Can you elaborate on the transition from 'Nirguni' to 'Saguni' as explained in Chapter 30?

Chapter 30 explains that Sai Baba's essential nature is formless, or 'Nirguni'. However, the text states that it is 'through the qualities of devotees' devotion' that 'You draw the formless into form with attributes (Saguni).' This theological point suggests that the abstract, attributeless divine principle manifests into a tangible, perceivable form as a response to the love and faith of its followers. The devotion of the bhaktas acts as a catalyst, compelling the formless Absolute to take on a personal, relatable form like Sai Baba, whom they can see, hear, and interact with.
