What is the role of the author, Hemadpant, in narrating the story in Chapter 47?

In Chapter 47, the author, Hemadpant, presents himself not as the originator of the story but merely as a medium for Sai Baba. The chapter explicitly states, "Sai is the eye of the eyes and the ear of the ears; Entering my heart, He himself narrated this account." It further diminishes the author's role by asserting that "Sai Samarth himself is the story, the speaker, and the face," and that Hemad is "merely a nickname." This establishes that the wisdom and narrative power come directly from Sai. The author reinforces this by saying he is as empty as the listeners if he doesn't grasp the essence, emphasizing that the focus should be on Sai's message as conveyed in Chapter 47.
