What does Chapter 20 reveal about Sai Baba's divine nature and his reason for taking a physical form?

Chapter 20 of the Sai Satcharitra explains that Sai Baba is "originally formless, but took form for the sake of his devotees." The text poetically describes this by stating he accepted the role of the actress "Maya" and truly played like an actor. His physical presence is described as a "Siddhashram" (abode of the perfected), where his mere sight relieves the fatigue of worldly life and drives away delusion. This highlights the teaching that his manifestation in a physical body was an act of grace and compassion for his followers.
