What is the primary theme introduced in Chapter 15, and what analogy is used to illustrate it?

Chapter 15 introduces the central theme of how loving devotees pray to Sai and how He, being pleased by their devotion, grants them His vision. To illustrate this dynamic, the text employs a detailed analogy of a mother cat and her kittens. As described in Chapter 15, the kittens eagerly run to their mother, and even if she initially seems annoyed and growls, she eventually forgets her irritation and lovingly allows them to nurse. This interaction is presented as a metaphor for the relationship between Sai and his devotees, where persistent love is rewarded with grace.
