What specific stories and topics does Chapter 51 promise to narrate to its readers?

Chapter 51 serves as an introduction to the narratives that will follow. After discussing the philosophical concept of delusion from the Gita, the text promises to narrate the marvelous account of how Kakasaheb was first established in Shirdi. It mentions that while many of Kakasaheb's stories are well-known, the story of his initial arrival is not. As outlined in Chapter 51, the text will detail the history of his bond from past lives (rinanubandh) with Shirdi. Furthermore, the chapter promises to soothe the hearts of listeners by describing three stories of three different devotees.
