Who is the 'I' narrating Chapter 36, and how do they establish their authority to write about Sai's greatness?

The narrator of Chapter 36 expresses profound humility and questions their own authority to describe Sai Baba. The speaker asks, "The greatness of saints is infinite; no one can truly describe it. What authority do I have?" Rather than establishing personal authority, the narrator dismisses their own ego, or "I-ness." According to chunk 1, the narrator believes that they are merely a vessel, stating that "the playful Sai himself takes over and makes his own qualities heard by his devotees through someone." The authority, therefore, is not the author's own but is attributed directly to Sai Baba, who uses the speaker as a "mere pretext" to fulfill the desires of devotees and share his own stories.
