How does Chapter 30 describe Sai Baba's transition from formless (Nirguni) to form (Saguni)?

Chapter 30 explains that Sai Baba's essential nature is formless, or 'Nirguni'. However, the text beautifully illustrates that it is through the compelling 'qualities of devotees' devotion' that this formless essence is drawn into a tangible form with attributes, known as 'Saguni'. This concept, as articulated in Chapter 30, suggests that Sai's physical manifestation was not a random occurrence but a direct response to the deep love and faith of his followers. It portrays his form as an act of grace, making the divine accessible to those who craved a personal connection with the 'crest-jewel among saints'.
