Chapter 20 mentions that Sai was 'originally formless.' How does the text explain his nature and his appearance in a physical body?

Chapter 20 explains that Sai Baba was "originally formless" but chose to take on a physical form purely for the benefit of his devotees. The text uses the metaphor of an actor, stating that Baba accepted the role of "Maya" and played his part like a true actor. This chapter also describes him as a "Siddhashram," or an abode of the perfected, whose mere sight is enough to relieve the fatigue of worldly life and whose presence drives away the delusions of existence for those who are close to him, highlighting his divine, transcendent nature.
