What is the main focus of Chapter 51 of the Sai Satcharitra, and what stories does it promise to narrate?

Chapter 51 of the Shri Sai Satcharita transitions from a philosophical discussion to outlining its own narrative content. As detailed in the chapter, the primary focus is to narrate the "marvelous account of how Kakasaheb was established in Shirdi." It promises to explain the entire history of his bond from past lives (rinanubandh) with Shirdi and his firm relationship with Sai. The text mentions that while his stories are widely known, the tale of his initial arrival is not. Furthermore, Chapter 51 states that it will also describe three stories of three other devotees, which are intended to soothe the hearts of the listeners.
