Based on the teachings in Chapter 30, what is the dynamic between a devotee's devotion and the manifestation of the divine, specifically regarding Sai Baba's transition from Nirguni to Saguni?

Chapter 30 presents a profound teaching on the relationship between devotion and divine manifestation. It explains that Sai Nath, in His ultimate reality, resides as the formless, or Nirguni. However, He does not remain in this abstract state in the face of sincere devotion. The chapter states that it is "through the qualities of devotees' devotion" that the formless is drawn into a form with attributes, or Saguni. This dynamic suggests that the intense love and faith of the devotee act as a powerful catalyst, compelling the formless divine to take on a tangible form to reciprocate the devotee's love and make grace accessible.
