How does the author of the Shri Sai Satcharitra describe his role and the origin of the book in Chapter 40?

In Chapter 40, the author, Hemadpant, humbly describes himself as a mere instrument of Sai Baba. He states, "I am merely a puppet of Sai, dancing to the pull of His strings." He insists that he is not composing the work through his own intellect and that any virtues or faults within it belong to Sai. The inspiration for the book is said to have arisen from a strong desire to describe Sai's divine deeds, like grinding grain, with the belief that recounting such stories destroys sins. The chapter emphasizes that Sai Himself is the true source, providing the intelligence and inspiration for His own story to be told for the welfare of devotees.
