Could you summarize the main themes and analogies presented in the fifteenth chapter of the Shri Sai Satcharitra?

Chapter 15 of the Shri Sai Satcharitra begins with salutations and a humble prayer from the author to the listeners, comparing them to a vast ocean that accepts all rivers. The chapter emphasizes that listening to Sai's stories with faith leads to numerous spiritual benefits, including devotion, liberation, happiness, and the destruction of worldly fears. As described in Chapter 15, the central theme is how loving devotees pray to Sai and how He, in turn, grants them His vision. This dynamic is beautifully illustrated with the analogy of a mother cat and her kittens. The kittens eagerly approach their mother, who, despite initial annoyance, eventually succumbs to their love and provides them with nourishing milk, symbolizing how a Guru provides grace to persistent devotees.
