What is the primary analogy used in Chapter 15 to describe the relationship between Sai and his devotees, and what does it signify?

Chapter 15 employs a detailed and powerful analogy of a mother cat and her kittens to illustrate the dynamic between Sai Baba and his followers. The text describes how kittens will persistently run to their mother, and even if she initially growls in annoyance, their unwavering love and clinging cause her to relent. Her annoyance vanishes, love arises, and milk begins to flow. As explained in Chapter 15, this signifies that a devotee's persistent and loving attachment to Sai's feet will similarly melt His heart, causing him to forget any initial sternness and shower them with grace and affection, much like the mother cat who lovingly licks her young.
