How does Chapter 20 describe Sai Baba's fundamental nature and his loving interactions with his followers?

Chapter 20 of the Sai Satcharitra portrays Sai Baba as a being who is 'originally formless, but took form for the sake of his devotees,' likening his worldly appearance to an actor playing a role. The chapter describes his presence as a 'Siddhashram' (abode of the perfected) where the fatigue of worldly life is relieved. His interactions are characterized by immense compassion. After the noon Aarti, he is depicted with a 'most merciful gaze,' distributing Udi with 'boundless love in his heart.' He lovingly applies the ash to devotees' foreheads and then tenderly instructs them, saying 'go, all of you, to your lodgings' to eat and rest, showing his deep, personal care for their well-being.
