. He confesses that he initially lacked the "authority, knowledge, or erudition" to undertake such a project. However, a desire arose in his heart, and he firmly believes that Sai Baba "Himself certainly made me write it." The author states that when Sai gave the command, his "meager intellect became endowed with courage and special knowledge." Therefore, as described throughout Chapter 25, he sees himself not as a qualified author, but as a poor soul chosen and inspired by Sai to write the book for the salvation and awakening of other devotees.
