What specific stories does Chapter 51 promise to tell, and what is the underlying reason for meeting a Sadguru mentioned in the text?

Chapter 51 serves as an introduction to several new narratives. It specifically promises to tell the "marvelous account of how Kakasaheb was established in Shirdi," noting that this particular origin story is unknown to many. In addition to Kakasaheb's history, the chapter announces it will also describe "three stories of three devotees." The text connects this to a deeper spiritual principle, stating that it is due to the "merits of past lives" that one obtains the grace of the Supreme Lord, which in turn "leads to meeting the Sadguru and strengthening the bliss of the disciple." This concept of 'rinanubandh,' or a bond from past lives, is presented as the foundation for these sacred relationships.
