What analogy does Chapter 15 use to describe how a devotee's persistent love can win over Sai Baba?

Chapter 15 beautifully illustrates the power of a devotee's love using the analogy of a mother cat and her kittens. Initially, the mother cat might seem annoyed and growl as her kittens swarm her. However, their persistent and loving efforts to cling to her eventually cause her love to overflow, and she affectionately nurses them. The text explains that even if the kittens' sharp claws scratch her belly, her love only deepens. As stated in Chapter 15, this is compared to how a devotee's total attachment and devotion to Sai's feet will ultimately melt Sai's heart toward them, eliciting His grace and blessings.
