What role does the author, Hemad, claim to have in the creation of the Shri Sai Satcharitra, as explained in Chapter 40?

In Chapter 40, the author, Hemad, humbly clarifies his role in composing the text. He insists that he is not the true creator, stating, "I am merely a puppet of Sai, dancing to the pull of His strings." The chapter explains that Sai Baba is the original stimulator of consciousness and the one who is actually performing His own story through the author. Hemad urges the listeners not to attribute any virtues or faults to him, as he believes they all belong to Sai, emphasizing that he is simply an instrument for the welfare of the devotees.
