How does Chapter 20 describe Sai Baba's divine nature and his personal interactions with his devotees?

In Chapter 20, Sai Baba's divine nature is described as being originally formless, but he took on a physical form for the sake of his devotees, much like an actor playing a role. The text portrays him as a 'Siddhashram' (abode of the perfected), whose mere sight can relieve the fatigue of worldly life and end the cycle of rebirths. His interactions are characterized by immense compassion and personal attention. For instance, the chapter beautifully illustrates how after the Aarti, he would distribute Udi with 'boundless love in his heart,' personally applying it to each devotee's forehead. He also showed fatherly concern by telling them to go to their lodgings for their meals.
