What is the main theme and introductory message of Chapter 15 of the Shri Sai Satcharitra?

Chapter 15 begins with traditional salutations and posits that only those with immense merit are blessed with Sai's vision, which helps them overcome afflictions and achieve the supreme goal. The author humbly asks the listeners for their attention, comparing them to a vast ocean that accepts all rivers. As detailed in this chapter, listening to these stories with faith is said to bring devotion, liberation, happiness, and peace. The chapter then introduces its central theme: describing a prayer from devotees and how Sai, pleased by their love, grants them His vision, using the analogy of a mother cat and her kittens.
