How does Chapter 20 describe the nature of Sai Baba and his relationship with his devotees?

According to Chapter 20, Sai Baba's true nature is formless, but he took on a physical form for the sake of his beloved devotees, much like an actor playing a role. The chapter describes him as a 'Siddhashram' (abode of the perfected), whose very sight relieves the fatigue of worldly life and drives away delusion. This is beautifully demonstrated in the scene after the noon Aarti, where his actions are filled with boundless love. He personally distributes Udi, applies it to their foreheads, and shows concern for their well-being by telling them to go and eat, showcasing his deep, personal connection to each devotee.
