How does Chapter 20 connect Sai Baba's nature as both formless and with form to his ability to guide devotees?

Chapter 20 presents a sophisticated understanding of Sai Baba's divine nature and its connection to his role as a Guru. It posits that Sai is "originally formless, but took form for the sake of his devotees," likening this to an actor playing the role of "Maya." This act of taking a physical form makes the formless divine accessible. The chapter illustrates that through this accessible form, the "fatigue of worldly life is relieved by his sight" and the "delusion of existence... is driven away by his constant presence." Therefore, by manifesting in a form, Baba provides a tangible refuge and a direct means of guidance, as seen in his impending resolution of Das Ganu's complex spiritual doubt, ultimately helping devotees cut through the cycle of birth and death.
