What does Chapter 20 say about the nature of Sai Baba's existence and form?

Chapter 20 presents a profound view of Sai Baba's nature. It states that 'Sai is originally formless, but took form for the sake of his devotees.' The text uses the analogy of an actor, saying Baba accepted the role of 'Maya' to interact with the world. This chapter also refers to Sai as a 'Siddhashram,' or an abode of the perfected, whose mere sight relieves worldly fatigue. His constant presence is described as a force that drives away the 'delusion of existence' for those who are close to him, highlighting his role as a liberator from worldly illusion.
