Can you explain the transition of Sai Baba from 'Nirguni' to 'Saguni' as described in the poetic verses of Chapter 30?

Chapter 30 poetically describes a profound theological concept regarding Sai Baba's nature. It begins by stating that in His ultimate reality, Sai resides as the formless, or 'Nirguni.' This is the absolute, attributeless state. However, the chapter explains that 'through the qualities of devotees' devotion, You draw the formless into form with attributes (Saguni).' This means the intense love and faith of the devotees act as a catalyst, compelling the formless divine to manifest in a perceptible, relatable form. This Saguni form is the compassionate Sai Nath that devotees can see, interact with, and whose feet they can hold, making the abstract divine accessible to the human heart.
