What is the promise made at the beginning of Chapter 36, and what new story is introduced?

At the start of Chapter 36, the narrator references a promise given in the previous chapter after the 'beautiful story of the theft was narrated.' To fulfill this promise and quench the devotees' thirst for more stories, the narrator transitions to a new tale. After a lengthy introduction on the greatness of saints and the power of Sai's stories, the chapter concludes its preamble by introducing the next narrative. As stated directly in Chapter 36, the focus shifts to a story concerning 'The Two Gentlemen from Goa,' who had come to Shirdi specifically for Sai’s darshan, thus setting the stage for the next sequence of events.
