What is the specific narrative event that Chapter 15 promises to describe, and how is it framed?

Chapter 15 serves as an introduction that frames a specific narrative to come. The text explicitly states, "In this chapter, the description: the prayer of loving devotees to Sai; Listen to how Sai, being pleased, grants them His vision." This sets the stage for a story about the power of heartfelt prayer and Sai Baba's compassionate response. The chapter frames this event using a tender analogy of a mother cat and her kittens. This comparison suggests that the devotees' prayers are like the kittens' persistent affection, which ultimately moves the mother cat (Sai) to forget any initial sternness and respond with loving grace. Therefore, as Chapter 15 indicates, the forthcoming story is about how sincere devotion can earn the Guru's cherished vision.
