How does Chapter 20 explain Sai Baba's form and why he appeared to his devotees?

According to Chapter 20, Sai Baba is described as being 'originally formless.' However, for the sake of his devotees, he took on a physical form, accepting the role of the actress 'Maya' and playing his part like an actor. This chapter emphasizes that his presence provides immense relief, describing him as a 'Siddhashram' (abode of the perfected) whose very sight alleviates the fatigue of worldly life and drives away the delusion of existence for those close to him. His grace is said to be so profound that it can end the cycle of rebirths for his followers.
