What is the primary subject matter that Chapter 15 of the Shri Sai Satcharitra introduces?

The primary subject matter introduced in Chapter 15 is a description of the prayers offered by loving devotees to Sai and how Sai, being pleased with their devotion, grants them His vision. The chapter sets the stage by promising to narrate this divine interaction. To provide a clearer picture of this dynamic, the text uses an analogy of a mother cat and her kittens. The kittens' persistent, loving approach to their mother, who eventually yields to her affection, is used to symbolize the relationship between devotees and Sai, foreshadowing the stories of devotion and grace to come.
