Can you summarize the main themes and analogies presented in Chapter 15?

Chapter 15 begins with salutations and emphasizes that only those with great merit are blessed with the vision (darshan) of Sai, which helps them overcome afflictions and achieve the supreme goal. The author then humbly requests the listeners' attention, comparing them to a vast ocean that accepts all rivers, whether pure like the Ganges or a muddy stream. This chapter promises that listening to these stories with faith will grant devotion, peace, and liberation. It also introduces a key analogy, comparing the relationship between Sai and His devotees to that of a mother cat and her persistent kittens. As described in Chapter 15, just as the kittens' loving persistence causes the mother cat to relent and provide milk, the devotees' loving prayers cause Sai to grant them His vision.
