How does Chapter 20 explain the dual nature of Sai Baba, being both formless and having taken a form?

Chapter 20 provides a beautiful explanation of Sai Baba's nature, addressing his existence as both formless and embodied. The chapter states that Sai is "originally formless" but took on a physical form for the sake of his devotees. It uses the metaphor of an actor, saying that Baba accepted the role of the actress "Maya" and played his part masterfully on the world stage. This highlights the idea that his physical manifestation was a compassionate act to make himself accessible to followers, allowing them to relieve the fatigue of worldly life through his sight and presence, as described in this chapter.
