What specific details about Kakasaheb's connection to Shirdi does Chapter 51 promise to reveal?

Chapter 51 explicitly sets the stage for a detailed exploration of Kakasaheb's history with Shirdi, noting that while many of his stories are well-known, the circumstances of his initial arrival are not. The author promises to narrate the "marvelous account of how Kakasaheb was established in Shirdi." According to the narrative plan laid out in Chapter 51, this will include the entire history of his "bond of past lives (rinanubandh) with Shirdi" and an examination of his "firm relationship with Sai." The chapter frames this journey as a result of the grace of the Supreme Lord, obtained through the merits of past lives.
