What is the primary theme introduced in Chapter 15, and what analogy is used to illustrate the dynamic between Sai and his devotees?

Chapter 15 of the Shri Sai Satcharitra introduces the theme of loving devotees praying to Sai and how He, being pleased, grants them His vision. The text explains that listening to these stories can destroy the fear of worldly existence and fill the listeners' hearts with joy. To illustrate the relationship between Sai and His followers, the chapter uses the analogy of a mother cat and her kittens. The kittens eagerly run to their mother, who might initially growl but soon forgets her annoyance and lovingly allows them to cling to her as her milk begins to flow, representing Sai's ultimate compassion for his devoted followers.
