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

According to the teachings in Chapter 27, there is a direct and beautiful correlation between the Guru's joy and the devotee's spiritual journey. The text states that the Guru finds supreme joy in whatever constitutes the devotee's own happiness. More specifically, as a devotee turns increasingly towards the spiritual path and makes progress, the Guru feels a sense of wonder and delight. This passage highlights the selfless and nurturing nature of the Sadguru, whose happiness is intrinsically linked to the spiritual well-being and advancement of their followers, rather than any personal gain. Chapter 27 shows the Guru's role is to guide the devotee away from "momentary Maya" and towards this path of spiritual growth.
