How does Chapter 51 connect the concept of 'rinanubandh' and a Sadguru's grace to the story of Kakasaheb?

Chapter 51 skillfully connects abstract spiritual concepts to the concrete story of a devotee. It states that the chapter will narrate the history of Kakasaheb's 'rinanubandh,' or bond from past lives, with Shirdi. This suggests his arrival was not accidental but preordained. The text further explains this by stating, "Due to the merits of past lives, the grace of the Supreme Lord is obtained, which leads to meeting the Sadguru and strengthening the bliss of the disciple." Therefore, as Chapter 51 frames it, Kakasaheb’s meeting with Sai and establishment in Shirdi is a direct result of his past merits and the grace that led him to his Sadguru.
