How does Chapter 20 explain Sai Baba's fundamental nature and his reason for having a physical form?

Chapter 20 delves into the philosophical nature of Sai Baba, explaining that He is "originally formless." The text posits that He took on a physical form and a tangible body purely for the sake of His devotees, making the divine accessible to them. This act is likened to an actor taking on a role, with Sai accepting the part of "Maya" to interact with the world and guide his followers. As described in Chapter 20, this manifestation was a compassionate choice. The chapter also refers to Sai as a Siddhashram (abode of the perfected), whose very sight is enough to relieve the fatigue of worldly life and drive away delusion.
