According to Chapter 47, what is the relationship between Sai Baba and the author, Hemad, in the creation of the Satcharitra?

Chapter 47 explains that Hemad is merely an instrument or a vessel for Sai Baba's teachings. The text 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 is the story, the speaker, and the face, while Hemad is "merely a nickname." This chapter makes it clear that the ultimate source of the stories and their wisdom is Sai Baba, who uses the author to communicate His divine message to devotees.
