What is the primary theme and central analogy used in Chapter 15 of the Shri Sai Satcharitra?

The primary theme of Chapter 15 is the description of how loving devotees pray to Sai and how he, being pleased, grants them His vision. The chapter beautifully illustrates this dynamic using the central analogy of a mother cat and her kittens. As described in the text, kittens will run to and cling to their mother for nourishment, and despite any initial annoyance, her milk begins to flow from her affection. This metaphor, as presented in Chapter 15, explains how a devotee's persistent love and clinging to the Guru ultimately results in the flow of grace and vision.
