How does the author of the Shri Sai Satcharitra describe his role in writing the book, and what does he say about Sai Baba's involvement?

The author expresses profound humility, feeling completely unqualified for the task of writing Sai Baba's life story. As described in Chapter 3, he sees himself as the "most insignificant of all" and lacking knowledge. However, he states that Sai Baba Himself is the true author. The text explains, "When the pen was lifted in hand, Baba took away my 'I-ness' (ego). He writes His own story Himself; the glory belongs to Him." The author compares himself to an instrument, like a flute or harmonium, which only produces sound through the effort of the player, who in this case is Sai Baba, accomplishing the work for the welfare of devotees.
