Chapter 15 uses the metaphor of a mother cat and her kittens to describe the Guru-devotee dynamic. Can you elaborate on this metaphor based on the text?

The metaphor in Chapter 15 vividly illustrates how a Guru like Sai responds to the persistent love of a devotee. The text describes how kittens run to their mother with love, even if she has just nursed them. The mother cat might initially become annoyed and growl, causing the kittens to pause. However, their love and persistence win her over. They swarm around her again, and as they cling to her, her milk begins to flow, and she forgets her previous irritation, spreading herself on the ground with affection. Chapter 15 uses this to show that a devotee's constant, loving prayers will please the Guru, who will then grant His vision and grace.
