How does the author of the Shri Sai Satcharitra describe his own role in composing the book within Chapter 40?

In Chapter 40, the author, Hemadpant, humbly describes his role as that of a mere vessel for Sai Baba's will. He explicitly asks listeners not to attribute any virtues or faults in the writing to him, stating they all belong to Sai. He uses the powerful metaphor of being a puppet, emphasizing that Sai is the puppeteer who holds the strings and makes the puppet dance. The chapter conveys that Sai himself is the 'original stimulator of consciousness' who is actually performing and telling his own story, using the author as an instrument for the welfare of the devotees.
