What does Chapter 47 reveal about the narrator's role and the origin of the story being told?

In Chapter 47, the narrator presents himself as a humble vessel for Sai Baba's words, not the true author. He states explicitly that "Sai is the eye of the eyes and the ear of the ears; Entering my heart, He himself narrated this account." This suggests the story is a divine revelation. The narrator reinforces this by admitting that he is as empty as the listeners if he fails to grasp the story's essence. His role is to introduce the story, urge listeners to focus on its inner meaning and moral, and promise that this will lead to fulfillment, as guided by Sai's own narration described in Chapter 47.
