How does Chapter 20 describe the fundamental nature of Sai Baba, particularly regarding his form?

Chapter 20 of the Sai Satcharitra offers a profound description of Sai Baba's nature, presenting him as both formless and with form. The text explicitly states, "Sai is originally formless, but took form for the sake of his devotees." This highlights a key theological point that his essential being is beyond physical manifestation, but he chose to appear in a human body for the benefit of his followers. The chapter further illustrates this by saying he accepted the role of "Maya" and played his part like an actor. This chapter also refers to him as a "Siddhashram" (abode of the perfected), whose mere sight could relieve worldly fatigue and delusion.
