What is the relationship between a devotee's spiritual progress and the Guru's happiness as described in Chapter 27?

Chapter 27 of the Sai Satcharitra beautifully illustrates a symbiotic relationship between a devotee's spiritual journey and the Guru's joy. The text explicitly states that the Guru finds supreme joy in whatever constitutes the devotee's own happiness. More specifically, as the devotee turns more towards the spiritual path and away from worldly Maya, the Guru feels even more wonder and delight. This suggests that the Guru's happiness is directly linked to the devotee's spiritual growth and liberation. As mentioned in Chapter 27, this dynamic underscores the Guru's selfless nature, where their ultimate satisfaction comes from seeing their devotee progress towards self-realization.
