Chapter 51 mentions a 'bond of past lives' regarding Kakasaheb. What exactly does the chapter promise to narrate about him?

In Chapter 51, the narrator signals a shift in topic to focus on devotee stories, with a special emphasis on Kakasaheb. The text promises to tell the "marvelous account of how Kakasaheb was established in Shirdi." It goes beyond just his arrival, stating that it will delve into the "entire history of his bond of past lives (rinanubandh) with Shirdi and his firm relationship with Sai." This indicates that the forthcoming narrative is not just a simple biographical event but a deep exploration of the karmic and spiritual connection that drew Kakasaheb to Sai Baba. Chapter 51 notes that while many of Kakasaheb's stories are well-known, the specific details of how he first came to Shirdi are unknown to many, setting the stage for a significant revelation.
