Can you explain the philosophical concept of Sai Baba transitioning from formless to form as described in Chapter 30?

Chapter 30 of the Sai Satcharitra presents a beautiful philosophical concept regarding Sai Baba's manifestation. The text explains that 'In the beginning, You reside as the formless (Nirguni).' It then clarifies that this formless divine presence is drawn 'into form with attributes (Saguni)' specifically 'through the qualities of devotees' devotion.' This suggests that the love and faith of the followers act as a catalyst, compelling the abstract, formless divine to take on a tangible, perceivable form. It highlights that the Saguna form of the Master is a direct response to the devotee's yearning.
