Can you explain the connection between past merits, meeting a Sadguru, and a disciple's bliss as described in Chapter 51?

Chapter 51 of the Sai Satcharitra outlines a clear spiritual progression connecting past actions to present spiritual fortune. The text states that it is due to the merits acquired in past lives that an individual obtains the grace of the Supreme Lord. This divine grace then manifests in a tangible way by leading the person to meet a Sadguru. The chapter concludes this chain of events by stating that this meeting with the Sadguru is what ultimately strengthens the bliss of the disciple, illustrating a direct link between past virtue and present spiritual fulfillment.
