According to Chapter 40, what is Hemadpant's role in writing the Shri Sai Satcharitra, and who is the true author?

Chapter 40 explicitly clarifies the roles in the composition of the Shri Sai Satcharitra. Hemadpant, the narrator, insists that he is not the true author and that listeners should not attribute the virtues or faults of the work to him. The chapter uses the metaphor of a puppet and a puppeteer, stating, 'I am merely a puppet of Sai, dancing to the pull of His strings.' It emphasizes that Sai is the 'original stimulator of consciousness' who performs his own story through Hemadpant. Therefore, as described in Chapter 40, Shri Sai is the true author and inspiration, while Hemadpant is simply the chosen instrument for this divine work.
