What is the stated purpose of narrating Sai's stories in Chapter 36, and what specific story is introduced?

The introduction to Chapter 36 outlines a clear spiritual purpose for narrating Sai's stories. Their telling is meant to purify the ears of listeners and the mouths of speakers, helping devotees overcome worldly misery and achieve a state of happiness and devotion. The text states that Sai himself provides the memories of these stories to fulfill the desires of his devotees. After establishing this context, Chapter 36 prepares the reader for the next narrative by saying, "now listen respectfully to the most holy life story of Sai," and specifically introduces the upcoming tale of "The Two Gentlemen from Goa."
