How does Chapter 20 describe the fundamental nature of Sai Baba and his significance for devotees?

Chapter 20 presents a profound theological perspective on Sai Baba. It states that Sai is "originally formless, but took form for the sake of his devotees," comparing him to an actor playing the part of "Maya." The chapter refers to him as a "Siddhashram" (abode of the perfected), whose sight relieves the fatigue of worldly life and whose presence drives away delusion. He is portrayed as the ultimate refuge who can end the cycle of rebirth and grant the "shelter of eternal rest," highlighting his dual role as both the formless divine and a compassionate, accessible Satguru.
