What does Chapter 20 reveal about Sai Baba's divine nature and his relationship with his devotees?

Chapter 20 portrays Sai Baba as a divine being who is 'originally formless' but took on a physical form for the sake of his devotees, much like an actor playing a role. His presence is described as a 'Siddhashram' (abode of the perfected) that relieves the fatigue of worldly life. His relationship with devotees is characterized by immense love and mercy, as shown when he distributes Udi with his own hands and applies it to their foreheads. The text states his sight drives away the 'delusion of existence' and he provides 'the shelter of eternal rest,' ending the cycle of rebirth for those who surrender to him.
