What is the spiritual meaning behind the analogy of the mother cat and her kittens in Chapter 15?

The analogy of the mother cat and her kittens in Chapter 15 serves as a powerful illustration of the relationship between a devotee and the Guru, Sai Baba. As described in the source, the kittens persistently and lovingly cling to their mother, even when she seems annoyed. Their total devotion and attachment eventually cause her milk to flow abundantly, even when their sharp claws scratch her belly. Chapter 15 explicitly connects this by stating, 'Just as the total devotion of those kittens causes the production of milk in the mother, Similarly, your attachment to Sai’s feet will melt the heart of Sai toward you.' This symbolizes how a devotee's unwavering faith, love, and persistence, even in the face of perceived silence or sternness from the Guru, will ultimately result in an outpouring of grace and spiritual nourishment.
