How does Chapter 20 describe Sai Baba's divine nature and his physical manifestation?

Chapter 20 presents a nuanced view of Sai Baba's nature. It states that Sai is "originally formless" but graciously took on a physical form for the sake of his devotees. In this role, he is likened to an actor playing a part, accepting the role of "Maya." The chapter also describes him as a "Siddhashram," an abode of the perfected, whose mere sight relieves the fatigue of worldly life and whose constant presence drives away the delusion of existence for those close to him. This portrayal highlights his dual nature as both the formless absolute and the compassionate, embodied Guru.
