What specific devotee stories does the author promise to narrate in Chapter 51?

In Chapter 51, the author explicitly promises to narrate the history of Kakasaheb's connection to Shirdi. The text describes this as the "marvelous account of how Kakasaheb was established in Shirdi" and promises to detail the "entire history of his bond of past lives (rinanubandh) with Shirdi." The author notes that while many of Kakasaheb's stories are widely known, the specifics of how he first arrived in Shirdi are not. In addition to this main narrative, Chapter 51 also mentions that it will describe "three stories of three devotees," which are intended to bring peace and soothe the hearts of the listeners.
