How does Chapter 20 explain Sai Baba's nature, particularly regarding his physical form versus his true essence?

Chapter 20 of the Shri Sai Satcharitra explains that Sai Baba's true essence is 'originally formless.' However, for the benefit and sake of his devotees, he chose to take on a physical form. The text uses a beautiful metaphor, stating that he accepted the role of the actress 'Maya' and 'truly played like an actor.' This teaching highlights that the divine, which is formless, manifests in a tangible way out of compassion, allowing devotees to connect with a physical presence. The chapter also refers to Sai as a 'Siddhashram' (abode of the perfected), whose mere sight relieves worldly fatigue and can end the cycle of rebirth.
