How does Chapter 20 describe Sai Baba's fundamental nature and his relationship with his devotees?

Chapter 20 presents Sai Baba as a being who is "originally formless" but took on a physical form for the sake of his devotees, comparing his role to an actor playing the part of "Maya." He is described as a "Siddhashram," an abode of the perfected, whose mere sight relieves the fatigue of worldly life and whose presence drives away delusion. The chapter highlights his immense love and mercy, particularly in the scene after the noon Aarti where he distributes Udi. With "boundless love in his heart," he tends to each devotee personally, applying Udi and sending them off to eat, showcasing a deeply personal and compassionate relationship with those who seek him.
