How does Chapter 15 interrelate the concepts of a devotee's merit, the listener's grace, and the Guru's response?

Chapter 15 skillfully weaves together several key spiritual concepts to frame the narrative. It begins by positing that attaining the 'darshan' (vision) of Sai is a direct result of immense merit, leading to the supreme goal. The author then appeals to the listeners for their grace, comparing them to an all-accepting ocean, suggesting that their open-heartedness is crucial for the transmission of the stories. Finally, as described in Chapter 15, the text illustrates the Guru's response to devotion using the analogy of the mother cat and her kittens. This shows that the persistent, loving efforts of the devotee can elicit a flow of grace from the Guru. Thus, the chapter presents a holistic spiritual dynamic where past merit, the receiver's grace, and active devotion all play a role in manifesting divine blessings.
