How does the author, Hemadpant, describe his own role in telling these stories about Sai?

In Chapter 47, the narrator, Hemadpant, presents his role with significant humility, positioning himself as a mere vessel for Sai's words. He states that he is simply a "nickname" and that Sai Samarth is the true story, speaker, and face behind the narrative. He even confesses that if he, as the speaker, fails to grasp the "distilled essence" of the story, he is just as empty as anyone else. This perspective, detailed in Chapter 47, emphasizes that the ultimate source and authority of the stories are believed to be Sai himself, not the human narrator.
