Can you summarize the main themes introduced in Chapter 15?

Chapter 15 begins by establishing the profound benefits of receiving Sai's vision, or darshan, stating that it is granted only to those with great merit and helps them overcome worldly afflictions. The author humbly requests the listeners' attention, comparing them to a vast ocean that accepts all rivers. The chapter promises that listening to these stories with patience and faith will lead to devotion, fulfillment, and liberation. As Chapter 15 details, it will specifically describe how Sai responds to the prayers of His loving devotees, granting them His vision when pleased, and uses a mother cat and kittens analogy to illustrate this.
