Can you describe Sai Baba's true nature versus his physical manifestation as explained in Chapter 20?

Chapter 20 presents a profound theological concept regarding Sai Baba's being. It states that Sai is 'originally formless' but graciously took on a physical form for the ultimate benefit of his devotees. The text uses a compelling metaphor, suggesting that Baba accepted the role of the actress 'Maya' and played his part like a master actor on the world's stage. This illustrates that his human appearance was a compassionate act to make himself approachable and accessible to followers. The chapter further notes that the sight of this form relieves the fatigue of worldly life and his presence drives away the delusion of existence for those near him.
