The book is written by Hemadpant, but I've heard Sai is the real author. What does Chapter 47 say about who is actually telling these stories?

Chapter 47 explains the dynamic between Hemad and Sai in a very specific way. It states that Sai is the ultimate source, describing him as "the story, the speaker, and the face." The text goes on to diminish the role of the human author, asking, "In that case, who is Hemad? He is merely a nickname." This suggests that Hemad sees himself as a simple instrument or a vessel. Earlier in the chapter, it is mentioned that Sai, "the eye of the eyes and the ear of the ears," entered Hemad's heart and "himself narrated this account." Therefore, as per the details in Chapter 47, while Hemad is the writer, the true narrator and inspiration behind the stories is considered to be Sai Samarth himself.
