Can you provide a summary of the main themes and events described in Chapter 15?

Chapter 15 begins with traditional salutations and a humble appeal from the author to the listeners, asking for their grace and comparing them to a vast ocean that accepts all rivers. The chapter then outlines the profound benefits of listening to the stories of saints with faith, promising that devotees will attain devotion, liberation, happiness, and peace. As explicitly stated in the text, the central theme of Chapter 15 is to describe the loving prayers of devotees to Sai and how He, being pleased, grants them His vision. This dynamic is illustrated through a detailed analogy of a mother cat and her kittens, where the kittens' persistence earns them their mother's affection and milk, symbolizing how a devotee's sincere efforts are rewarded with the Guru's grace.
