Can you explain the significance of the description of loving devotees praying to Sai and how He grants them His vision, as mentioned in Chapter 15?

Chapter 15 introduces its main theme by stating it will describe the prayer of loving devotees and how Sai, being pleased, grants them His vision. This is then explained through the analogy of the mother cat and her kittens. The prayer of the devotees is their persistent, loving effort to 'cling' to the Guru, just as the kittens swarm their mother. Sai granting His vision is likened to the mother cat eventually forgetting her initial annoyance and affectionately spreading herself on the ground, allowing milk to flow. As presented in Chapter 15, this illustrates that the Guru's grace, or 'vision,' is a response to the devotee's unwavering love and persistence.
