Can you explain the philosophical concept of Sai Baba transitioning from 'Nirguni' to 'Saguni' as mentioned in Chapter 30?

Chapter 30 of the Sri Sai Satcharitra presents a profound concept about Sai Baba's divine nature. It states that initially, He exists as 'Nirguni,' the formless, attributeless absolute reality. However, the chapter explains that it is through the compelling power of the devotees' love and devotion that He is drawn into 'Saguni,' a form with attributes. This manifestation allows devotees to connect with, worship, and understand Him. The text says, "through the qualities of devotees' devotion, You draw the formless into form with attributes." This illustrates that the Guru's physical form is a compassionate response to the devotee's yearning.
