Can you explain the relationship between a devotee's spiritual progress and the Guru's happiness as detailed in Chapter 27?

Chapter 27 highlights a profound and reciprocal relationship between the Guru and the devotee. It 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 makes progress, the Guru feels an increasing sense of wonder. This illustrates that the Guru's happiness is directly linked to the spiritual well-being and advancement of their followers. This bond is presented as a key aspect of the Guru's grace, fostering an environment where the devotee can overcome worldly attachments and find liberation.
