What role does the narrator claim to have in telling the story in Chapter 47, and what is the story's intended effect on the audience?

In Chapter 47, the narrator presents himself as a humble instrument for a divine message. He states that Sai himself is the true source of the account, having entered the narrator's heart to narrate it. The author emphasizes that he is "as empty as you are" if he doesn't grasp the story's essence, highlighting that the power lies in Sai's words, not the speaker. The intended effect on the audience is described as profoundly transformative; upon hearing the story, listeners are expected to forget their bodily consciousness, be overwhelmed by divine love, and have the bonds of their Karma severed, ultimately achieving fulfillment.
