Based on the provided text, what is Sai Baba's role in the telling of his own life stories?

Chapter 36 suggests a metaphysical role for Sai Baba in the narration of his own history. The text states that the ego or "I-ness" of the speaker is irrelevant because the "playful Sai himself takes over and makes his own qualities heard by his devotees through someone." This implies that the human narrator is merely a pretext or a channel. As Chapter 36 further explains, Sai loves his own stories and constantly provides memories of them, using the speaker and listener as instruments to fulfill the desires of his devotees and purify all who are involved.
