How does Chapter 20 describe Sai Baba's fundamental nature and his purpose for taking a physical form?

Chapter 20 of the Sai Satcharitra 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.' In doing so, he accepted the role of the actress 'Maya,' playing his part like a true actor. The chapter also describes him as a 'Siddhashram' (abode of the perfected), whose mere sight relieves the fatigue of worldly life and drives away delusion. He is hailed as a refuge who provides the 'shelter of eternal rest' and ends the cycle of rebirth for his surrendered devotees, showcasing his divine and compassionate essence.
