Using the analogy of the mother cat, how does Chapter 15 explain the seeming contradiction of a Guru's sternness and overwhelming love?

Chapter 15 masterfully uses the analogy of a mother cat to explain the complex nature of a Guru's love. The mother cat might initially growl when her kittens swarm her, which can be seen as a form of sternness or annoyance. However, the kittens' persistence and unwavering devotion cause her love to arise, making her forget her previous growling and affectionately embrace them. The text even notes that the more her belly is scratched by their sharp claws, the more the springs of love overflow. This analogy from Chapter 15 suggests that a Guru's apparent sternness is temporary and can be overcome by a devotee's total and persistent attachment, which ultimately melts the Guru's heart and results in an outpouring of grace and love.
