Based on the teachings in Chapter 27, how is the relationship between a Guru's happiness and a devotee's spiritual progress described?

Chapter 27 beautifully illustrates the symbiotic relationship between a Guru and a devotee. It states that the Guru finds supreme joy in whatever constitutes the devotee's own happiness. More specifically, the Guru feels a sense of wonder and delight as the devotee turns more towards the spiritual path. This suggests that the Guru's happiness is directly linked to the spiritual advancement and well-being of their follower. The chapter emphasizes that for this spiritual progress to occur, one must have ultimate faith in the Guru's feet, which leads to the subsidence of passions and the emergence of supreme love, a state that brings joy to the Guru.
