How does Chapter 20 describe Sai Baba's essential nature and his appearance in a physical form?

Chapter 20 of the Sai Satcharitra portrays Sai Baba as a divine being who is a refuge for all and can end the cycle of rebirth. It states that Sai is "originally formless" but chose to take on a physical form for the benefit of his devotees. The chapter uses the metaphor of an actress, saying that Baba accepted the role of "Maya" and played his part like a true actor. This illustrates the idea that his physical manifestation was a deliberate act of grace to make himself accessible to those who sought him, allowing them to relieve the fatigue of worldly life through his sight.
