Can you explain the role of the author, Hemadpant, and the introduction to the story about greed as described in Chapter 47?

In Chapter 47, the author, Hemadpant, presents himself as merely a vessel for Sai Baba's narration. He states, "Sai is the eye of the eyes and the ear of the ears; Entering my heart, He himself narrated this account." The chapter further diminishes the author's role by saying, "Sai Samarth himself is the story, the speaker, and the face; In that case, who is Hemad? He is merely a nickname." After referencing the previous chapter's story about the goats, Chapter 47 introduces the next narrative by asking listeners to pay attention to a story demonstrating how the extreme state of greed for wealth leads to a downfall, setting the stage for future events.
