What is the connection between past merits, meeting a Sadguru, and the purpose of spiritual narratives as explained in Chapter 51?

Chapter 51 of the Shri Sai Satcharita connects several profound spiritual concepts. It posits that encountering a Sadguru is not a random event but a direct result of "the merits of past lives," which attracts the grace of the Supreme Lord. This meeting with the Guru then serves to strengthen the bliss of the disciple. The chapter links this to the role of spiritual stories, explaining that a "tradition of spiritual narratives arises" in order to satisfy the listeners. By listening to the Sai Charitra, both the speaker and listener are purified. The text then promises to narrate stories, such as Kakasaheb's, which are intended to soothe the hearts of the listeners, reinforcing the idea that these narratives are a medium for grace and spiritual development.
