The text mentions that Sai is 'originally formless.' How does Chapter 20 explain why he took a physical form?

Chapter 20 explains that Sai Baba is fundamentally formless but chose to take on a physical form for the sake of his devotees. The text uses a powerful metaphor, stating that Baba accepted the role of an actress named "Maya" and truly played the part like an actor. This suggests his physical manifestation was a deliberate act of compassion to make himself accessible to his followers. The chapter also describes him as a "Siddhashram" (abode of the perfected) whose mere sight could relieve the fatigue of worldly life.
