How does Chapter 30 explain Sai Baba's nature, particularly his transition from formless to having a form?

Chapter 30 of the Sai Satcharita presents a profound theological concept about Sai Baba's existence. It describes that in the beginning, Baba resides as the formless, or 'Nirguni.' However, the text clarifies that it is through the power and qualities of his devotees' devotion that he is drawn from this formless state into a 'form with attributes,' or 'Saguni.' This teaching from Chapter 30 suggests that the physical form of the Guru that devotees could see and interact with was a manifestation brought forth by their own love and faith, making the abstract divine accessible to them. He is thus hailed as the 'crest-jewel among saints' for embodying this principle.
