According to Chapter 40, who is the true author of the Shri Sai Satcharitra, and what analogy is used to describe the writer's role?

Chapter 40 clarifies that the true author and inspiration behind the Shri Sai Satcharitra is Shri Sai himself. The writer, Hemadpant, explicitly states that he is merely a puppet and Sai is the puppeteer who pulls the strings. This chapter emphasizes that Sai is the original stimulator of consciousness who performs His own story through the author. Hemadpant requests that listeners do not attribute virtues or faults to him, as they all belong to Sai, who approved the composition for the welfare of devotees.
